Index terms

Derived variable note:

Age, in completed years, at the time of interview. Calculated from the date of birth held in the sample administration database and the interview date. This is conceptually different from dvage which measures the age at the time eligibility for the interview is determined (typically at the time of household enumeration). Uses current and previous wave values of dvage to compute doby_dv where missing. Recorded to missing sample members whose interview outcome is inconsistent with the suggested age +/- one year. DOB month dobm_dv is made available in UKDS SN 6931 only. DOB day (dobd_dv) is made available in UKDS SN 6676 only.

Uses intdatd_if, intdatm_if, intdaty_if, intdatd_dv, intdatm_dv, intdaty_dv, doby_if, dvage, doby_dv, dobm_dv, dobd_dv.
