Household ownership doesn't matter if the people who own them aren't likely to be involved in crimes - if a 50 year old farmer has a hunting rifle, their risk profile to society is really different than an angry 19 year old with a handgun.
While crime rates are per 100,000 people, population density makes a big difference because a low density, homogeneous population is going to have fewer interactions which turn negative. That's why people comparing crime stats usually compare cities or regions to avoid falsely reporting a correlation which is nothing more than a function of urban vs. rural density.
