Developing an Equity Index for Water and Sanitation

Monitoring inequality in water and sanitation is essential as the human right is now officially recognized. The preferred metric would focus on the rate of change, but this has not yet been done. We developed an equity index, published in the International Journal of Hygiene and Environmental Health, to measure progressive realization for the human right and fairly compare countries’ progress towards universal access by normalizing rates of change against a benchmark. Using this index, we demonstrate that progressive realization can be achieved regardless of state economic status, development progress, or related factors.
