Legalised Abortion Reduces Crime
A study of the 30 - 40% fall of the american crime rate from 1991 to 1999 has been attributed to the legalisation of abortion 18 yrs earlier. The idea is that the number of unwanted and thus neglected babies/children was reduced. Being unwanted and neglected often leads children to problems including crime.
First, we demonstrate that crime rates began to fall 18 years after the landmark Supreme Court decision Roe vs. Wade legalized abortion across the nation, just the point at which babies born under legalized abortion would be reaching the peak adolescent crime years. In my opinion, this is the weakest of our four data analyses. In a simple time series, many factors are negatively correlated with crime. Furthermore, the world is a complicated place and it would be simplistic to believe that legalized abortion could overpower all other social determinants of crime.
Second, we show that the five states that legalized abortion in 1970--three years before Roe vs. Wade--saw crime begin to decrease roughly three years earlier than the rest of the nation. This is a bit more convincing to me but still far from conclusive.
Third, we demonstrate that states with high abortion rates in the mid-1970s have had much greater crime decreases in the 1990s than states that had low abortion rates in the 1970s. This relationship holds true even when we take into account changes in the size of prison populations, number of police, poverty rates, measures of the economy, changes in welfare generosity, and other changes in fertility. This is the evidence that really starts to be convincing, in my opinion.
