About the Data
This report uses data from the American Community Survey (ACS), conducted by the U.S. Census Bureau. This report uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau.
Unlike the Census — which is an exact count of people and households every 10 years — ACS statistics are estimated based on a representative survey sample. The ACS releases two kinds of data: one-year and five-year estimates. The one-year estimates provide more current data, but are not available for small locations like census tracts, and are unreliable for small demographic slices. The five-year estimates provide greater detail and accuracy by widening the period of the survey.
Cost-burdened Housing data was calculated by LiveStories based on data from ACS Table B25106. The calculation sums all housing units where housing costs comprise 30% or more of the occupants' household income, and also sums households with zero or negative income. This sum is then divided by the total number of occupied housing units to yield a percentage. For owner-occupied housing units, the costs are monthly owner costs; for renter-occupied units, the costs are gross rent.
Life Expectancy data is from the United States Small-Area Life Expectancy Estimates Project.
