Housing in Spring Township
Spring Township has an estimated population of 1,009 and 375 housing units across 36 square miles. That's about 28 people per square mile, thin enough that most of the land here is farmland, not subdivisions. The Census Bureau doesn't separately publish a detailed housing-age or tenure breakdown at this population size, so Boone County's own numbers, on the other Boone County pages on this site, are the closest real context for Spring Township specifically, not a figure unique to it.
