A cross-cultural history of abortion.

Abortion is a universal phenomenon, occurring throughout recorded history and at all levels of societal organization. Techniques are highly varied, as are the circumstances under which it is practised. The status of and attitudes towards abortion in Western civilization are variable and have, in most cases, been changing. As of 1982, 10% and 18% of the world's population respectively, lived in countries where abortion was totally prohibited or where it was permitted only to save the mother's life. In the USA, various national surveys indicate liberalization of public attitudes towards pregnancy termination between 1965 and the years immediately following the Roe v. Wade Supreme Court decision (1973) which legalized abortion. More recent polls demonstrate little attitudinal change since 1972-1973: between 80% and 90% of Americans approve of abortion in the case of poor health, a seriously defective fetus, or rape, and between 40% and 50% indicate approval for all other reasons as well. Only 10% of the American population would like to see abortion prohibited under all circumstances. Sociodemographic analyses indicate that individuals who disapprove of abortion differ from those who approve of its availability in that they are more likely to be Roman Catholic or fundamentalist Protestant; are, in general, more strongly committed to organized religion; are on the traditional/conservative end of the spectrum with regard to women's role in life, premarital sex, sex education and civil liberties; and tend to have achieved a relatively low educational level. 'Pro-life' and 'pro-choice' activists tend to be women who are completely different from one another in sociodemographic characteristics and in overall values, particularly as these relate to traditional versus modern female roles.
