Housing in Flora Township
Real Census numbers for Flora Township: about 2,988 residents and 1,255 housing units spread over 36.5 square miles. That's roughly 82 people per square mile, a mid-density township rather than open farmland. At this population size the Census Bureau doesn't break out housing age or tenure separately, so what shows up on the Boone County towns elsewhere on this site is the nearest real comparison, not a Flora Township-specific number.
