Definition
ROOMCOOLER indicates whether the household has a room cooler, also known as an evaporative cooler, swamp cooler, desert cooler, or wet air cooler. This device cools the air inside a dwelling through the evaporation of water, requiring much less energy than air conditioning but demanding regular replenishing with water.
The information in ROOMCOOLER 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 (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
