United States Census Bureau:The Census Bureau definitions (new to the 2000 census), which are based on population density,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych] defines rural areas as all territory outside of Census Bureau-defined urbanized areas and urban clusters.:*An urbanized area consists of a central city and surrounding areas whose population ("urban nucleus") is greater than 50,000. They may or may not contain individual cities with 50,000 or more; rather, they must have a core with a population density generally exceeding 1,000 persons per square mile; and may contain adjoining territory with at least 500 persons per square mile (other towns outside of an urbanized area whose population exceeds 2,500).:*Thus, rural areas comprise open country and settlements with fewer than 2,500 residents; areas designated as rural can have population densities as high as 999 per square mile or as low as 1 person per square mile.[2];USDA:* The USDA'sOffice of Rural Development may define rural by various population thresholds. The 2002 farm bill (P.L. 107-171, Sec. 6020) defined rural and rural area as any area other than (1) a city or town that has a population of greater than 50,000 inhabitants, and (2) the urbanized areas contiguous and adjacent to such a city or town.:* The rural-urban continuum codes,[link widoczny dla zalogowanych] urban influence codes, and rural county typology codes developed by USDA’s Economic Research Service (ERS) allow researchers to break out the standard metropolitan and nonmetropolitan areas into smaller residential groups.[2] For example, a metropolitan county is one that contains an urbanized area, or one that has a twenty-five percent commuter rate to an urbanized area regardless of population.;OMB: Under the Core Based Statistical Areas used by the OMB,::* a metropolitan county, or Metropolitan Statistical Area, consists of (1) central counties with one or more urbanized areas (as defined by the Census Bureau) and (2) outlying counties that are economically tied to the core counties as measured by worker commuting data (i.e. if 25% of workers living there commute to the core counties,[link widoczny dla zalogowanych] or if 25% of the employment in the county consists of workers coming from the central counties).::* Non-metro counties are outside the boundaries of metro areas and are further subdivided into Micropolitan Statistical Areas centered on urban clusters of 10,000-50,000 residents, and all remaining non-core counties.[2][3]
