Why is the April 2020 estimates base different from a census count?
The PEP estimates base here is 34,497 residents on April 1, 2020. It incorporates the Census Bureau’s corrections and geographic revisions and serves as the starting point for this annual series. It is not labeled an original 2020 census count. The chart starts at July 1, 2020, so its five-year change uses two July observations. Read about measurement types.
Growth and density
Between July 1, 2020 and July 1, 2025, Butte-Silver Bow (balance) gained 895 residents, a 2.59% increase. The annualized change over these five elapsed years was +0.51%. Annualized change is a summary of the interval; it does not imply that the population changed at that rate in every year.
The 2025 Gazetteer reports 715.76 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 49.6 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire place, rather than a typical neighborhood or built-up area.
Calculations use unrounded source values. Population counts are displayed as integers, percentages to two decimals and density to one decimal. Calculation methods · Growth calculator
Population characteristics and migration
This incorporated-place totals file does not provide city-level births, deaths, migration components or age distributions. Those statistics are not estimated from a county’s values here. County profiles provide supported change components, while age characteristics require a separately labeled PEP or ACS product. See characteristics coverage.
Geographic context
This is the whole incorporated-place record, not a metropolitan-area population. A place can span more than one county; the county links below come from published county/place-part relationships. County totals are context and are not substitutes for a city observation.
