Death Data Files

Unless there is a specific need for personal identifiers, non-confidential data files should be used.  Some fields on the death files are only available for specific uses as prescribed by law.  Confidential Death Files include personal identifiers such as Mother’s Maiden Name (MMN) and/or Social Security Number (SSN).  Users may need to obtain approvals from the California Department of Public Health Vital Statistics Advisory Committee (VSAC) and the California Health and Human Services Agency's Committee for the Protection of Human Subjects (CPHS) in order to use confidential data files for research purposes.  Once the files are obtained, users must follow strict guidelines to protect the confidentiality of the data.   

Description of Files

Death Data files are compiled from the information reported on the death certificates, including detailed demographic information related to the decedent.  Below are brief descriptions of available death data files. 

  • Death Statistical Master Files

  • The Death Statistical Master Files are the largest and most comprehensive of the death data files.  These files are available with or without the personal identifiers.  CPHS and the VSPAC approvals are required to obtain the Death Statistical Master Files with social security numbers or mother's maiden names.
  • Death Public Use Files 

  • The Death Public Use Files are subsets of the Death Statistical Master Files.  The file structure and the variable coding methodology are designed to facilitate trend analysis and to simplify computer programming.  These files contain the most commonly used variables and do not contain any personal identifiers.

  • Multiple Cause of Death Files

  • These files were created by the National Center for Health Statistics (NCHS) and include underlying, immediate, intermediate, and contributing causes of death and demographic data. Each record may include up to 20 causes of death derived from California death certificates.  All causes of death are coded according to the International Classification of Diseases.  These files include certificate numbers, but do not include names or other personal identifiers.  These files can be linked to other death files using the certificate number. A list of variables for these files may be obtained at the NCHS or the Centers for Disease Control and Prevention.
