Background Information
Sample map Sample Map
The U.S. Census Bureau, with support from other Federal agencies, created the Small Area Income and Poverty Estimates (SAIPE) program to provide more current estimates of selected income and poverty statistics than the most recent decennial census. Model-based estimates are created for States, counties, and school districts. The main objective of SAIPE is to provide updated estimates of income and poverty statistics for the administration of Federal programs and the allocation of Federal funds to local jurisdictions. Estimates are modeled using a variety of data sources, including summarized information from individual Federal income tax returns, numbers of food stamp participants, and population information.

For the purposes of the SAIPE, poverty status is defined by family; either everyone in the family is in poverty or no one in the family is in poverty. The number of people in poverty is established using poverty income thresholds, which are dollar amounts used to determine poverty status and which vary depending on the number of people in the family, the number of related children under 18, and whether the primary householder is over age 65. An income threshold is determined given a particular family's set of characteristics; if that family's income is below that threshold, the family is in poverty.

The National Atlas offers two raw data files that include poverty and median income in the United States: Poverty and Median Income in the United States 1998-2000 and Poverty and Median Income in the United States 2001-2002. These two databases include poverty and median household income estimates, by county, for the fifty United States and the District of Columbia. The databases were produced by the National Atlas of the United States® from data obtained from the SAIPE. Included are statistics on the percentage of people in poverty, the percentage of people ages 0 to 17 in poverty, and the percentage of related children ages 5 to 17 in families in poverty. Also included are median household income estimates. Additional information on poverty thresholds is available from the U.S. Census Bureau How the Census Bureau Measures Poverty page.
