What stands out

Missouri had an estimated population of 6,245,466 on July 1, 2024, according to the Census Bureau's Population Estimates Program. Since July 2020 that is +1.5 % (90,722 people); since 2010 it is +4.2 %. Migration is the larger driver since 2020: net migration +101,941 against a natural change (births minus deaths) of -11,763. Among the 51 states in the United States, it ranks 19 by population. Values for 2010–2019 and 2020–2024 come from two estimate vintages benchmarked to different censuses; the 2019→2020 step is partly a rebasing.

Every figure shown here about Population of Missouri can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.
