Abortion rates declined significantly across most developed regions between 1990 and 2014. However, during the same period, they remained largely unchanged in developing regions. The findings come from a new study by the Guttmacher Institute and the World Health Organization (WHO). It found that between 1990 and 2014, the overall number of abortions per 1,000 women of childbearing age (15–44 years old) in developed countries dropped from 46 to 27, while in developing countries, it changed little, from 39 to 37, a non-significant difference. The study’s findings appear in an article, “Abortion incidence between 1990 and 2014: global, regional, and subregional levels and trends,” by Gilda Sedgh et al., published today in The Lancet.
