An unpublished study from the CDC states that Guns are used in self-defense over 2 million times per year.
In 1996, 1997, and 1998, the Centers for Disease Control and Prevention (CDC) conducted large-scale national surveys asking about defensive gun use (DGU). They never released the findings, or even acknowledged they had studied the topic. I obtained the unpublished raw data and computed the prevalence of DGU. CDC’s findings indicated that an average of 2.46 million U.S. adults used a gun for self-defense in each of the years from 1996 through 1998 – almost exactly confirming the estimate for 1992 of Kleck and Gertz (1995). Possible reasons for CDC’s suppression of these findings are discussed.
