Description:

This file contains the initial 2010 census population and housing data at the census block level for blocks defined as being in the City of Houston by the Census Bureau. The population and housing totals in this file represent summarizations of the 288 data items in the original census files. Specifically, populations are aggregated for Hispanic ethnicity and Non-Hispanic populations by 7 racial categories. These same aggregations are available for voting age populations (18 years and over). Housing data is limited to total, vacant and occupied units.
