NOTE: Rural areas are located outside any urbanized area or urban cluster. Urbanized areas are densely settled areas containing at least 50,000 people. Urban clusters are densely settled areas with a population of 2,500 to 49,999. Fringe rural areas are 5 miles or less from an urbanized area or 2.5 miles or less from an urban cluster. Distant rural areas are more than 5 miles but less than or equal to 25 miles from an urbanized area, or more than 2.5 miles but less than or equal to 10 miles from an urban cluster. Remote rural areas are more than 25 miles from an urbanized area and more than 10 miles from an urban cluster. For more details on Census-defined areas, click here.
