Looking at
GSS results, they seem to be highly variable from year to year with regards to gun ownership.
For example, in 1987, 48.6% of households reported owning guns. In 1988, the number was 43.4%. In 1989, the number was 48.9%. Do we really believe that gun ownership took a big jump down from 1987 to 1988 then bounced back to essentially the same level it was in 1987 in 1989? Did gun ownership really change or is there some flaw in the way it is measured?
