About Connecticut Public Health Tracking DATA


The Connecticut Environmental Public Health Tracking (CT EPHT) Program is funded by the CDC to develop and implement a web based data portal. The data explorer is used to present nationally consistent data and measures (NCDMs), as well as some state specific measures and data. Included in the NCDMs, are measures for air quality, reproductive outcomes, birth defects, cancer, carbon monoxide hospitalizations, childhood lead poisoning, public drinking water quality, asthma hospitalizations, and hospitalizations for acute myocardial infarction.
On the CT Public Health Data Explorer, you can explore information and view tables and charts about health and the environment in the state of Connecticut.

Data Suppression Rules

The data presented on the Connecticut Public Health Data Explorer are publically available data.
Some data has been suppressed in order to prevent the disclosure of personal identifying health information.
Non-zero counts that are less than 6 are suppressed for areas with a total population less than 100,000 persons.
In addition, rates are checked for their stability, so that trends over time and between geographic areas or persons can be evaluated with reasonable confidence. Any rate with a relative standard error (RSE) greater than or equal to 30% is flagged as unstable.
More detailed data may be available by contacting the CT EPHT Program directly.
