Center for Health Data and Analysis

The Center for Health Data and Analysis (CHDA) collects and analyzes health data on the Rhode Island population and uses the data to identify health problems among the state's population and subgroups. CHDA also supports health programs in their health planning and evaluation efforts.  State-wide data systems provide a variety of health statistics, including health status, health care utilization, health insurance coverage, health risk behaviors, hospitalizations, natality (birth certificate), and mortality (death certificate).

Selected surveys from data sets include the following:
