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 (PDF). The individual or organization requesting the vital records data must show that the data will be used for medical or scientific research, or that the release of the data is authorized by the Freedom of Information Act.
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.
Births are provided in aggregate tabulations only.
In Connecticut, birth records are confidential and made available to a few eligible parties as specified in C.G.S. §7-51. Any requests made for identifiable birth data must be approved by the Department of Public Health Human Investigations Committee.
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
Deaths and marriages are available in aggregate or as identifiable records with restrictions.
In Connecticut, C.G.S. §7-51a restricts the release of social security numbers for both death and marriage certificates. In addition, the state statute restricts the information collected in the ‘Administrative Purposes’ section of death certificates which includes Race and Hispanic Origin, Educational level, and Occupation and Business/Industry.
If you are interested in obtaining aggregate vital records data or unrestricted identifiable death or marriage data, please submit a written request to the Office of Vital Records at the Connecticut Department of Public Health at the address below. If you require restricted marriage and death data elements (other than the social security number), please visit the DPH Human Investigations Committee web page at http://www.ct.gov/dph/HIC for guidance.
