Be Careful What You Wish For

4/20/18 Reason:

Many people who support gun control are angry that the federal Centers for Disease Control (CDC) are not legally allowed to use money from Congress to do research whose purpose is "to advocate or promote gun control." (This is not the same as doing no research into gun violence, though it seems to discourage many potential recipients of CDC money.)

But in the 1990s, the CDC itself did look into one of the more controversial questions in gun social science: How often do innocent Americans use guns in self-defense, and how does that compare to the harms guns can cause in the hands of violent criminals?

Florida State University criminologist Gary Kleck conducted the most thorough previously known survey data on the question in the 1990s. His study, which has been harshly disputed in pro-gun-control quarters, indicated that there were more than 2.2 million such defensive uses of guns (DGUs) in America a year.

Now Kleck has unearthed some lost CDC survey data on the question. The CDC essentially confirmed Kleck's results. But Kleck didn't know about that until now, because the CDC never reported what it found.

Kleck's new paper—"What Do CDC's Surveys Say About the Frequency of Defensive Gun Uses?"—finds that the agency had asked about DGUs in its Behavioral Risk Factor Surveillance System in 1996, 1997, and 1998.

Those polls, Kleck writes,

are high-quality telephone surveys of enormous probability samples of U.S. adults, asking about a wide range of health-related topics. Those that addressed DGU asked more people about this topic than any other surveys conducted before or since. For example, the 1996 survey asked the DGU question of 5,484 people. The next-largest number questioned about DGU was 4,977 by Kleck and Gertz (1995), and sample sizes were much smaller in all the rest of surveys on the topic (Kleck 2001).

Shock of shocks, they gave similar numbers to the oft-criticized Kleck survey numbers.  Probably why they were not published.
