Accurate figures for civilian gun ownership are difficult to determine.[23] While the number of guns in civilian hands has been on the increase, the percentage of Americans and American households who claim to own guns has been in long-term decline, according to the General Social Survey. It found that gun ownership by households has declined steadily from about half, in the late 1970s and early 1980s, down to 32% in 2015. The percentage of individual owners declined from 31% in 1985 to 22% in 2014.[24] However, the Gallup organization has been performing similar polls for the same interval, and finds that household ownership of firearms was approximately the same in 2013 as it was in 1970 - 43%, and individual ownership numbers rose from 27% in 2000, to 29% in 2013.[23] Pew found that fewer Americans are dying as a result of gun violence: In 1993, there were seven homicides using firearms for every 100,000; by 2013, that figure had fallen to 3.6.[25]
