Frequently Asked Questions

• What is the difference between 100-percent (SF1) and sample (SF3) data?
  • 100-percent (SF1) data corresponds to a limited number of questions asked of every person and housing unit in the United States. These included sex, age, household relationship, race and Hispanic origin, and tenure.
    

    
    Sample characteristics (SF3) data provides additional information on a sample of persons and housing units. These included social and economic characteristics of the population, and physical and financial characteristics of housing units. Approximately one in six households nationwide received the long form.

• What is a Census Tract?
  • Census tracts are small, relatively permanent statistical subdivisions of a county. The U.S. Census Bureau uses the census tract geographic boundary system to collect, tabulate, and present decennial census and other data. Census tracts generally have between 1,500 and 8,000 residents. There are a total of 715 census tracts in the region.
• What is a Census Designated Place (CDP)?
  • CDPs are unincorporated communities that are identifiable by name, with concentrations of population, housing and commercial structures. They are delineated for each decennial census for reporting purposes, and are the statistical counterparts of incorporated municipalities. CDP boundaries may change from one decennial census to the next.
