Description

ENDRFDRD indicates the date of the reference period end date for the round. It should be used with the variables ENDRFMRD and ENDRFYRD, which report the corresponding month and year of the end of the reference period, respectively. For most persons in the sample, the date of the round interview is the reference period end date. The end date of the reference period may be prior to the date of the interview if the person is deceased during the round, left the responding unit, was institutionalized prior to the round interview, or left the responding unit to join the military.

ENDRFDRD is a two digit numeric variable; its values represent the date of the month except for the following codes:

96: Not in universe
97: Refused
98: Not ascertained
99: Don't know

Comparability

In 1996, ENDRFDRD only includes eligible persons in rounds 1 and 2 of data collection; in subsequent years, ENDRFDRD is available for all eligible persons. Otherwise, this variable is completely comparable across time.
