Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
CHICKYN indicates whether the household owned chickens. In some cases, the question referred to other domestic fowl, as well; see Comparability. The complementary variable CHICKNUM reports the number of chickens owned by the household.
The information in CHICKYN is taken from the household record, linked to the record of the woman respondent. This information applies to household residents, not temporary visitors, so researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2").
