The index utilizes data from the United States Census Bureau’s American Community Survey, mapped at the census tract level, providing detailed information of communities of approximately 4,000 people. Utilizing census data also enables the County to see trends over time, with the current iteration of the index comprised of the years 2010-2016.
The index is composed of seven indicators: health insurance coverage, education, supplemental security income, gross rent as a percentage of income, poverty, unemployment, and disability status.
