Interviewer instructions
Information on the type of fuel used for cooking is collected as another measure of the socioeconomic status of the household. The use of some cooking fuels can also have adverse health consequences. Remember that this question asks about fuel for cooking, not fuel for heating or lighting. The category 'biogas' includes gases produced by fermenting manure in an enclosed pit. If the household uses more than one fuel for cooking, find out the fuel used most often. If any fuel other than the pre-coded ones is reported as being the main fuel used for cooking, select '96' and specify the type of fuel in the space provided.
