Definition
HMMILL indicates whether the household has a hammer mill, a machine used to break down material through repeated hammer blows. Farmers may use hammer mills to break grain into coarse feed for livestock.
The information in HMMILL is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
