Abortion, when induced in the developed world in accordance with local law, is among the safest procedures in medicine.[1] However, unsafe abortions result in approximately 70,000 maternal deaths and 5 million hospital admissions per year globally.[2] An estimated 44 million abortions are performed globally each year, with slightly under half of those performed unsafely.[3] The incidence of abortion has stabilized in recent years,[3] having previously spent decades declining as access to family planning education and contraceptive services increased.[4] Forty percent of the world's women have access to induced abortions (within gestational limits).[5]
Induced abortion has a long history and has been facilitated by various methods including herbal abortifacients, the use of sharpened tools, physical trauma, and other traditional methods. Contemporary medicine utilizes medications and surgical procedures to induce abortion. The legality, prevalence, cultural and religious status of abortion vary substantially around the world. Its legality can depend on specific conditions such as incest, rape, fetal defects, a high risk of disability, socioeconomic factors or the mother's health being at risk. In many parts of the world there is prominent and divisive public controversy over the moral, ethical, and legal issues of abortion.
Abortion rates also vary depending on the stage of pregnancy and the method practiced. In 2003, the Centers for Disease Control and Prevention (CDC) reported that 26% of abortions in the United States were known to have been obtained at less than 6 weeks' gestation, 18% at 7 weeks, 15% at 8 weeks, 18% at 9
