This project will develop and promote a Hygiene Index (HI) that will serve as monitoring tool for the hygiene and sanitation performance of cities. The index will reveal how targeted interventions over the years have led to improvement in the hygiene and sanitation situation, thereby helping government stakeholders measure the current hygiene status of the cities. It will help policymakers identify the areas in need of improvement and the associated investments required. As of 2018, the survey for 25 cities is complete. Each city is ranked on a series of parameters including water supply, toilet coverage, solid waste management, behavior change communication and health outcomes.
