This version of the HRS National Death Index Respondent Matches data set replaces all previously released HRS NDI information products. The data set is made up of three sections:
Section A has two parts: (1) Information created from HRS records submitted to the National Center for Health Statistics (NCHS) for matching purposes. (2) Information from the matching NDI record related to match quality and probabilistic scoring. All records are uniquely identified by Household Identifier (HHID) and Person Number (PN).
Section B contains ICD-9 cause of death information for respondents who died prior to 1999. Records are linked to Section A by Household Identifier (HHID) and Person Number (PN).
Section C contains ICD-10 cause of death information for respondents who died in 1999 or thereafter. Records are linked to Section A by Household Identifier (HHID) and Person Number (PN).
See the NDI User Guide (included in the "Documentation from NCHS" download below) for additional information on the content of each section.
