About the Data
This report uses data from the American Community Survey (ACS), conducted by the U.S. 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.
