How to read these numbers
The census is a full count every 10 years, taken as of April 1. Population estimates are the Census Bureau’s yearly figures for July 1, built from births, deaths and migration; they are revised each year. The American Community Survey is a sample survey; the five-year figures pool responses from 2020 to 2024 and carry margins of error, so small differences between places may not be meaningful.
