What does this measure? |
Population density, or population per square mile (land area), is a by-product of population growth, and indicates where growth occurs within the county. Monitoring changes in population densities provides an opportunity to assess land use in urban, suburban, and rural areas. Urban areas have population densities measuring at least 3,000 people per square mile, and are expected to have a concentrated mix of housing, retail, education, medical, recreation, and transportation options. Communities measuring below 1,000 people per square mile are rural areas, where residences and amenities are spread farther apart from each other, as the land is used primarily for agriculture, forestry, and horticulture. Population density impacts costs of service provision, as government and business investments are made based on the efficiency and expense of marketing, distributing, or serving populations over the expanse of a geographic service area.
