The Centers for Disease Control and Prevention (CDC) found that the US abortion rate fell 26% between 2006 and 2015 to reach an all-time low. Further, the national abortion ratio–which weighs abortions against live births–also declined to record lows. In 2005, 233 abortions occurred for every 1,000 live births. In 2015, officials documented only 188 abortions per 1,000 live births.
According to other research, America’s abortion rate has fallen concurrently with global abortion rates. Across Europe and North America, infanticide has become gradually less prevalent in developed nations. The trend extends back to the 1990s: during that decade, 45 out of every 1,000 women aged 15 to 44 had an abortion. By the early 2010s, just 27 out of every 1,000 women obtained abortions in developed countries.
To explain the international decline in abortion rates, researchers point to several factors, including improved access to contraceptives, new pro-life legislation, and changing attitudes among millenials.
More restrictive abortion laws, for example, have reduced the incidence of infanticide: Globally, 39% of women of reproductive age cannot terminate their pregnancies, because no abortion clinics operate nearby.
Further, during the 1970s and 1980s, older pro-lifers in the United States significantly outnumbered their younger counterparts. Today, however, young people in the US express greater support for pro-life measures than older generations.
A 2017 Quinnipiac poll revealed that Americans aged 18 to 34 were more likely than older citizens to favor a 20-week abortion ban. Rasmussen’s 2013 study on the same topic reached similar conclusions.
