Thematic data for the state, counties, places, tracts, and legislative districts
These data files are extracts of the most widely used items from Census 2000 Summary File 3 (SF3) data – social, economic and housing characteristics compiled from a sample of approximately 19 million housing units (about 1 in 6 households) that received the Census 2000 long-form questionnaire.
Single-topic data files are available for the following topics. Each file contains data at the state, county, and place level.
1. Data for states, counties, and cities
- Population and housing
- Living arrangements and parental employment
- Income categories by race
- Median income, per capita income
- Poverty
- Employment status
- Industry employment
- Occupational employment
- Educational attainment
2. Data for census tracts by county
3. Data for legislative districts
The sample data from Census 2000 Summary File 3 (SF3) are not available for legislative district boundaries from the Census Bureau. To create estimates of household income, education, labor force, and other characteristics by legislative district, OFM needed to allocate sample data to each district. This allocation is made based on the proportion of population (or housing) each census tract contributes to each legislative district area. If, for example, a census tract had 30% of its population living in legislative district A-and 70% of its population in district B-then 30% of the sample tabulations would be allocated to district A and 70% to district B. Those tracts and tract parts in each legislative district are then summed to make the legislative district total.
