Status and Descriptive Variables
Mortality status and date of death variables for the graduates (livgrad, deatyr, deatmn) and siblings (xlivsib, xdeatyr, xdeatmn) are updated.
We matched known deaths to the National Death Index to update cause of death measures. In addition to the update, we now use the code of "-4" for measures of the state, the underlying cause, the number of entity-axis and the number of record-axis conditions for cases where we know the participant is deceased but we have yet to have a successful match to NDI data.
