This is a list of countries by estimated number of privately owned guns per 100 people. The Small Arms Survey 2017[1] provides estimates of the total number of civilian-owned guns in a country. It then calculates the number per 100 people. This number for a country does not indicate the percentage of the population that owns guns. This is because individuals can own more than one gun.
