Wyoming population history
Open historical explorerThese six July 1 estimates 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.
Annual estimates · 2020–2025 · Vertical scale shown on chart.
The highest observed population in this annual series was 588,753 in 2025. 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 576,872 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.
Decennial census counts, 1910–2020
These are separate census observations from the Census Bureau’s historical population-change table. Historical geographic definitions apply; they are not standardized to the 2025 boundary. Alaska and Hawaii were not states throughout this period. Census dates changed historically: April 15, 1910; January 1, 1920; April 1, 1930 and 1940; and April 1 from 1950 onward. The national historical source must be read with its coverage notes.

Growth and density
Between July 1, 2020 and July 1, 2025, Wyoming gained 11,084 residents, a 1.92% increase. The annualized change over these five elapsed years was +0.38%. 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 97,088.55 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 6.1 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 | 6,070 |
| Deaths | 5,775 |
| Natural change | +295 |
| Net domestic migration | +1,474 |
| Net international migration | +258 |
| Residual | +4 |
| Total population change | +2,031 |
Reconciliation: natural change + net domestic migration + net international migration + residual = +2,031. Births and deaths are already included in natural change and must not be added again. Source: NST-EST2025-ALLDATA.csv; Vintage 2025.

Geographic context
County totals below describe separate county units. Incorporated cities are not an exhaustive division of a state, so their populations must not be summed as a state control total.
