Census 2000 estimates are computed for various characteristics of the population and housing of communities throughout the United States. These characteristics include demographic, social, and economic information about individuals and households; also, they include physical and financial characteristics of housing units. Of specific interest to this project, the Census 2000 contains information on age, race, sex, Hispanic origin (ARSH), family income, and family size. This information is used to establish Income to Poverty Ratios by ARSH. Census 2000 does not contain information on health insurance coverage.
The income and family information are from the Census 2000 "long form," an expanded set of questions asked of a sample of the total population (about 1 in 6). The race/Hispanic origin and sex information are from the Census 2000 "short form" asked of every person and at every housing unit in the United States.
