Late last year I noticed that Buckeye Firearms Association was publishing concealed carry statistics for Ohio. As an example here is a recent post about the 2016 statistics, Annual Attorney General Summary on Concealed Carry: 2016 marks busiest year on record. Although my calculations of the total number of valid licenses did not match up as closely as I would like, I will gladly defer to their report. There are a lot of people with concealed carry licenses. My favorite quote from their report is:

For the person without a CHL, what this means is that anytime they look around and see 14 other people, odds are that one of them has a CHL. Concealed carry is mainstream, common sense and is close to most people on a daily basis. It works so well that most people are blissfully unaware that anyone else is carrying a gun.
