Massachusetts Health Insurance Survey

2019 Massachusetts
Health Insurance Survey

The Massachusetts Health Insurance Survey (MHIS) provides information on health insurance coverage, health care access and use, and health care affordability for Massachusetts residents as part of CHIA’s Continuing Study on Insurance Coverage, Underinsurance and Uninsurance.   

The MHIS is a tool used by CHIA, legislators, policymakers, employers, insurers and other stakeholders to track and monitor the experiences of Massachusetts residents in obtaining timely and affordable health care. While national data sources can help to monitor some aspects of health insurance coverage and health care access, this survey provides the ability to track issues that are specific to Massachusetts. The MHIS additionally enables CHIA to track key populations that are of particular interest to the Commonwealth. The 2019 MHIS was fielded between April and July 2019.

This research brief, published by CHIA in April 2019, documents the scope of health care affordability issues among Massachusetts residents with health insurance coverage all year (referred to as insured residents) and the rates of affordability issues for population subgroups.




This research brief compares the methodologies used to calculate the Commonwealth's health uninsurance rate using survey data. The Massachusetts uninsurance rates are quite similar despite differences in survey methodologies used across surveys.
