More Guns, Less Crime

More Guns, Less Crime is a book by John Lott that says violent crime rates go down when states pass “shall issue” concealed carry laws. He presents the results of his statistical analysis of crime data for every county in the United States during 29 years from 1977 to 2005.

Each edition of the book was refereed by the University of Chicago Press. The book examines city, county and state level data from the entire United States and measures the impact of 13 different types of gun control laws on crime rates. The book expands on an earlier study published in 1997 by Lott and his co-author David Mustard in The Journal of Legal Studies and by Lott and his co-author John Whitley in The Journal of Law and Economics, October 2001.
