The Crime Prevention Research Center (CPRC) has released a report that shows that during the 2007-2015 time period, the percentage of adults with permits to carry concealed firearms rose 190 percent. At the same time, violent crime fell by 18 percent. The report noted that 2015 was the cap on the period in question because it is “the last full year that crime data is available.”
According to the CPRC report, during the 2007 to 2015 period, “murder rates fell from 5.6 [per 100,000] to 4.9 per 100,000. This represents a 12.5% drop.” During the same period, according to the report, “overall violent crime fell by 18 percent.” These figures coincide with a an increase of 190 percent increase in “the percentage of adults with permits.”
The same CPRC report showed that the number of concealed carry permit holders “grew by a record 1.83 million” in 2016. That represents an increase over the previous record of 1.73 million, which was set in 2015. The report said that this means that 6.53 percent of adults in the country have carry permits. It noted that “outside the restrictive states of California and New York, about 8% of the adult population has a permit.” There are 11 states where more than 10 percent of adults have carry permits. In Alabama, for example, 20 percent of adults have permits, while Indiana, 15.8 percent of adults have permits.
The 61-page study was drafted by researcher John R. Lott Jr. The abstract of the paper reads:
“There are now over 16.3 million permit holders, a record 1.83 million increase in permits since last July. Nationwide, 6.5% adults have a concealed handgun permit. Outside of California and New York, 8 percent of adults have a permit. Permits for women and blacks are increasing much faster than they are for men and whites. There are also significant differences in not only the number of permits issued but also who gets them when politicians have discretion in granting them. Los Angeles County provides a vivid example of how women and Hispanics are given few permits when politicians decided who can defend themselves. We also provide evidence that death threats don't let people get permits for protection and how incredibly law-abiding permit holders are and how crime rates have changed in the states that have had the largest increases in concealed handgun permits.”
The study read:
“Regression estimates show a significant association between increased permit ownership and drops in murder and violent crime rates. Each one percentage point increase in rates of permit-holding is associated with a roughly 2.5 percent drop in the murder rate. This holds true even after accounting for incarceration rates, the number of police per capita, and other demographics.”
