This brief and set of detailed tables, prepared by Sharon Long and Thomas Dimmock from the Urban Institute, provide estimates of the number and rate of uninsurance in Massachusetts by various geographic units ranging from congressional districts to counties to neighborhoods. The resource is based on the 2009 to 2013 five-year file of the American Community Survey (ACS), which included a sample of 140,001 people in Massachusetts.
The brief summarizes high level findings from the data and definitions for the geographic units of analysis. The appendices provide data on the estimates of the number and rate of uninsurance by the following categories: all persons, males, females, children (ages 0-17), non-elderly adults (ages 18-64), and elderly (ages 65+). Each appendix provides these results for 10 different geographic units ranging from congressional district to county to census tract.
