The U.S. Census Grids provide raster data sets that include not only population and housing counts, but a wide variety of socioeconomic characteristics. These gridded data sets transform irregularly shaped census block and block group boundaries into a regular surface – a raster grid – for faster and easier analysis. Data sets are available for 1990 and 2000.
Type of Data Available
- Individuals - age distribution, race, ethnicity, income, poverty, educational level, and immigrant status
- Households - household size, one-person households, female-headed households with children under 18, and linguistically isolated households.
