Description
ASECOVERH identifies households that are part of the ASEC oversample. For more information, see our technical write-up.
Comparability
This variable is comparable from 1989 forward. In 1976-1988, it is sometimes impossible to distinguish true oversample records from those which we are unable to link between March basic monthly and ASEC files with confidence. For more information, see Flood et al., 2020.
Universe
- All households.
