AUG. 12, 2021 — The U.S. Census Bureau today released additional 2020 Census results showing an increase in the population of U.S. metro areas compared to a decade ago. In addition, these once-a-decade results showed the nation’s diversity in how people identify their race and ethnicity.

acting Census Bureau Director Ron Jarmin

“We are excited to reach this milestone of delivering the first detailed statistics from the 2020 Census, We appreciate the public’s patience as Census Bureau staff worked diligently to process these data and ensure it meets our quality standards.”

The statistics, which come from the 2020 Census Redistricting Data (Public Law 94-171) Summary File, provide the first look at populations for small areas and include information on Hispanic origin, race, age 18 and over, housing occupancy and group quarters. They represent where people were living as of April 1, 2020, and are available for the nation, states and communities down to the block level.

The Census Bureau also released data visualizations, America Counts stories, and videos to help illustrate and explain these data. These resources are available on the 2020 Census results page. Advanced users can access these data on the FTP site.

Population Changes Across the Country Since the 2010 Census

This release reveals changes in the size and distribution of the population across the United States. The population of U.S. metro areas grew by 9% from 2010 to 2020, resulting in 86% of the population living in U.S. metro areas in 2020, compared to 85% in 2010.

Marc Perry, a senior demographer at the Census Bureau

“Many counties within metro areas saw growth, especially those in the south and west. However, as we’ve been seeing in our annual population estimates, our nation is growing slower than it used to. This decline is evident at the local level where around 52% of the counties in the United States saw their 2020 Census populations decrease from their 2010 Census populations.”

County and metro area highlights:

  • The largest county in the United States in 2020 remains Los Angeles County with over 10 million people.
  • The largest city (incorporated place) in the United States in 2020 remains New York with 8.8 million people.
  • 312 of the 384 U.S. metro areas gained population between 2010 and 2020.
  • The fastest-growing U.S. metro area between the 2010 Census and 2020 Census was The Villages, FL, which grew 39% from about 93,000 people to about 130,000 people.
  • 72 U.S. metro areas lost population from the 2010 Census to the 2020 Census. The U.S. metro areas with the largest percentage declines were Pine Bluff, AR, and Danville, IL, at -12.5 percent and -9.1 percent, respectively.
