The RDI U.S. Census Database contains demographic information from the 2000 census for all census tracts in Harris, Fort Bend, Galveston, Montgomery, and Brazoria Counties. It also contains information from the 1980 and 1990 census for all zip code zones in Harris and surrounding counties. The information includes population distribution by age, sex, race, marital status, home ownership, income level, occupation, etc..

The RDI U.S. Census Statistics program has the ability to summarize demographic information over any region consisting of a set of one or more census tracts or zip code zones, so you can compare statistics for more than one region.

The RDI U.S. Census Statistics program also gives you some flexibility in choosing the type of information included in the report. If you choose one of the customized report formats, you will be given the option to include or exclude various classes of data; the appendix describes said classes of data. If you choose one of the standard formats, the report will include all the available data.
