Massachusetts currently has the lowest uninsurance rate in the nation, and as part of the individual mandate to carry health insurance coverage, the state collects detailed information through its tax filing process about the health insurance status of over four million residents. This report analyzes 2011 and 2012 state tax filer data and provides new information about Massachusetts residents that are prone to remaining uninsured over consecutive years. The findings can help inform stakeholders who want to maintain the state’s low uninsurance rate and who strive to lower the number of individuals without health insurance coverage.
Prepared by Michael Chin of the University of Massachusetts Medical School and Audrey Gasteier of the Commonwealth Health Insurance Connector Authority, the analyses in this report represent the first time that tax filer data is being used to quantify the state’s uninsured population over a period of two consecutive calendar years. No other state has such detailed information on its residents’ insurance status.
