Movato Real Estate has compiled some interesting data that compared gun ownership in the 50 states with gun ownership in other countries using the methodology outlined below:
We started with a research group in Switzerland called Small Arms Survey and its report “Small Arms Survey 2007: Guns and the City.” Among other things, it estimated gun-ownership numbers for 178 countries, including the United States (which it estimates has about 270 million guns).
We then took the estimate of 88.8 guns per 100 people for the U.S.—which, seven years later, is likely higher—and used it to calculate each state’s estimated gun ownership, based on state populations from the U.S. Census Bureau’s 2010 survey. (Of course, gun-ownership density varies throughout the country, but this number gave us a easy way to come up with comparable figures for all 50 states, since actual state-to-state numbers were not available.)
Once we had the list of state numbers, we compared each one to Small Arms Survey’s list of countries and respective gun-ownership estimates, logging the nearest match.
The study revealed that:
California’s total of 33.08 million guns is closest to China’s 40 million
Texas’ total of 22.33 million guns is closest to Germany’s 25 million
New York’s total of 17.2 million guns is closest to Pakistan’s 18 million
