COOKOILTYPE reports the type of oil the household used for cooking, either typically or within a recent reference period, such as the last seven days. The response "shea butter" refers to a fat extracted from the nut of the African shea tree. "Frytol" is the commercial brand name of a vegetable oil product used for deep frying.

The information in COOKOILTYPE 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").


Along with universe differences, response categories included in COOKOILTYPE vary across samples. To maximize comparability, IPUMS-DHS uses composite coding for COOKOILTYPE, in which the first digit is comparable across samples and the second digit includes detail present in only some samples. For example, all responses for "palm oil" have a first digit of 1, while the second digit distinguishes between red palm oil (code 11) and yellow palm oil (code 12).
