Abortion in the United States has been and remains one of the most controversial issues in United States culture and politics. Various anti-abortion laws have been in force in each state since at least 1900.
Before the U.S. Supreme Court decision Roe v. Wade legalized abortion nationwide in 1973, it was already legal in several states, but the decision imposed a uniform framework for state legislation on the subject. It established a minimal period during which abortion must be legal (with more or fewer restrictions throughout the pregnancy). That basic framework, modified in Planned Parenthood v. Casey (1992), remains nominally in place, although the effective availability of abortion varies significantly from state to state, as many counties have no abortion providers.
In the United States, the main actors in the abortion debate are most often labeled either as "pro-choice" or "pro-life", though shades of opinion exist, and most Americans are considered to be somewhere in the middle. A Gallup.com survey of 1014 adults found that opinions on abortion in the United States remain nearly evenly split, with 46% of participants identifying as pro-life and 47% identifying as pro-choice. The poll results also indicated that Americans harbor a diverse and shifting set of opinions on the legal status of abortion in the US; the survey polled that only 28% of respondents believed abortion should be legal under unlimited circumstances, and 48% of respondents believed that abortion should be legal under "most" or "only a few circumstances." Recent polling results also found that only 34% of Americans were satisfied with abortion laws in the United States.
The abortion debate most commonly relates to the "induced abortion" of an embryo or fetus at some point in a pregnancy, which is also how the term is used in a legal sense. Some also use the term "elective abortion", which is used in relation to a claim to an unrestricted right of a woman to an abortion, whether or not she chooses to have one.
In medical parlance, "abortion" can refer to either miscarriage or abortion until the fetus is viable. After viability, doctors call an abortion a "termination of pregnancy".
When the United States first became independent, most states applied English common law to abortion. This meant it was not permitted after quickening, or the start of fetal movements, usually felt 15–20 weeks after conception. James Wilson, a framer of the U.S. Constitution, explained the view as follows:
|“||With consistency, beautiful and undeviating, human life, from its commencement to its close, is protected by the common law. In the contemplation of law, life begins when the infant is first able to stir in the womb. By the law, life is protected not only from immediate destruction, but from every degree of actual violence, and, in some cases, from every degree of danger.||”|
Abortions became illegal by statute in Britain in 1803, and various anti-abortion statutes began to appear in the United States in the 1820s that codified or expanded common law. In 1821, a Connecticut law targeted apothecaries who sold "poisons" to women for purposes of inducing an abortion, and New York made post-quickening abortions a felony and pre-quickening abortions a misdemeanor in 1829. Some argue that the early American abortion laws were motivated not by ethical concerns about abortion but by concern about the procedure's safety. However, some legal theorists point out that this theory is inconsistent with the fact that abortion was punishable regardless of whether any harm befell the pregnant woman and the fact that many of the early laws punished not only the doctor or abortionist, but also the woman who hired them.
A number of other factors likely played a role in the rise of anti-abortion laws in the United States. Physicians, who were the leading advocates of abortion criminalization laws, appear to have been motivated at least in part by advances in medical knowledge. Science had discovered that conception inaugurated a more or less continuous process of development, which would produce a new human being if uninterrupted. Moreover, quickening was found to be neither more nor less crucial in the process of gestation than any other step. On a logical basis, many physicians concluded that if society considered it unjustifiable to terminate pregnancy after the fetus had quickened, and if quickening was a relatively unimportant step in the gestation process, then it was just as wrong to terminate a pregnancy before quickening as after quickening. Ideologically, the Hippocratic Oath and the medical mentality of that age to defend the value of human life as an absolute also played a significant role in molding opinions about abortion. Doctors were also influenced by practical reasons to impose anti-abortion laws. For one, abortion providers tended to be untrained and not members of medical societies. In an age where the leading doctors in the nation were attempting to standardize the medical profession, these "irregulars" were considered a nuisance to public health. The more formalized medical profession disliked the "irregulars" because they were competition, often at a cheaper cost.
Despite campaigns to end the practice of abortion, abortifacient advertising was highly effective in the United States, though less so across the Atlantic. Contemporary estimates of mid-19th century abortion rates in the United States suggest between 20–25% of all pregnancies in the United States during that era ended in abortion. This era saw a marked shift in those who were obtaining abortions. Before the start of the 19th century, most abortions were sought by unmarried women who had become pregnant out of wedlock. Out of 54 abortion cases published in American medical journals between 1839 and 1880, over half were sought by married women, and well over 60% of the married women already had at least one child. The sense that married women were now frequently obtaining abortions worried many conservative physicians, who were almost exclusively men. In the post-Civil War era, much of the blame was placed on the burgeoning women's rights movement.
Though the medical profession expressed hostility toward feminism, many feminists of the era were opposed to abortion. In The Revolution, operated by Elizabeth Cady Stanton and Susan B. Anthony, an anonymous contributor signing "A" wrote in 1869 about the subject, arguing that instead of merely attempting to pass a law against abortion, the root cause must also be addressed. Simply passing an anti-abortion law would, the writer stated, "be only mowing off the top of the noxious weed, while the root remains. [...] No matter what the motive, love of ease, or a desire to save from suffering the unborn innocent, the woman is awfully guilty who commits the deed. It will burden her conscience in life, it will burden her soul in death; But oh! thrice guilty is he who drove her to the desperation which impelled her to the crime." To many feminists of this era, abortion was regarded as an undesirable necessity forced upon women by thoughtless men. Even the "free love" wing of the feminist movement refused to advocate for abortion and treated the practice as an example of the hideous extremes to which modern marriage was driving women. Marital rape and the seduction of unmarried women were societal ills which feminists believed caused the need to abort, as men did not respect women's right to abstinence.
However, physicians remained the loudest voice in the anti-abortion debate, and they carried their anti-feminist agenda to state legislatures around the country, advocating not only anti-abortion laws, but also laws against birth control. This movement presaged the modern debate over women's body rights. A campaign was launched against the movement and the use and availability of contraceptives.
Criminalization of abortion accelerated from the late 1860s, through the efforts of concerned legislators, doctors, and the American Medical Association. In 1873, Anthony Comstock created the New York Society for the Suppression of Vice, an institution dedicated to supervising the morality of the public. Later that year, Comstock successfully influenced the United States Congress to pass the Comstock Law, which made it illegal to deliver through the U.S. mail any "obscene, lewd, or lascivious" material. It also prohibited producing or publishing information pertaining to the procurement of abortion or the prevention of conception or venereal disease, even to medical students. The production, publication, importation, and distribution of such materials was suppressed under the Comstock Law as being obscene, and similar prohibitions were passed by 24 of the 37 states.
In 1900, abortion was a felony in every state. Some states included provisions allowing for abortion in limited circumstances, generally to protect the woman's life or to terminate pregnancies arising from rape or incest. Abortions continued to occur, however, and became increasingly available. The American Birth Control League was founded by Margaret Sanger in 1921 to promote the founding of birth control clinics and enable women to control their own fertility.
By the 1930s, licensed physicians performed an estimated 800,000 abortions a year.
In 1964 Gerri Santoro of Connecticut died trying to obtain an illegal abortion and her photo became the symbol of the pro-choice movement. Some women's rights activist groups developed their own skills to provide abortions to women who could not obtain them elsewhere. As an example, in Chicago, a group known as "Jane" operated a floating abortion clinic throughout much of the 1960s. Women seeking the procedure would call a designated number and be given instructions on how to find "Jane".
In 1965, the U.S. Supreme Court case Griswold v. Connecticut struck down one of the remaining contraception Comstock laws in Connecticut and Massachusetts. However, Griswold only applied to marital relationships. Eisenstadt v. Baird (1972) extended its holding to unmarried persons as well. Following Griswold case, the American College of Obstetricians and Gynecologists (ACOG) issued a medical bulletin accepting a recommendation from 6 years earlier which clarified that conception is implantation, not fertilization; and consequently birth control methods that prevented implantation became classified as contraceptives, not abortifacients.
In 1967, Colorado became the first state to decriminalize abortion in cases of rape, incest, or in which pregnancy would lead to permanent physical disability of the woman. Similar laws were passed in California, Oregon, and North Carolina. In 1970, Hawaii became the first state to legalize abortions on the request of the woman, and New York repealed its 1830 law and allowed abortions up to the 24th week of pregnancy. Similar laws were soon passed in Alaska and Washington. A law in Washington, D.C., which allowed abortion to protect the life or health of the woman, was challenged in the Supreme Court in 1971 in United States v. Vuitch. The court upheld the law, deeming that "health" meant "psychological and physical well-being," essentially allowing abortion in Washington, DC. By the end of 1972, 13 states had a law similar to that of Colorado, while Mississippi allowed abortion in cases of rape or incest only and Alabama and Massachusetts allowed abortions only in cases where the woman's physical health was endangered. In order to obtain abortions during this period, women would often travel from a state where abortion was illegal to states where it was legal. The legal position prior to Roe v. Wade was that abortion was illegal in 30 states and legal under certain circumstances in 20 states.
In the late 1960s, a number of organizations were formed to mobilize opinion both against and for the legalization of abortion. In 1966, the National Conference of Catholic Bishops assigned Monsignor James T. McHugh to document efforts to reform abortion laws, and anti-abortion groups began forming in various states in 1967. In 1968, McHugh led an advisory group which became the National Right to Life Committee. The forerunner of the NARAL Pro-Choice America was formed in 1969 to oppose restrictions on abortion and expand access to abortion. Following Roe v. Wade, in late 1973 NARAL became the National Abortion Rights Action League.
Prior to Roe v. Wade, 30 states prohibited abortion without exception, 20 states banned abortion except in certain special circumstances (e.g.: rape, incest, health threat to mother), 3 states allowed residents to obtain abortions, and New York allowed abortions generally.  Early that year, on January 22, 1973, the Supreme Court in Roe v. Wade invalidated all of these laws, and set guidelines for the availability of abortion. Roe established that the right of privacy of a woman to obtain an abortion "must be considered against important state interests in regulation." Roe established a "trimester" (i.e., 12 week) threshold of state interest in the life of the fetus corresponding to its increasing "viability" (likelihood of survival outside the uterus) over the course of a pregnancy, such that states were prohibited from banning abortion early in pregnancy but allowed to impose increasing restrictions or outright bans later in pregnancy.
In deciding Roe v. Wade, the Supreme Court ruled that a Texas statute forbidding abortion except when necessary to save the life of the mother was unconstitutional. The Court arrived at its decision by concluding that the issue of abortion and abortion rights falls under the right to privacy (in the sense of the right of a person not to be encroached by the state). In its opinion it listed several landmark cases where the court had previously found a right to privacy implied by the Constitution. The Court did not recognize a right to abortion in all cases:
State regulation protective of fetal life after viability thus has both logical and biological justifications. If the State is interested in protecting fetal life after viability, it may go so far as to proscribe abortion during that period, except when it is necessary to preserve the life or health of the mother.
The Court held that a right to privacy existed and included the right to have an abortion. The court found that a mother had a right to abortion until viability, a point to be determined by the abortion doctor. After viability a woman can obtain an abortion for health reasons, which the Court defined broadly to include psychological well-being.
A central issue in the Roe case (and in the wider abortion debate in general) is whether human life or personhood begins at conception, birth, or at some point in between. The Court declined to make an attempt at resolving this issue, noting: "We need not resolve the difficult question of when life begins. When those trained in the respective disciplines of medicine, philosophy, and theology are unable to arrive at any consensus, the judiciary, at this point in the development of man's knowledge, is not in a position to speculate as to the answer." Instead, it chose to point out that historically, under English and American common law and statutes, "the unborn have never been recognized ...as persons in the whole sense" and thus the fetuses are not legally entitled to the protection afforded by the right to life specifically enumerated in the Fourteenth Amendment. So rather than asserting that human life begins at any specific point, the court simply declared that the State has a "compelling interest" in protecting "potential life" at the point of viability.
Under Roe v Wade, state governments may not prohibit late terminations of pregnancy when "necessary to preserve the [woman's] life or health", even if it would cause the demise of a viable fetus. This rule was clarified by the 1973 judicial decision Doe v Bolton, which specifies "that the medical judgment may be exercised in the light of all factors—physical, emotional, psychological, familial, and the woman's age—relevant to the well-being of the patient." It is by this provision for the mother's mental health that women in the US legally choose abortion after viability when screenings reveal abnormalities that do not cause a baby to die shortly after birth.
"Jane Roe" of the landmark Roe v. Wade lawsuit, whose real name is Norma McCorvey, is now a pro-life advocate. McCorvey writes that she never had the abortion and became the "pawn" of two young and ambitious lawyers who were looking for a plaintiff who they could use to challenge the Texas state law prohibiting abortion. However, attorney Linda Coffee says she does not remember McCorvey having any hesitancy about wanting an abortion.
"Mary Doe" of the companion Doe v. Bolton lawsuit, the mother of three whose real name is Sandra Cano, maintains that she never wanted or had an abortion and that she is "ninety-nine percent certain that [she] did not sign" the affidavit to initiate the suit.
In the 1992 case of Planned Parenthood v. Casey, the Court abandoned Roe's strict trimester framework. Roe had held that to be "strict scrutiny"—the traditional Supreme Court test for impositions upon fundamental Constitutional rights, whereas Casey adopted the standard of undue burden for evaluating state abortion restrictions, but reemphasized the right to abortion as grounded in the general sense of liberty and privacy protected under the constitution: "Constitutional protection of the woman's decision to terminate her pregnancy derives from the Due Process Clause of the Fourteenth Amendment. It declares that no State shall 'deprive any person of life, liberty, or property, without due process of law.' The controlling word in the cases before us is 'liberty'."
The Supreme Court continues to grapple with cases on the subject. On April 18, 2007 it issued a ruling in the case of Gonzales v. Carhart, involving a federal law entitled the Partial-Birth Abortion Ban Act of 2003 which President George W. Bush had signed into law. The law banned intact dilation and extraction, which opponents of abortion rights referred to as "partial-birth abortion," and stipulated that anyone breaking the law would get a prison sentence up to 2.5 years. The United States Supreme Court upheld the 2003 ban by a narrow majority of 5-4, marking the first time the Court has allowed a ban on any type of abortion since 1973. The opinion, which came from justice Anthony Kennedy, was joined by Justices Antonin Scalia, Clarence Thomas, and the two recent appointees, Samuel Alito and Chief Justice John Roberts.
In the case of Whole Woman's Health v. Hellerstedt the Supreme Court in a 5-3 decision on June 27, 2016 swept away forms of state restrictions on the way abortion clinics can function. The Texas legislature enacted in 2013 restrictions on the delivery of abortions services that created an undue burden for women seeking an abortion by requiring abortion doctors to have difficult-to-obtain "admitting privileges" at a local hospital and by requiring clinics to have costly hospital-grade facilities. The Court struck down these two provisions "facially" from the law at issue—that is, the very words of the provisions were invalid, no matter how they might be applied in any practical situation. According the Supreme Court the task of judging whether a law puts an unconstitutional burden on a woman's right to abortion belongs with the courts and not the legislatures.
Since 1995, led by congressional Republicans, the U.S. House of Representatives and U.S. Senate have moved several times to pass measures banning the procedure of intact dilation and extraction, commonly known as partial birth abortion. Such measures passed twice by wide margins, but President Bill Clinton vetoed those bills in April 1996 and October 1997 on the grounds that they did not include health exceptions. Congressional supporters of the bill argue that a health exception would render the bill unenforceable, since the Doe v. Bolton decision defined "health" in vague terms, justifying any motive for obtaining an abortion. Congress was unsuccessful with subsequent attempts to override the vetoes.
The Born-Alive Infants Protection Act of 2002 ("BAIPA") was enacted August 5, 2002 by an Act of Congress and signed into law by George W. Bush. It asserts the human rights of infants born after a failed attempt to induce abortion. A "born-alive infant" is specified as a "person, human being, child, individual." "Born alive" is defined as the complete expulsion of an infant at any stage of development that has a heartbeat, pulsation of the umbilical cord, breath, or voluntary muscle movement, no matter if the umbilical cord has been cut or if the expulsion of the infant was natural, induced labor, cesarean section, or induced abortion.
On October 2, 2003, with a vote of 281-142, the House approved the Partial-Birth Abortion Ban Act to ban partial-birth abortion, with an exemption in cases of fatal threats to the woman. Through this legislation, a doctor could face up to two years in prison and civil lawsuits for performing such a procedure. A woman undergoing the procedure could not be prosecuted under the measure. On October 21, 2003, the United States Senate passed the bill by a vote of 64-34, with a number of Democrats joining in support. The bill was signed by President George W. Bush on November 5, 2003, but a federal judge blocked its enforcement in several states just a few hours after it became public law. The Supreme Court upheld the nationwide ban on the procedure in the case Gonzales v. Carhart on April 18, 2007, signaling a substantial change in the Court's approach to abortion law. The 5-4 ruling said the Partial Birth Abortion Ban Act does not conflict with previous decisions regarding abortion.
The current judicial interpretation of the U.S. Constitution regarding abortion in the United States, following the Supreme Court of the United States's 1973 landmark decision in Roe v. Wade, and subsequent companion decisions, is that abortion is legal but may be restricted by the states to varying degrees. States have passed laws to restrict late term abortions, require parental notification for minors, and mandate the disclosure of abortion risk information to patients prior to the procedure.
|“||All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.||”|
The official report of the U.S. Senate Judiciary Committee, issued in 1983 after extensive hearings on the Human Life Amendment (proposed by Senators Orrin Hatch and Thomas Eagleton), stated what substantially remains true today:
|“||Thus, the [Judiciary] Committee observes that no significant legal barriers of any kind whatsoever exist today in the United States for a mother to obtain an abortion for any reason during any stage of her pregnancy.||”|
One aspect of the legal abortion regime now in place has been determining when the fetus is "viable" outside the womb as a measure of when the "life" of the fetus is its own (and therefore subject to being protected by the state). In the majority opinion delivered by the court in Roe v. Wade, viability was defined as "potentially able to live outside the mother's womb, albeit with artificial aid. Viability is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks." When the court ruled in 1973, the then-current medical technology suggested that viability could occur as early as 24 weeks. Advances over the past three decades have allowed fetuses that are a few weeks less than 24 weeks old to survive outside the woman's womb. These scientific achievements, while life-saving for premature babies, have made the determination of being "viable" somewhat more complicated.
As of 2006[update], the youngest child to survive a premature birth in the United States was a girl born at Kapiolani Medical Center in Honolulu, Hawaii at 21 weeks and 3 days gestation. Because of the split between federal and state law, legal access to abortion continues to vary by state. Geographic availability varies dramatically, with 87 percent of U.S. counties having no abortion provider. Moreover, due to the Hyde Amendment, many state health programs do not cover abortions; currently 17 states (including California, Illinois and New York) offer or require such coverage.
The legality of abortion in the United States is frequently a major issue in nomination battles for the U.S. Supreme Court. Nominees typically remain silent on the issue during their hearings, as the issue may come before them as judges.
The Unborn Victims of Violence Act, commonly known as "Laci and Conner's Law" was passed by Congress and signed into law by President Bush on April 1, 2004, allowing two charges to be filed against someone who kills a pregnant mother (one for the mother and one for the fetus). It specifically bans charges against the mother and/or doctor relating to abortion procedures. Nevertheless, it has generated much controversy among pro-choice advocates who view it as a potential step in the direction of banning abortion.
Various states have laws on abortion, some of which refer to it as feticide. On March 6, 2006, South Dakota Governor Mike Rounds signed into law a pro-life statute that made performing abortions a felony, which was subsequently repealed in a November 7, 2006 referendum. On February 27, 2006, Mississippi's House Public Health Committee voted to approve a ban on abortion, and that bill died after the House and Senate failed to agree on compromise legislation. Several states have enacted "trigger laws" which "would take effect if Roe v. Wade is overturned." North Dakota HB 1572 or the Personhood of Children Act, which passed the North Dakota House of Representatives on February 18, 2009, but was later defeated in the North Dakota Senate, aimed to allocate rights to "the pre-born, partially born", and if passed, would likely have been used to challenge Roe v. Wade. On February 15, 2012, the Virginia House of Delegates passed House Bill 1 in a vote of 66-32, that effectively outlaws all Virginia abortions by declaring that the rights of persons apply from the moment sperm and egg unite. It also passed a second bill in a 63-36 vote, that requires women to have a transvaginal ultrasound before undergoing abortions.
Some states have sought to ban abortion by means of an amendment to the state constitution, three of which have reached the ballot for a vote. Colorado citizens voted on Amendment 48 on November 4, 2008, but it failed to pass, with 73.21% voting against it and 26.79% voting for it. A similar initiative, Amendment 62, made the Colorado ballot on November 2, 2010, where it failed again, this time 70.53% to 29.47%. On November 8, 2011, Initiative 26, a "personhood" measure that would have banned all abortions and some forms of contraception, was defeated on the Mississippi ballot, 57.87% voting "no" to 42.13%. All three of these amendments made it to the ballot through a citizen initiative process, as opposed to being referred to the ballot by their state legislatures.
These amendments, dubbed "personhood amendments," have contained far-reaching language that go beyond simply banning abortion. They define personhood as beginning from the moment of conception or fertilization, which would potentially outlaw forms of birth control, in addition to potentially banning in-vitro fertilization. The umbrella organization Personhood USA, based in Colorado and co-founded by Cal Zastrow and Keith Mason, was responsible for getting Amendments 48 and 62 onto the ballot in Colorado. Personhood USA also plans on pushing for such amendments in Montana and Oregon.

Other states are considering personhood amendments banning abortion, some through legislative methods and others through citizen initiative campaigns. Among these states are Florida, Ohio, Georgia, Texas, and Arkansas.
24 states have mandatory counseling and delay periods, while 6 states require in person counseling. 
Abortion in the Northern Mariana Islands, a United States Commonwealth, is illegal.
Qualifying requirements for performing abortions vary from state to state. Currently, California, Oregon, Montana, Vermont, and New Hampshire allow qualified non-physician health professionals, such as physicians' assistants, nurse practitioners, and certified nurse midwives, to do first-trimester aspiration abortions and to prescribe drugs for medical abortions. Washington State, New Mexico, Illinois, Alaska, Maryland, New York, Massachusetts, Connecticut, and New Jersey allow qualified non-physicians to prescribe drugs for medical abortions only. In all other states, only licensed physicians may perform abortions. In 2016, the FDA issued new guidelines recommending that qualified non-physician health-care professionals be allowed to prescribe mifepristone in all states; however, these guidelines are not binding and states are free to determine their own policies regarding mifepristone.

The annual number of legal induced abortions in the United States doubled between 1973 and 1979, and peaked in 1990. There was a slow but steady decline through the 1990s. Overall, the number of annual abortions decreased by 6% between 2000 and 2009, with temporary spikes in 2002 and 2006.
By 2011, abortion rate in the United States dropped to its lowest point since the Supreme Court legalized the procedure. According to a study performed by Guttmacher Institute, long-acting contraceptive methods were having a significant impact in reducing unwanted pregnancies. There were fewer than 17 abortions for every 1,000 women of child-bearing age. That was a 13 percent decrease from 2008's numbers and slightly higher than the rate in 1973, when the Supreme Court's Roe v. Wade decision legalized abortion. The study indicated a long-term decline in the abortion rate. The rate has dropped significantly from its all-time high in 1981, when there were roughly 30 abortions for every 1,000 women of reproductive age. The overall number of abortions also fell 13 percent from 2008 to nearly 1.1 million in 2011." In 2013, the Centers for Disease Control and Prevention also reported a decline in abortion rates.
Even though abortion is legal, abortion can carry heavy social stigma; for this reason incidence of abortions may be difficult to measure because in medicine they can be reported variously as miscarriage, "induced miscarriage", "menstrual regulation", "mini-abortion", and "regulation of a delayed/suspended menstruation".
A Guttmacher Institute survey of abortion providers estimated that early medical abortions accounted for 17% of all nonhospital abortions and slightly over one-quarter of abortions before 9 weeks gestation in the United States in 2008. Medical abortions voluntarily reported to the CDC by 34 reporting areas (excluding Alabama, California, Connecticut, Delaware, Florida, Hawaii, Illinois, Louisiana, Maryland, Massachusetts, Nebraska, Nevada, New Hampshire, Pennsylvania, Tennessee, Vermont, Wisconsin, and Wyoming) and published in its annual abortion surveillance reports have increased every year since the September 28, 2000 FDA approval of mifepristone (RU-486): 1.0% in 2000, 2.9% in 2001, 5.2% in 2002, 7.9% in 2003, 9.3% in 2004, 9.9% in 2005, 10.6% in 2006, 13.1% in 2007, 15.8% in 2008, 17.1% in 2009 (25.2% of those at less than 9 weeks gestation). Medical abortions accounted for 32% of first trimester abortions at Planned Parenthood clinics in the United States in 2008.
Abortion is common among religiously identified women. According to the Guttmacher Institute, "[m]ore than 7 in 10 U.S. women obtaining an abortion report a religious affiliation (37% protestant, 28% Catholic and 7% other), and 25% attend religious services at least once a month. The abortion rate for protestant women is 15 per 1,000 women, while Catholic women have a slightly higher rate, 22 per 1,000."
Abortion rates tend to be higher among minority women in the U.S. In 2000-2001 due to lower access to healthcare and contraception. The rates among black and Hispanic women were 49 per 1,000 and 33 per 1,000, respectively, vs. 13 per 1,000 among non-Hispanic white women. Note that this figure includes all women of reproductive age, including women that are not pregnant. In other words, these abortion rates reflect the rate at which U.S. women of reproductive age have an abortion each year. While White women obtain 60% of all abortions, African American women are three times more likely to have an abortion. In 2012, New York City reported abortions (31,328) outnumber live births (24,758) for black children. Black and Hispanic abortions combined (54,245), account for 73% of the total abortions in the city in 2012, according to a report by the New York City Department of Health and Mental Hygiene, Office of Vital Statistics.

According to the Centers for Disease Control, in 2011, most (64.5%) abortions were performed by ≤8 weeks' gestation, and nearly all (91.4%) were performed by ≤13 weeks' gestation. Few abortions (7.3%) were performed between 14–20 weeks' gestation or at ≥21 weeks' gestation (1.4%). From 2002 to 2011, the percentage of all abortions performed at ≤8 weeks' gestation increased 6%. 
Leading up to the 40th anniversary of the Roe v. Wade Supreme Court decision in January 2013, a majority of Americans believed abortion should be legal in all or most cases, according to a poll by NBC News and the Wall Street Journal. As well, approximately 70% of respondents oppose Roe v. Wade being overturned, which is the highest percentage on this question since 1989. A poll by the Pew Research Center yielded similar results. Moreover, 48% of Republicans opposed overturning Roe, compared to 46% who supported overturning it.
Gallup notes that abortion attitudes are shifting. Gallup declared in May 2010 that more Americans identifying as "pro-life" is "the new normal", while also noting that there had been no increase in opposition to abortion. It suggested that political polarization may have prompted more Republicans to call themselves "pro-life". The terms "pro-choice" and "pro-life" do not always reflect a political view or fall along a binary; in one Public Religion Research Institute poll, seven in ten Americans described themselves as "pro-choice" while almost two-thirds described themselves as "pro-life". The same poll found that 56% of Americans were in favor of legal access to abortion in all or some cases.
|Date of poll||Pro-life||Pro-choice||Mixed / neither||Don't know what terms mean||No opinion|
|2011, May 5–8||45%||49%||3%||2%||2%|
|2010, March 26–28||46%||45%||4%||2%||3%|
|2009, November 20–22||45%||48%||2%||2%||3%|
|2009, May 7–10||51%||42%||-||0||7%|
|2008, September 5–7||43%||51%||2%||1%||3%|
Pew Research Center polling shows little change in views from 2008 to 2012; modest differences based on gender or age.

A January 2003 CBS News/New York Times poll examined whether Americans thought abortion should be legal or not, and found variations in opinion which depended upon party affiliation and the region of the country. The margin of error is +/- 4% for questions answered of the entire sample ("overall" figures) and may be higher for questions asked of subgroups (all other figures).
|Group||Generally available||Available, but with stricter limits than now||Not permitted|
A CNN/USA Today/Gallup poll in January 2003 asked about the legality of abortion by trimester, using the question, "Do you think abortion should generally be legal or generally illegal during each of the following stages of pregnancy?"  This same question was also asked by Gallup in March 2000 and July 1996. Polls indicates general support of abortion during the first trimester although support drops dramatically for abortion during the second and third trimester.

According to Gallup's long-time polling on abortion, the majority of Americans are neither strictly Pro-Life or Pro-Choice; it depends upon circumstances. Gallup polling from 1996 to 2009 consistently reveals that when asked the question, "Do you think abortions should be legal under any circumstances, legal only under certain circumstances, or illegal in all circumstances?", Americans repeatedly answer 'legal only under certain circumstances'. According to the poll, in any given year 48-57% say legal only under certain circumstances (for 2009, 57%), 21-34% say legal under any circumstances (for 2009, 21%), and 13-19% illegal in all circumstances (for 2009, 18%), with 1-7% having no opinion (for 2009, 4%).
"Do you think abortions should be legal under any circumstances, legal only under certain circumstances, or illegal in all circumstances?"
|Legal under any circumstances||Legal only under certain/few circumstances||Illegal in all circumstances||No opinion|
|2011 May 5–8||27%||49%||22%||3%|
|2009 Jul 17-19||21%||57%||18%||4%|
|2009 May 7–10||22%||53%||23%||2%|
|2008 May 8–11||28%||54%||18%||2%|
|2007 May 10–13||26%||55%||17%||1%|
|2006 May 8–11||30%||53%||15%||2%|
According to the aforementioned poll, Americans differ drastically based upon situation of the pregnancy, suggesting they do not support unconditional abortions. Based on two separate polls taken May 19–21, 2003, of 505 and 509 respondents respectively, Americans stated their approval for abortion under these various circumstances:
|Poll Criteria||Total||Poll A||Poll B|
|When the woman's life is endangered||78%||82%||75%|
|When the pregnancy was caused by rape or incest||65%||72%||59%|
|When the child would be born with a life-threatening illness||54%||60%||48%|
|When the child would be born mentally disabled||44%||50%||38%|
|When the woman does not want the child for any reason||32%||41%||24%|
Another separate trio of polls taken by Gallup in 2003, 2000, and 1996, revealed public support for abortion as follows for the given criteria:
|Poll criteria||2003 Poll||2000 Poll||1996 Poll|
|When the woman's life is endangered||85%||84%||88%|
|When the woman's physical health is endangered||77%||81%||82%|
|When the pregnancy was caused by rape or incest||76%||78%||77%|
|When the woman's mental health is endangered||63%||64%||66%|
|When there is evidence that the baby may be physically impaired||56%||53%||53%|
|When there is evidence that the baby may be mentally impaired||55%||53%||54%|
|When the woman or family cannot afford to raise the child||35%||34%||32%|
Gallup furthermore established public support for many issues supported by the Pro-Life community and opposed by the Pro-Choice community:
|Legislation||2003 Poll||2000 Poll||1996 Poll|
|A law requiring doctors to inform patients about alternatives to abortion before performing the procedure||88%||86%||86%|
|A law requiring women seeking abortions to wait 24 hours before having the procedure done||78%||74%||73%|
|Legislation||2005 Poll||2003 Poll||1996 Poll||1992 Poll|
|A law requiring women under 18 to get parental consent for any abortion||69%||73%||74%||70%|
|A law requiring that the husband of a married woman be notified if she decides to have an abortion||64%||72%||70%||73%|
An October 2007 CBS News poll explored under what circumstances Americans believe abortion should be allowed, asking the question, "What is your personal feeling about abortion?" The results were as follows:
|Permitted in all cases||Permitted, but subject to greater restrictions than it is now||Only in cases such as rape, incest, or to save the woman's life||Only permitted to save the woman's life||Never||Unsure|
"Partial-Birth abortion" is nomenclature for a procedure called intact dilation and extraction generally used by those who oppose the procedure. A Rasmussen Reports poll four days after the Supreme Court's opinion in Gonzales v. Carhart found that 40% of respondents "knew the ruling allowed states to place some restrictions on specific abortion procedures." Of those who knew of the decision, 56% agreed with the decision and 32% were opposed. An ABC poll from 2003 found that 62% of respondents thought partial-birth abortion should be illegal; a similar number of respondents wanted an exception "if it would prevent a serious threat to the woman's health." Additional polls from 2003 found between 47–70% in favor of banning this type of abortion and between 25–40% opposed.
Gallup has repeatedly queried the American public on this issue, as seen on its Abortion page:
|A law which would make it illegal to perform a specific abortion procedure conducted in the last six months (or second and/or third trimester) of pregnancy known by some opponents as a partial birth abortion, except in cases necessary to save the life of the mother||70%||63%||66%||64%||61%||61%||55%||57%|
The abortion debate has also been extended to the question of who pays the medical costs of the procedure, with some states using the mechanism as a way of reducing the number of abortions. The cost of an abortion varies depending on factors such as location, facility, timing, and type of procedure. In 2005, a nonhospital abortion at 10 weeks' gestation ranged from $90 to $1,800 (average: $430), whereas an abortion at 20 weeks' gestation ranged from $350 to $4,520 (average: $1,260). Costs are higher for a medical abortion than a first-trimester surgical abortion.
The Hyde Amendment is a federal legislative provision barring the use of federal Medicaid funds to pay for abortions except for rape and incest. The provision, in various forms, was in response to Roe v. Wade, and has been routinely attached to annual appropriations bills since 1976, and represented the first major legislative success by the pro-life movement. The law requires that states cover abortions under Medicaid in the event of rape, incest, and life endangerment. Based on the federal law:
Though members of both major political parties come down on either side of the issue, the Republican Party is often seen as being pro-life, since the official party platform opposes abortion and considers unborn children to have an inherent right to life. Republicans for Choice represents the minority of that party. In 2006 pollsters found that 9% of Republicans favor the availability of abortion in most circumstances. Of Republican National Convention delegates in 2004, 13% believed that abortion should be generally available, and 38% believed that it should not be permitted. The same poll showed that 17% of all Republican voters believed that abortion should be generally available to those who want it, while 38% believed that it should not be permitted.
The Democratic Party platform considers abortion to be a woman's right. Democrats for Life of America represents the minority of that party. In 2006 pollsters found that 74% of Democrats favor the availability of abortion in most circumstances. However, a Zogby International poll in 2004 found that 43% of all Democrats believed that abortion "destroys a human life and is manslaughter." Of Democratic National Convention delegates in 2004, 75% believed that abortion should be generally available, and 2% believed that abortion should not be permitted. The same poll showed that 49% of all Democratic voters believed that abortion should be generally available to those who want it, while 13% believed that it should not be permitted.
The Green Party of the United States supports abortion as a woman's right.
The Libertarian Party platform (2012) states that "government should be kept out of the matter, leaving the question to each person for their conscientious consideration." Abortion is a contentious issue among Libertarians, and the Maryland-based organization Libertarians for Life opposes the legality of abortion in most circumstances.
In the United States the abortion issue has become deeply politicized: in 2002, 84% of state Democratic platforms supported the right to having an abortion while 88% of state Republican platforms opposed it. This divergence also led to Christian Right organizations like Christian Voice, Christian Coalition and Moral Majority having an increasingly strong role in the Republican Party. This opposition has been extended under the Foreign Assistance Act: in 1973 Jesse Helms introduced an amendment banning the use of aid money to promote abortion overseas, and in 1984 the Mexico City Policy prohibited financial support to any overseas organization that performed or promoted abortions. The "Mexico City Policy" was revoked by President Bill Clinton and subsequently reinstated by President George W. Bush. President Barack Obama overruled this policy by Executive Order on January 23, 2009.
The official platforms of the major political parties in the US are as follows:
The risk of death due to legal abortion has fallen considerably since legalization in 1973, due to increased physician skills, improved medical technology, and earlier termination of pregnancy. From 1940 through 1970, deaths of pregnant women during abortion fell from nearly 1,500 to a little over 100. According to the Centers for Disease Control, the number of women who died in 1972 from illegal abortion was thirty-nine (39). In 1960, Dr. Mary Calderone, a former director of Planned Parenthood, said:
|“||Abortion is no longer a dangerous procedure. This applies not just to therapeutic abortions as performed in hospitals but also to so-called illegal abortions as done by physician. In 1957 there were only 260 deaths in the whole country attributed to abortions of any kind ...90 percent of all illegal abortions are presently being done by physicians ...Whatever trouble arises usually arises from self-induced abortions, which comprise approximately 8 percent, or with the very small percentage that go to some kind of non-medical abortionist...||”|
The Roe effect is an hypothesis which suggests that since supporters of abortion rights cause the erosion of their own political base by having fewer children, the practice of abortion will eventually lead to the restriction or illegalization of abortion. The legalized abortion and crime effect is another controversial theory that posits legal abortion reduces crime, because unwanted children are more likely to become criminals.
Since Roe v Wade, there have been numerous attempts to reverse the decision. In the 2011 election season, Mississippi placed an amendment on the ballot that redefine how the state viewed abortion. The personhood amendment defined personhood as "every human being from the moment of fertilization, cloning or the functional equivalent thereof". If passed, it would have been illegal to get an abortion in the state.
On July 11, 2012, a Mississippi federal judge ordered an extension of his temporary order to allow the state's only abortion clinic to stay open. The order will stay in place until U.S. District Judge Daniel Porter Jordan III can review newly drafted rules on how the Mississippi Department of Health will administer a new abortion law. The law in question came into effect on July 1.
Although it is uncommon, women sometimes give birth in spite of an attempted abortion. Reporting of livebirth after attempted abortion may not be consistent from state to state, but 38 were recorded in one study in upstate New York in the two-and-a-half years before Roe v. Wade. Under the Born-Alive Infants Protection Act of 2002, medical staff must report live birth if they observe any breathing, heartbeat, umbilical cord pulsation, or confirmed voluntary muscle movement, regardless of gestational age. To ensure the success of the abortion procedure, doctors are advised to induce fetal death before abortion procedures after 21 weeks gestation, especially when performing induced labor abortion.
Some 42 facilities were originally invited to participate in the study; these include six at which a relatively large number of late abortions (those at 16 or more weeks' gestation) were performed.
At every gestational age, elective abortion is safer for the mother than carrying a pregnancy to term.
Live birth following medical termination of pregnancy before 21+6 weeks of gestation is very uncommon. Nevertheless, women and their partners should be counselled about this unlikely possibility and staff should be trained to deal with this eventuality. Instances of recorded live birth and survival increase as gestation at birth extends from 22 weeks. In accordance with prior RCOG guidance, feticide should be routinely offered from 21+6 weeks of gestation.Where the fetal abnormality is not compatible with survival, termination of pregnancy without prior feticide may be preferred by some women. In such cases, delivery management should be discussed and planned with the parents and all health professionals involved and a written care plan agreed before termination takes place. Where the fetal abnormality is not lethal and termination of pregnancy is being undertaken after 22 weeks of gestation, failure to perform feticide could result in live birth and survival, an outcome that contradicts the intention of the abortion. In such situations, the child should receive the neonatal support and intensive care that is in the child's best interest and its condition managed within published guidance for neonatal practice.
...Additionally, a significantly higher proportion of women in the vaginal misoprostol group, and a marginally higher proportion of those in the oral misoprostol group, than of those in the intra-amniotic prostaglandin group had a live birth (20%, 15% and 5%, respectively)....
