Maps and Geographical Analysis

CHIA has recently produced several interactive maps of Massachusetts health care data. These maps allow users to better understand variations in health care spending and utilization by displaying recent data on a town-by-town or regional basis.

The Massachusetts Patient Origins map shows areas from which Massachusetts hospitals and hospital systems draw their patients by illustrating the distribution of hospital inpatient discharges in 2016 by patient zip code.

The Massachusetts Commercial Total Medical Expenses by Town and Region map illustrates geographic variation in spending by commercial health insurers on behalf of their commercial full-claim members in 2014.
