"Of course, the most obvious effect of the abortion decisions was the increase in abortions. Although the biggest percentage increase of abortions in America actually occurred before Roe, after thirteen states had legalized abortion in certain circumstances between 1967 and 1970, the nationwide legalization in January 1973 significantly increased the number of abortions performed in America. In 1972, the year before Roe, about 550,000 legal abortions were recorded. After Roe, abortions increased, reaching an annual high of 1.6 million in 1992, before declining to 1.2 million in 2006."
