The PSID Mortality File contains information about all individuals in the PSID who are known to be decedents from the beginning of the study through the most recently available wave of data collection. As described in the Introduction to the Mortality Data User Guide, and as listed in the Mortality Data Codebook, variables include the year in which PSID staff uncovered death information, month/year of death, age at death, the states or countries in which the individual was born and died, and an accuracy indicator for missing death date data. Beginning with the 2005 data release, additional variables were included that document the National Death Index (NDI) matching process as well as complete cause of death information for those cases deemed to be a good match. These NDI variables are currently unavailable.   The Mortality File is designed to be linked to the publicly available individual and family PSID data files available through the PSID Data Center, and identifiers are compatible with these datasets.
