These California counties saw the biggest population decline during the pandemic

New U.S. Census data released Thursday shows several California counties ranking high on the list of regions that saw the biggest decline in population during the height of the COVID-19 pandemic.

The Census looked at the US counties that saw significant population declines between April 1, 2020 and July 1, 2021, simultaneously with the start of the pandemic.

Here are the California counties that made the national list's top 10.

  • Los Angeles County— Decline of 184,465 residents
  • San Francisco County— Decline of 58,764 residents
  • Santa Clara County— Decline of 50,751 residents
  • Alameda County — Decline of 33,797 residents

Los Angeles lost almost 176,000 residents, the second-biggest drop among US metro areas. Like New York, births outnumbered deaths, and there was an increase in international residents. But it wasn’t even close enough to overcome the loss of tens of thousands of residents who moved away. Its population dropped to 12.9 million residents.
