Correction made to the underlying data for Massachusetts chronic disease prevalence indicators.

Estimates were revised for five Massachsuetts chronic disease indicators. These data were produced by Massachusetts Department of Public Health (MDPH) using Electronic Health Records (EHR) from MDPHnet. Affected indicators:

  • Chronic Conditions – Asthma Prevalence (Electronic Health Records)*
  • Chronic Conditions – Diabetes Prevalence (Electronic Health Records)*
  • Chronic Conditions – Hypertension Prevalence (Electronic Health Records)*
  • Chronic Conditions – Obesity Prevalence (Electronic Health Records)*
  • Health Behaviors – Smoking Prevalence (Electronic Health Records)*

New data now available for the 2020 Census Participation indicator from the 2025 County Health Rankings.

The 2020 census self-response rate reports the percentage of all households that responded by internet, paper questionnaire, or telephone. Data were sourced from the Census Operational Quality Metrics and are used in the 2025 County Health Rankings. Note that estimates may differ slightly from original sources due to back-calculations using ACS housing unit data, and Connecticut planning regions report only rates due to boundary differences.
