If you look at the stats by Pew, Harvard and other research organisations, the number of individuals owning guns is declining. Some estimates reckon it's about 22% now. The number of households with access to a gun is declining, down from 40% to 36%. Those two stats tie in.
The number of guns is increasing, enormously. It's not a proportionate spread - the north east states have low gun ownership. The highest are rural states, like Montana and Wyoming, and the southern states. Some people in some states are buying more and more guns.
Most likely to be involved in gun crime are black people - either as perpetrators or victims. More than half of all shootings involve back people, although the black population is 12% of the total. Hispanic groups are next most likely to be involved, with 17% of the population and 25% of the gun incidents.
It's complex.
