This policy brief by Sharon Long of The Urban Institute measures geographic and racial disparities in access to health care in Massachusetts. The data in the brief comes from the third annual Massachusetts Health Reform Survey. This revised version of the policy brief, which was originally published 5/28/2009, reflects changes made after an error in constructing survey weights was discovered and corrected. These changes do not impact the basic findings and conclusions in the original policy brief with respect to geographic differences; however, it does lead to more evidence of racial/ethnic differences in the affordability of health care in Massachusetts.
