Big Rock, Tennessee Demographics & Population 2026

A note before these figures: with a population of 163, Big Rock's ACS estimates come from a small number of survey responses and carry wide margins of error. Individual percentages below — particularly rates that round to 0% or 100% — are approximations, not precise measurements. See data.census.gov for the published margins of error.
