California's Population Decline Hit These Counties Hardest

The latest census data shows how significant California's "mass exodus" has been.

The U.S. Census Bureau's latest report stated that more than two-thirds of the nation's counties experienced a natural population decrease in 2021 and that the COVID-19 pandemic's impact on births and deaths was the primary contributor.

For San Diego, whose population had steadily grown for decades, the decline actually started before the pandemic. Lack of housing and the high cost of living have continued to make America's Finest City unlivable for many.

Over 5,000 San Diego residents died as a result of the pandemic, and according to the census bureaus data, more than 7,000 moved away.

  • July 1, 2019 3,297,252 
  • July 1, 2021 3,286,069

Across the U.S. these 10 counties experienced that greatest population loss (April 1 - July 1, 2021):
