Abortion may prevent the birth of “unwanted” children, who would have relatively small investments in human capital and a higher probability of crime. On the other hand, some research suggests that legalizing abortion increases out-of-wedlock births and single parent families, which implies the opposite impact on investments in human capital and thus crime. The question is: what is the net impact? We find evidence that legalizing abortion increased murder rates by around about 0.5 to 7 percent. Previous estimates are shown to suffer from not directly linking the cohorts who are committing crime with whether they had been born before or after abortion was legal.

Law professors John R. Lott, Jr. of Yale Law School and John E. Whitley of the University of Adelaide found that legalizing abortion increased murder rates by up to seven percent. They concluded that legalizing abortion is a contributing factor to the great increase in out‑of‑wedlock births and single parent families, which in turn contribute to increased crime rates. Since 1970, the percentage of single‑parent households in the United States has nearly tripled, from 11 percent to 32 percent, and the percentage of out‑of‑wedlock births has nearly quadrupled, from 11 percent to 43 percent of all children.7 Children born out-of-wedlock and raised by only one parent have a significantly higher incidence of crime.

There are many other fundamental problems with the conclusion that legalized abortion leads to a decrease in crime.

Statistician David Murray confirmed that young males between the ages of 17 and 25 commit the majority of crimes. However, if abortion had reduced crime, the crime rates in the United States would have dropped first among young people. They did not. Instead, the number of crimes committed by older people dropped first. Nearly 60% of the decline in murder since 1990 involved killers aged 25 and older — who were born before Roe v. Wade.8

Murray also found that other nations with high abortion rates showed a large increase in crime about eighteen years after they legalized abortion. For example, in Great Britain, which legalized abortion in 1968, violent crime has been rising steeply since about 1985 ― exactly when it should have been declining, according to the Donohue‑Levitt thesis. Additionally, Russia, with the highest abortion rate on earth, has experienced a tidal wave of every kind of violent crime following the breakup of the Soviet Union.9

FBI statistics showed that the murder rate in 1993 for 14‑ to 17‑year‑olds in the USA (born in the years 1975‑1979, which had very high abortion rates) was 3.6 times higher than that of kids who were the same age in 1984 (who were born in the pre‑legalization years of 1966‑1970). Additionally, since Black women were having abortions at a much higher rate than White women, we should have expected the murder rate among Black youth to have declined beginning in about 1991. Instead, it increased more than five hundred percent from 1984 to 1993.10

Finally, the huge increase in violent crime that peaked in 1991 and then began to decline is more closely related to the crack epidemic, not abortion. The Donohue‑Levitt study confirms that the crime rate rose and fell exactly where crack cocaine was most easily available ― in the large cities and among young Black males.11 This is also confirmed by the rise in crime during the time period 1984 to 1991, after a decline from 1980 to 1984. If abortion were the primary cause of a decline in violent crime, the crime rate would have been relatively stable during the time period 1980 to 1991.

For decades, evidence has existed showing abortion contributes to a rise in child abuse. Now a new study by a post-abortion research institute and Bowling Green State University professors finds that women who have abortions are more likely to abuse their children.

Published in the medical journal Acta Paediatrica, the study found that women who have had abortions are 2.4 times more likely to physically abuse their children. Pro-life advocates say it proves the need for providing women with post-abortion counseling to help deal with the emotional trauma of the abortion.

[…]The authors suggested that “emotional difficulties and unresolved grief responses” from pregnancy loss, whether voluntary or involuntary, could have a negative impact on women’s mental health and lead to unhealthy parenting responses.

According to the Illinois-based Elliot Institute, which released information about the study’s findings, prior surveys “have linked pregnancy loss to an increase in grief reactions, anxiety, depression, sleep disturbances, and symptoms of post-traumatic stress disorder, all of which can have a negative impact on parent/child relationships.”

The post-abortion research group also points to a 2002 study published in the Journal of Child Psychiatry and Psychology that found abortion has been linked to an increase in substance abuse and thoughts of suicide, which could also contribute to child abuse.

The new study also found that women who had more than one miscarriage or stillbirth were more likely to engage in child abuse than women who had just one. However, women who had abortions were more likely to abuse their children whether they had one or more than one abortion.

“Regardless of the specific mechanisms at play, maternal history of one induced abortion does appear to be a marker for increased risk of physical abuse,” the authors concluded.
