Butte County population history
Open historical explorerThe six July 1 estimates in the table belong to one consistent Vintage 2025 series. The Census Bureau revises earlier years when it releases a new vintage; a figure from an older publication may differ from the value below.
Vintage 2025, July 1, 2020–2025 Intercensal, 2010–2020
The highest observed population in this annual series was 210,204 in 2020. This is a peak within 2020–2025 coverage, not an all-time record.

Why is the April 2020 estimates base different from a census count?
The PEP estimates base here is 211,629 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.

The April 2020 census count (211,631) and the Vintage 2025 April 2020 base (211,629) differ by 2. The gap comes from boundary changes and the Census Bureau’s revised 2020 base, not population change, so measure growth within one series. Source and download
Growth and density
Between July 1, 2020 and July 1, 2025, Butte County lost 993 residents, a 0.47% decrease. The annualized change over these five elapsed years was -0.09%. 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 1,636.51 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 127.8 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire geography, 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
Components of population change
The published components cover July 1, 2024 through June 30, 2025. Natural change equals births minus deaths. Net migration is arrivals minus departures; it does not establish why people moved.
| Component | People |
|---|---|
| Births | 1,985 |
| Deaths | 2,217 |
| Natural change | -232 |
| Net domestic migration | +504 |
| Net international migration | +329 |
| Residual | +24 |
| Total population change | +625 |
Reconciliation: natural change + net domestic migration + net international migration + residual = +625. Births and deaths are already included in natural change and must not be added again. Source: co-est2025-alldata.csv; Vintage 2025.
