Methodology and Data Sources
Data sources include:
- Census tabulations from 1980, 1990 and most recently, the release of the 2000 Census
- The Census Bureau’s American Community Survey (ACS) results. The ACS is an annual survey which over the course of several years will result in a national rolling estimates database which is eventually intended to replace the decennial SF3 sample database.
- USPS and commercial source ZIP+4 level delivery statistics.
- Census Bureau estimates and projections of population characteristics at various levels of geographic detail, including the latest estimates of population at the city level.
- Bureau of Labor Statistics estimates and projections of employment by industry and occupation at the county level.
- Medicare eligible population counts at the ZIP code level, including population by sex and 5-year age cohorts, provided by the Health Care Financing Administration of Social Security. These counts provide a very accurate local count of the population aged 65 and higher.
- Internal Revenue Service statistics on tax filers and year-to-year migration.
- The Census Bureau’s Current Population Survey, which provides detailed demographic breakdowns and enables a thorough longitudinal analysis of demographic trends.
- Experian’s INSOURCE database, a household level credit and demographic database which covers the vast majority of households.
