Frequently Asked Questions
What is the difference between Summary Tape File 1 and Summary Tape File 3?
Summary Tape File 1 (STF 1) contains 100-percent population and housing figures common to the Census short form and long form. It includes such subjects as age, race, sex,
Hispanic origin, household relationship, housing units, housing tenure, vacancy characteristics, and home value or monthly rent. Summary Tape File 3 (STF3) contains detailed statistics about a sample of the population. STF 3 topics include ancestry, citizenship, disability status, education, income, labor force and work experience, language spoken at home, migration, residence, veteran status, and housing characteristics.
How do I find income and poverty statistics?
Income and poverty statistics are included in the Economic Characteristics report from Summary Tape File 3. These data are available by Census tract, zip code, city, county, and region, as well as in a radius summary from a given street address. Data for radius summaries are summarized by Census block group or tract.
How can I find out which Census tracts are in a given city?
Create a map of the city with Census tracts overlaid. Note that only Census blocks nest exactly to city boundaries; there will always be some overlap with tracts and block groups.
Why isn't Hispanic included as a race category?
Race and ethnicity are considered to be two separate and distinct concepts. Therefore, two separate questions -- one for race and one for ethnicity or Hispanic origin are used whenever feasible to provide flexibility and ensure data quality. As such, Hispanic persons can be of any race.
What is the difference between a Census tract, Census block group and Census block?
 Census tracts (yellow lines) are small, relatively permanent statistical subdivisions of a county. The primary purpose of Census tracts is to provide a stable set of geographic units, making it possible to compare statistics for the same geographic area from one Census to another. Census tracts generally have between 1,500 and 8,000 people, with an optimum size of 4,000 people.
Block groups (blue lines) are clusters of Census blocks having the same first digit of their four-digit identifying numbers within a Census tract. Block groups generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. Block groups are the smallest Census geography for most Summary Tape File 3 data.
Census blocks (red lines) are areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and by invisible boundaries, such as city, town, township, and county limits, property lines, and short, imaginary extensions of streets and roads. Generally, Census blocks are small in area; for example, a block bounded by city streets. However, Census blocks in remote areas may be large and irregular and contain many square miles. Census blocks are the smallest Census geography for Summary Tape File 1 data.
Where can I get Census information for cities and counties in other parts of Texas?
