Summary: Legalization of Abortion Correlates to
Significant Increase in Murder Rates
Previous research claimed that legalized
abortion accounted for a large part of the drop in murder rates
between 1991 and 1997. Subsequent research demonstrates that, to the
contrary, legalizing abortion was associated with a statistically
significant increase in murder rates.
In 2001, Donohue and
Levitt suggested that legalized abortion was responsible for as much
as half of the overall reduction in crime rates during the 1990s,
including significant reduction in murder rates. More recent
research found that while many factors reduce murder rates, abortion
is not one of them. By using homicide reports rather than arrest
reports as well as other measures to ensure accuracy, researchers
determined that in more than 6,000 regressions, only one implied
even a small reduction in the murder rates. To the contrary,
estimates implied significant increases in murder rates as well as
total annual victimization costs as a result of abortion.
