Using Geospatial Models for Estimating and Projecting Population for Small Areas

  • Rich Doty, MA, GIS Coordinator & Research Demographer, BEBR

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.

Aging and Disability: Implications for the Housing Industry and Public Policy in the United States

The elderly population of the United States is large and growing rapidly. In 2000 there were 35 million persons age 65+, comprising 12% of the total population. By 2050 this population is projected to exceed 86 million, almost 21% of the total. Since disability rates increase with age, the aging of the population will bring substantial increases in the number of disabled persons and have a significant impact on the demand for housing. In this paper, we collect information on physical disabilities, particularly as they relate to mobility limitations.
