Total population: All people, male and female, child and adult, living in a given geographic area.
Urban: The percent of the total population living in urban areas. The U.S. Census Bureau classifies as urban all territory, population, and housing units in areas that are densely settled. This generally consists of: - A cluster of one or more block groups or census blocks each of which has a population density of at least 1,000 people per square mile at the time.
- Surrounding block groups and census blocks each of which has a population density of at least 500 people per square mile at the time.
- Less densely settled blocks that form enclaves or indentations, or are used to connect discontiguous areas with qualifying densities.
Geographic entities, such as metropolitan areas, counties, and places, often contain both urban and rural territory, population, and housing units.
Rural (farm): The percent of the total population living in rural areas in farm residences. Rural consists of all territory, population, and housing units located outside of areas classified as urban. (See definition for "urban.") The farm population consists of people in households living in farm residences. An occupied 1-family house or mobile home is classified as a farm residence if: (1) the housing unit is located on a property of 1 acre or more, and (2) at least $1,000 worth of agricultural products were sold from the property in 1999. Group quarters and housing units that are in multiunit buildings or are vacant are not included as farm residences. Some people who are counted on a property classified as a farm (including, in some cases, farm workers) are excluded from the farm population. Such people include those who reside in multiunit buildings or group quarters.
Rural (not a farm): The percent of the total population living in rural areas in nonfarm residences. Rural consists of all territory, population, and housing units located outside of areas classified as urban. (See definition for "urban.") Nonfarm residences are all residences that are not classified as a farm. (See definition for "rural - farm.")
