In year-to-year estimated population changes from 2020 to 2021, per the U.S. Census, Los Angeles County saw its largest decrease over at least the last 51 years. The county's population fell by 159,621 or 1.6 percent. It was also the single largest population decrease for any U.S. county. It should be noted, however, that Los Angeles County is, by far, the most populous county in the United States. Seven of the nation's 30 most populous counties saw even larger percentage decreases than did Los Angeles County (four of five New York City counties, Santa Clara and Alameda Counties in California, and Cook County in Illinois). Furthermore, Los Angeles County suffered the loss of more than 24,400 lives to COVID-19 by the Census 2021 population estimate date of July 1, 2021.
