Population over time
2 figuresFlat Rock fell from 331 to 323 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Carmel to Chicago) was taken by Asa Jones, and he was shortly afterwards followed Richard Highsmith, another pioneer, helped in constructing the fort at Russellville, and slept in it with a few others as soon as it was finished.
