Population forecasts for small areas (e.g., traffic analysis zones, school zone, neighborhoods, zip codes) often play an important role in public and private sector decision making.  They are essential in planning for future needs related to transportation, education, housing, emergency services, utilities, water resources, climate change, health care, local government planning, and many other goods and services.

County-level population projections don’t give enough detail for use in planning and decision making by local governments, utilities, transportation, schools, emergency services, or business/market studies. Geospatial models can meet this need.
