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.
