 About Counties

In the United States, there are 3,069 counties, which vary greatly in size and population. They range in area from 26 square miles (Arlington County, Va.) to 87,860 square miles (North Slope Borough, Alaska). The population of counties varies from Loving County, Texas, with 140 residents to Los Angeles County, California, which is home to 9.2 million people.

Forty-eight of the 50 states have operational county governments. Connecticut and Rhode Island are divided into geographic regions called counties, but they do not have functioning governments. Alaska calls its counties boroughs and Louisiana calls them parishes.

NACo researches, publishes and disseminates a variety of information for and about counties, as part of its mission to increase public understanding of counties. This section provides access to this information.
