Below is the second of four parts of a 1999 debate in Slate between U. of Chicago economist Steven D. Levitt, co-author of the 2005 bestseller Freakonomics: A Rogue Economist Explores the Hidden Side of Everything, and myself, Steve Sailer. We discussed Levitt’s most celebrated theory: Did the legalization of abortion in 1969-1973 cause the crime rate to fall? 
I’ve decided to host this debate on my website because it is of some modest degree of historical importance as the first airing of one of the longer-running social science controversies of the 21st Century, and because Slate  deleted our names from their posting of it during a website reorganization. Several years ago, Slate  promised to restore our names, but hasn’t done so yet. The absence of our names on Slate  has made it hard for interested readers to find this using search engines.


Does Abortion Prevent Crime?

Part 2 of a 4-part debate between Steven D. Levitt and Steve Sailer

Complete debate: Part 1 (Levitt);   Part 2 (Sailer);   Part 3 (Levitt);   Part 4 (Sailer)
By Steve Sailer

Your open-minded search for the truth, no matter how disturbing it may turn out to be, epitomizes the scientific ideal. Your study of abortion and crime is exactly what the social sciences need more of: courageous, hard-headed inquiries into the big topics that everybody else is afraid to touch. Even more impressive is your behavior since the controversy started. (Some background for readers: On Aug. 15, I circulated a critique of Steven Levitt and John Donohue’s theory that legalized abortion reduced crime to the Human Biodiversity Discussion Group. A member passed it on to Steven, and despite his being deluged with media requests, he wrote to thank me for my criticisms. We then started up an e-mail exchange; this Slate “Dialogue” is its public continuation.)

With luck, I’ll have room in my next message to respond to your important questions about how to make public and academic discourse less moralistic and more realistic. (Short answer: Junk political correctness.) Today I’ll stick to the empirical issues. The problem with your abortion/reduced-crime theory is not that it encourages abortion or eugenic reasoning or whatever, but that it’s largely untrue. Your biggest methodological mistake was to focus on the crime rates only in 1985 and 1997. Thus, you missed the 800-pound gorilla of crime trends: the rise and fall of the crack epidemic during the intervening years. 

Here’s the acid test. Your logic implies that the babies who managed to get born in the ’70s should have grown up to be especially law-abiding teens in the early ’90s. Did they?

Not exactly. In reality, they went on the worst youth murder spree in American history. According to FBI statistics, the murder rate for 1993’s crop of 14- to 17-year-olds (who were born in the high-abortion years of 1975 to 1979) was a horrifying 3.6 times that of the kids who were 14 to 17 years old in 1984 (who were born in the pre-legalization years of 1966 to 1970). (Click here to see the graph.) In dramatic contrast, over the same time span the murder rate for those 25 and over (all born before legalization) dropped 6 percent.

Your model would also predict that the recent decline in crime should have shown up first among the youngest, but the opposite was true. The murder rate for 35- to 49-year-olds has been falling since the early ’80s, and for 25- to 34-year-olds since 1991, but the two most homicidal years for 14- to 17-year-olds were 1993 and 1994.

The dubiousness of your theory becomes even more obvious when we break down this post-Roe vs. Wade generation by race.

Now, you say that your theory isn’t “about race,” but simply about the greater likelihood that “unwanted” babies will grow up to be bad guys. That correlation sounds plausible. Still any realistic theory about abortion and crime must deal with the massive correlation between violence and race. As you note, African-Americans have three times the abortion rate of whites. You don’t mention, however, that, as Janet Reno’s Justice Department flatly states that “blacks are 8 times more likely than whites to commit homicide.” Therefore, blacks commit more murders than whites in total as well as per capita.

So, let’s look at just black males born in 1975 to 1979. Since their mothers were having abortions at three times the white rate, that should have driven down their youth murder rate. Instead, from 1984 to 1993 the black male youth homicide rate grew an apocalyptic 5.1 times. (Click here to see graph.) This black juvenile rate also grew relative to the white juvenile murder rate, from five times worse in 1984 to 11 times worse in 1993.

Why, then, is this generation born in 1975 to 1979 now committing relatively fewer crimes as it ages? It makes no sense to give the credit to abortion, which so catastrophically failed to keep them on the straight and narrow when they were juveniles. Instead, the most obvious explanation is the ups and downs of the crack business, which first drove violent crime up in the late ’80s and early ’90s, then drove it down in the mid and late ’90s. That’s why the crime rate has fallen fastest exactly where it had previously grown fastest as a result of crack–in the biggest cities (e.g., New York) and among young black males. This generation born right after legalization is better behaved today in part because so many of its bad apples are now confined to prisons, wheelchairs, and coffins. For example, over the last two decades the U.S. has doubled the number of black males in prison, to nearly 1 million.

More encouragingly, the biggest decline in murder from 1993 to 1997 was among the newest generation of black males aged 14 to 17. These kids born mostly in the early ’80s survived abortion levels similar to those faced by the crime-ridden 1975-to-1979 generation. Yet, their murder rate in 1997 was less than half that of the 14- to 17-year-olds of 1993. Seeing their big brothers gunned down in drive-by shootings and their big sisters becoming crack whores may have scared them straight.

Admittedly, it’s still theoretically possible that without abortion the black youth murder rate would have, say, sextupled instead of merely quintupling. Still, there’s a more interesting question: Why did the places with the highest abortion rates in the ’70s (e.g., NYC and Washington D.C.) tend to suffer the worst crack-driven crime waves in the early ’90s?

To read more on this topic, see Steve Sailer’s 2005 posting after The Economist and the Wall Street Journal revealed that an attempted replication of Levitt’s state-level analysis by Boston Fed economists Christopher Foote and Christopher Goetz discovered that Levitt had made a fatal error in his computer code, which explains why Levitt’s state-level findings didn’t match my national-level analysis in 1999.
