Rural areas have low population densities and are located in open country settings. Rural development aims to improve social, economic, and cultural conditions in villages and small towns through initiatives to build infrastructure, provide public services, boost communication, and enhance health, education, living conditions, and employment opportunities. A large percentage of the world's and India's poor live in rural areas, where lack of adequate sanitation, nutrition, safe water, and other factors have negative health impacts according to the World Health Organization.
