Annual Statistical Reports for Births, Deaths, Fetal Deaths, and Marriages (1992-current)
Each year, the Department of Public Health publishes a vital statistics report, also known as the Connecticut Registration Report, tabulating the number of births deaths, fetal deaths, and marriages that occurred in Connecticut or to residents of Connecticut. The information in this report comes from the statewide registries of births, marriages, deaths and fetal deaths maintained by the State Vital Records Office. The report provides counts of events by state, county, health district, and town as well as a variety of other birth and death statistics.
If you are a current member of a genealogical society that is incorporated or authorized to do business or conduct affairs in Connecticut, you are entitled to access all vital records except confidential files related to adoption, paternity, surrogacy agreements, and sex amendments related to gender re-assignment (see the current list of incorporated genealogical societies on the CT State Library Website). Also note that genealogists may not access the social security numbers on vital records consistent with federal law. If you would like to do genealogical research contact the town vital records office to schedule an appointment or the State Vital Records Office at (860) 509-7955. The vital records registry maintained by the State only contains records from 1897 to the present. For older records, you will need to contact the local vital records office or the Connecticut State Library.
Vital Records Data for Medical and Scientific Research Studies
The Department of Public Health may release vital records data to individuals and organizations, in accordance with Connecticut General Statute section 19a-25 and sections 19a-25-1 through 19a-25-4 of the Regulations of Connecticut State Agencies. The individual or organization requesting the vital records data must indicate that the data will be used for medical or scientific research, or that the requested data is not confidential or subject to any restrictions.
Requests may be made for aggregate or identifiable data. Aggregate data means data that is obtained by combining like data in a manner that excludes the identification of the individual described in the data. Identifiable data means any item, collection, or grouping of data that makes the individual or organization supplying it, or described in it, identifiable. Data elements that cannot be released per state statute will not be included in requests for identifiable data.
Birth data will only be provided in aggregate tabulations. In Connecticut, birth records are confidential and made available to a few eligible parties. Any requests made for identifiable birth data must be approved by the Department of Public Health Human Investigations Committee. Note that social security numbers contained in birth records cannot be released to any party, except for state and federal agencies authorized by federal law. If you are interested in obtaining identifiable birth data for research purposes please visit the Human Investigations Committee web site http://www.ct.gov/dph/HIC for guidance.
Death and Marriage Data
Death and marriage data are available in aggregate or as identifiable records. Note that social security numbers (SSN) contained in death and marriage records cannot be released to any party, except for state and federal agencies authorized by federal law.
Overall death counts for CT Residents and CT Occurrences:
Monthly death counts are available on our Vital Statistics webpage.
COVID-related requests for individual or aggregated death records:
- Connecticut is currently a paper-based death registry system.
- As a result, it takes 3 months for a death to be loaded into our electronic database.
- It takes an additional month for the ICD-10 Cause of Death codes to loaded into the electronic database.
- This is our normal process and is not a function of the COVID crisis.
- In response to COVID crisis, the Vital Records Office is working to speed up the processing of paper certificates.
- COVID-associated deaths will be processed before non-COVID deaths.
- There will still be a delay of 8-12+ weeks between the date of death and a completed COVID death record in an electronic format that is available for request.
- Non-COVID deaths for March 2020 to present will be processed after the COVID-associated deaths and may not occur until mid-summer.
- Requests for record-level death data will be limited to CT Occurrences. For deaths to CT Residents that occurred in other states, please contact that state directly.
- For any questions or comments related to COVID-19 deaths, please reach out to our DPH Communications Director, Av Harris (Av.Harris@ct.gov).
