Net interstate balance

Washington's population in the year to July 2025

On July 1, 2025, Washington had an estimated 8,001,020 residents, 73,062 more than a year earlier (+0.92%). Ranked by that rate of change, it is 7th of the 50 states and DC.

Components of change in the year to July 2025
  • Natural change (births minus deaths)+17,230
  • Net international migration+46,202
  • Net domestic migration (other states)+9,238

All three parts of the change added people: net international migration (46,202), natural change (17,230) and net domestic migration (9,238), largest first. Births outnumbered deaths, 83,368 to 66,138. The remaining 392 is the Census Bureau's residual, change the three parts do not explain.

Net domestic migration came to 1.2 per 1,000 residents, 24th among the 50 states and DC. Counting international arrivals too, net migration was 7.0 per 1,000.

Against the April 2020 estimates base of 7,707,519, the 2025 estimate is up 3.8%.

Both Census sources point the same way: the state-to-state survey counted more arrivals than departures, outside its margin of error, and the 2025 estimate puts net domestic migration at +9,238.

Reading the latest table

Washington's partner directions pull against one another

California sends an estimated 43,938 people into Washington and receives 26,956 from it. The inward difference, 16,982 ±7,360, clears the site's 90% threshold. Oregon also leans toward Washington by 11,953 ±5,367.

The reverse pattern appears with Idaho and Arizona: Washington's outward differences are 9,910 ±4,059 and 8,963 ±4,169, respectively. These reported pairs should not be added as if they covered every state. Washington's total inward difference is 17,707 ±15,947, just beyond the comparison margin in this one-year table; it is not a forecast.

Differences use the site's published 90% comparison method. These ACS figures describe residence one year earlier, not shipments or moving prices. Read the method.
