In my case, it’s about the same. I can’t speak for others.
Again, it’s about the same, except that I never sent my children to school in an urban area.
That may be true in some small towns in rural areas, but it’s just not true in suburbs. For example, the vast majority of people in my town of ten to twenty thousand are people whom I do not know.
In any event, my point still stands even if you just look at family members. For example, according to the chart at the bottom of this page, the rate of homicides between intimates (spouses, ex-spouses, boyfriends, girlfriends, etc.) was a lot higher in rural areas than in suburbs and a lot higher in suburbs than in urban areas.
