This link contains demographic information collected by the Census Bureau in 2000 for the census block, census block group, census tract, and county levels in both shapefile and GDB formats. Due to their age, these datasets have been removed from our databases and are now stored as static files in Google Drive.

The Census Bureau creates different sized geographic areas to organize demographic information (population, household counts, ethnicity, etc), the smallest unit of area being a "census block" and the biggest being counties.

The 2000 Census was the last to use the "long-form" questionnaire to sample a portion of the population for more detailed information. Starting in 2010, the Census Bureau replaced the long-form with the American Community Survey (ACS), which is an ongoing sample that provides data every year instead of every 10 years.

Summary File 1 and 2 focus on the information collected on the census short form - namely on age, sex, race, Hispanic/Latino origin, households, families, housing units, and owner/renter status.

Summary File 3 and 4 focus on 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. Topics include income, education, occupation, ancestry, disability, foreign birth, commuting, household financial arrangements, year housing structure built and many other population and housing subjects.
