Firearms Prevalence By State Estimated From HICRC And From FS/S

In this graph, you can see gun ownership estimates calculated using the FS/S method correlate positively with gun ownership estimates from surveys done by the Harvard Injury Control Research Center (HICRC) in 1996 and 1999.

This graph does not include data from Hawaii or the District of Columbia, which were not included in the HICRC study.
