Why the numbers differ
- The census count is a full count of residents as of April 1 of 2010 and 2020. It is the benchmark the yearly estimates start from.
- The population estimate is the bureau’s yearly figure for July 1, updated from the last census. It is the best figure for “how many people live in Alpharetta now.”
- The American Community Survey is a sample survey averaged over five years. Use it for age, income and housing, not for the headline population.
