Notes:
The Census Bureau used two different forms to collect Census 2000 data. A short form (100% data) with seven basic questions went to all households and a long form with these same questions and additional questions went to a sample of households. Summary File 1 presents counts and basic cross-tabulations of information collected from all people and housing units.
The questions asked on the short form included: name; sex; age; household relationship; Hispanic origin; race, and whether the home was owned or rented. About 83 percent of households received the short form. The information that is tabulated from the questions asked of every person and housing unit is called the100-percent or short-form data.
The long-form questionnaire included the same seven population and housing questions plus additional inquiries. On average,1 in every 6 households received the long form. The information that is tabulated from the questions asked of this sample of persons and housing units is called sample or long-form data.
