![]() ![]() ![]() The wealth index is particularly valuable in countries that lack reliable data on income and expenditures, which are the traditional indicators used to measure household economic status. Developed by The DHS Program with partial funding from the World Bank, the DHS wealth index also allows governments to evaluate whether public health services, vaccination campaigns, education, and other essential interventions are reaching the poorest. The wealth index allows for the identification of problems particular to the poor, such as unequal access to health care, as well as those particular to the wealthy, such as, in Africa, increased risk for infection with HIV. Wealth is a household characteristic that often has a large affect on health. The wealth index is presented in the DHS Final Reports and survey datasets as a background characteristic. DHS separates all interviewed households into five wealth quintiles to compare the influence of wealth on various population, health and nutrition indicators. Generated with a statistical procedure known as principal components analysis, the wealth index places individual households on a continuous scale of relative wealth. The wealth index is calculated using easy-to-collect data on a household’s ownership of selected assets, such as televisions and bicycles materials used for housing construction and types of water access and sanitation facilities. The wealth index is a composite measure of a household's cumulative living standard. ![]()
