Codes and Frequencies
For sample adults selected to participate in the Adult Functioning and Disability supplement (AFD), AFDCOMPLET reports the record completion status of those sample adults on the AFD supplement.
Differences in how sample adults were selected to receive Adult Functioning and Disability supplement questions varies over time.
In 2011, sample adults in families who received the Family Disability (FDB) questions were also asked additional disability questions as part of the AFD supplement. In 2012, approximately 1/4 of sample adults were selected to receive the AFD questions; some of these persons were also selected to participate in FDB questions Beginning in 2013, families were flagged to either receive AFD or FDB questions. ADB and CDB questions are no longer offered. Sample adults in families not flagged to receive AFD questions will be NIU for all AFD questionnaire items. Beginning in 2018, AFD questions were moved to the sample adult questionnaire and were asked of all sample adults.
Data users may still make comparisons across years, but should be aware of these differences in the universe selection process and use the appropriate weights for their analyses.
