Census population estimates, July 1 each year. The scale does not start at zero.
County Business Patterns, private employers.
ACS 5-year estimates carry margins of error; *_moe fields are 90% MOEs. Small counties (Petroleum, Garfield, Treasure…) have wide MOEs. Median home value is top-coded at $2,000,001. Sources: American Community Survey 5-year estimates, 2020–2024; Population Estimates Program, Vintage 2025 county totals; Building Permits Survey, county annual and monthly files; Fair Market Rents, FY2026 (effective Oct 1 2025) — HUD eGIS feature service; County Business Patterns 2023 (fallback for BLS QCEW).
Known gaps
- Building permits: no city or county here publishes permits online. New construction appears only through state permits (DEQ, MDT) and new address points.
- Recorded documents: the recorder’s index is not online; documents are searched in person at the courthouse.
- Hearing agendas: commission and planning board agendas are not read for this county yet.
- Zoning: no zoning districts on file. Much of the county may be unzoned; check with the county planner.
- Sale prices: Montana does not disclose sale prices, so none appear on Data 4 MT.
