Immigration Tripled in Top U.S. Counties Even as Many of Them Lost Population

Immigration to the top 10 most populous counties in the United States tripled between 2000 and 2023, even as many of them experienced population losses, according to recently released census data.

The new data, which was released by the U.S. Census Bureau, shows that the population of the top 10 most populous counties increased by 17.4 million people between 2000 and 2023, driven primarily by immigration. During this same period, the population of these counties decreased by 5.3 million people due to natural population decline.

The data shows that immigration was the primary factor driving population growth in the top 10 most populous counties. During the 23-year period, the number of immigrants to these counties tripled from 3.2 million to 9.2 million, accounting for more than half of the population growth in the top 10 counties.

The data also shows that while some of the top 10 counties experienced population losses, these losses were offset by immigration. For example, Los Angeles County lost nearly 2 million people due to natural population decline and domestic migration. However, the county gained 4 million people due to immigration, resulting in a net population gain of 2 million people.

The data shows that immigration is an important factor in population growth, especially in the top 10 most populous counties. It also highlights the importance of immigration in offsetting population losses in these counties. As the population of the United States continues to grow, immigration will likely remain an important factor in driving population growth in the top 10 counties.
