The Impact of Legalized Abortion on Crime
提供证据表明，合法堕胎对近年犯罪率下降有显著贡献，犯罪率在堕胎合法化约18年后开始下降，1970年允许堕胎的五个州犯罪率下降早于全国，高堕胎率州在1990年代犯罪降幅更大，合法堕胎可解释高达50%的近期犯罪下降。
We offer evidence that legalized abortion has contributed significantly to recent crime reductions. Crime began to fall roughly eighteen years after abortion legalization. The five states that allowed abortion in 1970 experienced declines earlier than the rest of the nation, which legalized in 1973 with Roe v. Wade. States with high abortion rates in the 1970s and 1980s experienced greater crime reductions in the 1990s. In high abortion states, only arrests of those born after abortion legalization fall relative to low abortion states. Legalized abortion appears to account for as much as 50 percent of the recent drop in crime.
