Community Health Data and Reports

Community health information & insights that matter to you.

The Health Improvement Team, part of the Community Health Improvement Department at Cambridge Health Alliance, works to shine light on strengths, concerns, and priorities related to community health. This page is for community members and leaders interested in exploring and using our analyses, reports, and recommended resources.

Community Data Profiles

These profiles contain statistics related to Community Demographics, Social Determinants of Health, and Health Outcomes in each community in CHA's primary service area. Click the name of each community to download its data profile. These profiles contain the most current data publicly available as of July 2020.

Tips for using the data profiles: 

  • Each profile contains three tables. Each table is organized by domain areas and categories, with multiple measures in each set.
  • The value of each measure is provided for the community and for the state of Massachusetts.
  • The value is typically expressed as a number and as a percentage or rate.
  • Each domain, category, or measure has a footnote, referencing the source of the statistic(s).
  • Data about populations can sometimes take years to collect and release, so it is important to note the dates listed in each source.


Community Health Assessments

Hospitals and public health agencies across the U.S. carry out comprehensive assessments every few years to guide plans for improving community health. The Health Improvement Team collaborates with community members and partner organizations and participates in coalitions to understand and report on health needs and strengths in our communities.

Our approach to assessment

Assessment begins with listening. Our approach to assessment revolves around asking questions that matter, lifting up community members’ priorities, centering equity, and collaborating to create solutions. We developed a framework to guide our approach, informed by experiences, lessons, and practices from our own communities and others around the country. Our framework is always evolving.
