Service Description: This index is comprised of three equally weighted components: 1) population density, 2) proximity to others in the household and 3) water, sanitation, and hygiene. Three indicators are equally weighted within the proximity to others in the household component: intergenerational households (household has a child less than eleven years old and a person above 60 years old), average number of household members per sleeping room, and adults aged 15 to 49 employed in essential occupations (sales, services, repair, construction, and transportation). Five indicators are equally weighted within the water, sanitation, and hygiene component: soap for handwashing inside the home is unavailable, water for handwashing inside the home is unavailable, household must walk 30 or more minutes roundtrip to collect drinking water, household shares toilet with other households or does not have a toilet, and household does not have piped-in drinking water. Population density is defined as population at the 1km squared level. Indicators within components are combined with z-scores at the 1km squared grid level.
