Some interesting gun ownership facts in
this NYTimes chart from exit polls 4 years ago.
Obviously there is a huge difference between Democrats and Republicans. But when you look at Republicans, the only places where you see significant different ownership rates are by race, and also by population density. Not many Republicans in the city own guns, and not many Asian Republicans own guns, but when you look at all the other breakdowns, Republicans have consistently high ownership rates.
Then you look at the Democrats, and they are all over the map in every category. A rural Democrat is gonna have a gun. An atheist Democrat won't have a gun. A high school educated Democrat might have a gun, but if they went to college, they probably won't. You can make these sweeping statements for each category. It's really interesting.
