1990-2018

  • The April 1, 2018 population estimate places Washington’s population at 7,427,570. This represents an increase of 117,270, or 1.60 percent, since last year.
  • Washington's annual rate of population growth had been below 1.0 percent from 2009 to 2013 due to the sluggish economy. Economic activity has a strong influence on net migration.
  • Washington's population has experienced wide swings in growth. One of the low-points of the post-war era came in 1972, in the aftermath of the Boeing-bust. Washington experienced a decline in population as ranks of unemployed aerospace workers and others sought gainful employment outside Washington state.
  • A rebounding aircraft sector, and solid economic growth overall, resulted in record growth in 1980 when population expanded by 3.85 percent, a pace unmatched since.
