The Economic Hardship Index (EHI) provides a comprehensive measure of economic conditions using six socioeconomic indicators from the 2014 5-Year American Community Survey (ACS) data:
3. Lack of Education
4. Lack of Adequate Income
5. Crowded Housing
6. Below Poverty Level
Within each county, census-tract level estimates of these six indicators were standardized to give them equal weight then combined into a composite index. The index score represents the average of the six standardized indicators and ranges from 0 to 100, with a higher score indicating worse economic conditions.
