This is a 3-digit variable that represents the number of ducks owned, except for the following codes:
996 = Not interviewed (household questionnaire)
997 = Don't know
998 = No response
999 = NIU (not in universe)
DUCKNUM reports the total number of ducks owned by the household.
Users should be careful to distinguish this variable from DUCKHOME (the number of ducks on the homestead, which may or may not be owned by the household).
Enumerators were instructed to code "Don't know" or "No response" cases as -88 and -99, respectively. However, in some samples, a select number of enumerators recorded an unexpectedly high number of 88 and 99 values for livestock variables. We believe the majority of these cases were intended to represent "don't know" and "no responses" instead of indicating a number of livestock. IPUMS has recoded these cases to "Logical edit - missing".
The question associated with this variable was included in the household questionnaire.
Comparability — Index
DUCKNUM varies slightly across samples in question wording. Most samples asked about the ownership of ducks specifically, but some samples included other birds in the same question.
Comparability — Niger [top]
The Round 1 and 2 surveys ask about the number of ducks and geese owned by the household.
Comparability with IPUMS-DHS
DUCKNUM in IPUMS-PMA is similar to the variable DUCKNUM in IPUMS-DHS. Universe differences between the two variables and variations in the specific question wording may affect comparability; please see the Survey Text and Universe Tab of the IPUMS-DHS variable for more information.
