This is a list of the 100 most populous counties in the United States based on the national decennial US census conducted on April 1, 2020 and vintage Census population estimates for July 1, 2022.[1]
Counties by population, with darker purples indicating a higher population, from 2020 census data
A map of the counties and county equivalents of the United States. The 100 most populous counties are highlighted, with counties having more than one million residents in orange and counties having fewer than one million residents in green, based on the results of the April 1, 2020 United States census.
Many of the most populous counties listed are in Southern California, Illinois, Texas and New York and roughly correspond to the most populous cities in the United States. Counties in the Western United States are typically larger, so they often have higher raw populations even with comparable population densities.
