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.
