Sources & Uses of These Data .. goto top
Current state, regional and county data on demographic characteristics and trends are essential for wide-ranging analyses and decision-making. Annually updated model-based population estimates are developed by the Census Bureau for each county. These data are official estimates used in many Federal programs and other applications. ProximityOne uses these data to develop annual projections to 2060. We integrate the population and components of change data with other data to study trends and patterns.
