Abortion in the United Kingdom is de facto available under the terms of the Abortion Act 1967 in Great Britain and the Abortion (No.2) Regulations 2020 in Northern Ireland. The procurement of an abortion remains a criminal offence in Great Britain under the Offences Against the Person Act 1861, although the Abortion Act provides a legal defence for both the pregnant woman and her doctor in certain cases. Although a number of abortions did take place before the 1967 Act, there have been around 10 million abortions in the United Kingdom. Around 200,000 abortions are carried out in England and Wales each year and just under 14,000 in Scotland; the most common reason cited under the ICD-10 classification system for around 98% of all abortions is "risk to woman's mental health."
Public opinion on abortion has changed dramatically in Ireland. Abortion in Ireland is regulated by the Health Act 2018. Abortion is permitted in Ireland during the first twelve weeks of pregnancy, and later in cases where the pregnant woman's life or health is at risk, or in the cases of a fatal foetal abnormality. Abortion services commenced on 1 January 2019, following its legalisation by the aforementioned Act, which became law on 20 December 2018. Previously, the 8th Constitutional Amendment had given the life of the unborn fetus the same value as that of its mother, but the 36th constitutional amendment, approved by referendum in May 2018, replaced this with a clause permitting the Oireachtas (parliament) to legislate for the termination of pregnancies.
In the United States, abortion is a divisive issue in politics and culture wars, though a majority of Americans support access to abortion. Abortion laws vary widely from state to state.
The abortion debate is a longstanding and contentious discourse that touches on the moral, legal, medical, and religious aspects of induced abortion. In English-speaking countries, the debate has two major sides, commonly referred to as the "pro-choice" and "pro-life" movements. Generally, supporters of pro-choice argue for the right to choose to terminate a pregnancy. They take into account various factors such as the stage of fetal development, the health of the woman, and the circumstances of the conception. By comparison, the supporters of pro-life generally argue that a fetus is a human being with inherent rights and intrinsic value, and thus, cannot be overridden by the woman's choice or circumstances and that abortion is morally wrong in most or all cases. Both the terms pro-choice and pro-life are considered loaded words in mainstream media, which tend to prefer terms such as "abortion rights" or "anti-abortion" as more neutral and avoidant of bias.
Late termination of pregnancy, also referred to politically as third trimester abortion, describes the termination of pregnancy by inducing labor during a late stage of gestation. In this context, late is not precisely defined, and different medical publications use varying gestational age thresholds. As of 2015, in the United States, more than 90% of abortions occur before the 13th week, 1.3% take place after the 21st week, and less than 1% occur after 24 weeks.
Abortion laws vary widely among countries and territories, and have changed over time. Such laws range from abortion being freely available on request, to regulation or restrictions of various kinds, to outright prohibition in all circumstances. Many countries and territories that allow abortion have gestational limits for the procedure depending on the reason; with the majority being up to 12 weeks for abortion on request, up to 24 weeks for rape, incest, or socioeconomic reasons, and more for fetal impairment or risk to the woman's health or life. As of 2022, countries that legally allow abortion on request or for socioeconomic reasons comprise about 60% of the world's population. In 2024, France became the first country to explicitly protect abortion rights in its constitution, while Yugoslavia implicitly inscribed abortion rights in its constitution in 1974.
Abortion in Australia is legal. There are no federal abortion laws, though decriminalisation of the procedure has been enacted in all jurisdictions. Access to abortion varies between the states and territories: Surgical abortions are readily available on request within the first 22 to 24 weeks of pregnancy in most jurisdictions, and up to 16 weeks in Tasmania. Later-term abortions can be obtained with the approval of two doctors, although the Australian Capital Territory only requires a single physician's approval.
Abortion in Sweden was first legislated by the Abortion Act of 1938. This stated that an abortion could be legally performed in Sweden upon medical, humanitarian, or eugenical grounds. That is, if the pregnancy constituted a serious threat to the woman's life, if she had been impregnated by rape, or if there was a considerable chance that any serious condition might be inherited by her child, she could request an abortion. The law was later augmented in 1946 to include socio-medical grounds and again in 1963 to include the risk of serious fetal damage. A committee investigated whether these conditions were met in each individual case and, as a result of this prolonged process, abortion was often not granted until the middle of the second trimester. As such, a new law was created in 1974, stating that the choice of an abortion is entirely up to the woman until the end of the 18th week.
Chile's abortion laws have evolved significantly in recent years. Since 2017, abortion has been legal under three specific circumstances: when the woman's life is at risk, in cases of rape, and in instances of severe fetal malformations. Despite these legal changes, some medical professionals refuse to perform abortions, particularly in rape cases.
Abortion in Brazil is a crime, with penalties of one to three years of imprisonment for the recipient of the abortion, and one to four years of imprisonment for the doctor or any other person who performs the abortion on someone else. In three specific situations in Brazil, induced abortion is not punishable by law: in cases of risk to the pregnant woman’s life; when the pregnancy is the result of rape; and if the fetus is anencephalic. In these cases, the Brazilian government provides the abortion procedure free of charge through the Sistema Único de Saúde. This does not mean that the law regards abortion in these cases as a right, but only that women who receive abortions under these circumstances, and the doctors, will not be punished. The punishment for a woman who performs an abortion on herself or consents to an abortion performed by another outside these legal exceptions is one to three years of detention. The base penalty for a third party that performs an illegal abortion with the consent of the patient, ranges from one to four years of detention, with the possibility of increase by a third if the woman comes to any physical harm, and can be doubled if she dies. Criminal penalties fixed at four years or less can be converted to non-incarceration punishments, such as community service and compulsory donation to charity.
The abortion–breast cancer hypothesis posits that having an induced abortion can increase the risk of getting breast cancer. This hypothesis is at odds with mainstream scientific opinion and is rejected by major medical professional organizations; despite this, it continues to be widely propagated as pseudoscience, typically in service of an anti-abortion agenda.
Societal attitudes towards abortion have varied throughout different historical periods and cultures. One manner of assessing such attitudes in the modern era has been to conduct opinion polls to measure levels of public opinion on abortion.
Abortion has been legal in India under various circumstances with the introduction of the Medical Termination of Pregnancy (MTP) Act, 1971. The Medical Termination of Pregnancy Regulations, 2003 were issued under the Act to enable women to access safe and legal abortion services.
Abortion in Poland is illegal except in cases where the pregnancy is a result of a criminal act or when the woman's life or health is in danger. The last change in the Act on Pregnancy Planning of the Republic of Poland took place on 27 January 2021, when publication of the judgment of the Polish Constitutional Tribunal in the Dziennik Ustaw RP took place.
Abortion in Colombia is freely available on request up to the 24th week of pregnancy, due to a ruling by the Constitutional Court on February 21, 2022. Later in pregnancy, it is only allowed in cases of risk of death to the pregnant woman, fetal malformation, or rape, according to a Constitutional Court ruling in 2006.
Abortion in Denmark was fully legalized on 1 October 1973, allowing the procedure to be done electively if a woman's pregnancy has not exceeded its 12th week. Under Danish law, the patient must be over the age of 18 to decide on an abortion alone; parental consent is required for minors, except in special circumstances. An abortion can be performed after 12 weeks if the woman's life or health are in danger. A woman may also be granted an authorization to abort after 12 weeks if certain circumstances are proved to be present.
Abortion in Serbia was legalized in its current form on October 7, 1977. Abortion on demand is available for women whose pregnancies have not exceeded the tenth week, and in the case of risk to life or health of woman, or when the pregnancy has resulted from a sex offence, or in case of fetal impairment up to twenty weeks. Minors under 16 require parental consent before undergoing an abortion.
Abortion-rights movements, also self-styled as pro-choice movements, are movements that advocate for legal access to induced abortion services, including elective abortion. They seek to represent and support women who wish to terminate their pregnancy without fear of legal or social backlash. These movements are in direct opposition to anti-abortion movements.
Abortion in Thailand is legal and available on-request up to 20 weeks of pregnancy. Abortion has been legal up to at least 12 weeks of pregnancy since 7 February 2021. Following a 2020 ruling of the Constitutional Court which declared a portion of the abortion statutes unconstitutional, the Parliament removed first-term abortion from the criminal code. Once strict, over time laws have been relaxed to take into account high rates of teen pregnancy, women who lack the means or will to raise children, and the consequences of illegal abortion.
Abortion in South Korea was decriminalized, effective 1 January 2021, by a 2019 order of the Constitutional Court of Korea. It is currently legal throughout pregnancy, as no new law has been enacted. Thus there are no gestational limits or other restrictions.
