Smallest counties in every state

  • Smallest county in every state

    The structure of the United States is unique. It’s a country made up of 50 states, each of which consists of various counties, cities, states, and towns. Depending on where it's located, an area might have three or four layers of local government. It’s almost like a geographical Russian nesting doll.

    This set-up largely makes sense — except in a few cases. Some states are so sparsely settled that geographically large counties have tiny populations while others might only cover a few square miles but hold hundreds of thousands of people. To see how much this varies from state to state, Stacker examined population data gathered by U.S. Census Bureau from 2010 to 2017 to compile this list of the smallest counties in every state. The Census Bureau’s population estimates are based on the population base, plus migration numbers, plus the births-minus-deaths total. The growth rate was determined by dividing the difference between present and past populations by the past population, using population data from the Census Report. Read on to find out which county in your state has the smallest population and which state has a county with a population of just 88 residents.

  • Alabama: Greene County


    2017 population estimate: 8,330

    2010 census population: 9,045

    Growth rate (since 2010): -7.90%


    Eutaw, the largest city in this county in western Alabama, has just 2,122 people. The average household income was $50,498 in 2016.  


  • Alaska: Yakutat City and Borough


    2017 population estimate: 605

    2010 census population: 662

    Growth rate (since 2010): -8.61%


    The small fishing village of Yakutat, which is also the borough seat, has been inhabited by the Tlingit people for hundreds of years. In their native tongue, Yakutat means "the place where canoes rest.”


  • Arizona: Greenlee County


    2017 population estimate: 9,455

    2010 census population: 8,437

    Growth rate (since 2010): 12.07%


    First settled in 1874 by miners who discovered that the area hosts large copper deposits, Greenlee County remains economically dependent on the mining industry. Clifton, a city near the county’s geographical center, won the honor of being its county seat.  


  • Arkansas: Calhoun County


    2017 population estimate: 4,833

    2010 census population: 5,089

    Growth rate (since 2010): -5.03%


    This county was originally named Benton County after Missouri senator Thomas Hart Benton, who served in Alabama during the War of 1813-14. However, the state senate voted to change the name to Calhoun County in 1858 to honor Vice President John C. Calhoun.


  • California: Alpine County


    2017 population estimate: 1,120

    2010 census population: 1,175

    Growth rate (since 2010): -4.68%


    This tiny county on the border between California and Nevada just south of Lake Tahoe has a rich history. The Washoe people were the first residents. Famous explorers, including John Fremont and Kit Carson, first journeyed across the Sierra Nevada mountain range through the region. It was eventually settled by prospectors looking for gold.


  • Colorado: San Juan County


    2017 population estimate: 715

    2010 census population: 699

    Growth rate (since 2010): 2.29%


    There’s only one city in San Juan County: Silverton, which boasts only 637 residents. The county has an average elevation of 11,240 feet, which is the highest in the country.


  • Connecticut: Windham County


    2017 population estimate: 42,869

    2010 census population: 44,513

    Growth rate (since 2010): -3.69%


    Though Windham County is much larger than many of the counties on this list, it’s still Connecticut’s smallest. It’s also not a particularly diverse county: more than 92% of the residents are white.


  • Delaware: Kent County


    2017 population estimate: 763

    2010 census population: 808

    Growth rate (since 2010): -5.57%
