Codes and Frequencies
BIOSTOVEYN indicates whether the household has an improved biomass stove, which relies on traditional fuels (such as wood) but is designed to reduce energy consumption and harmful smoke emission. The related variable BIOSTOVENUM reports the number of improved stoves owned by the household.
The information in BIOSTOVEYN 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").
Comparability — Index
BIOSTOVEYN differs slightly across samples in question wording. Most surveys asked whether the household "had" this amenity (which could imply access without ownership, as with tenants), but some (noted below) asked whether the household "owned" the "foyer ameliore [improved fireplace]."
Comparability - Standard DHS
BIOSTOVEYN is a country-specific household variable not included in the standard DHS questionnaire.
Comparability — Benin [top]
The Benin 2006 survey asked if the household "owned" an improved stove. Such wording could exclude renters or other tenants who can use household amenities but do not own them.
Comparability — Mali [top]
The 2018 Mali survey asked if the household had "an improved fireplace."
