Centralia, Iowa: commercial real estate data.

Centralia is a Census city of 117 people across 0.62 square miles of land, in Dubuque County. Median household income is $77,500, 80.0 percent of occupied homes are owned.

Underlined figures are computed by MMCG Analytics, not published by the agency.

This is a small place, and the figures below carry wide margins.

The American Community Survey reaches Centralia through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 117 with a margin of error of plus or minus 63, which is 53.8 percent of the estimate itself. Every figure whose margin reaches 20 percent is printed with that margin beside it, so you can see the width of each one rather than having to assume it.

Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.

No, it is listed but not participating. Centralia appears in the FEMA Community Status Book as Centralia, city of, community 190500, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.

They appear in one clearly marked section as context and are never presented as measurements of Centralia.

Is zoning published for Centralia?
