Measuring Water, Sanitation, and Hygiene in a Census

Introduction

In 2010, the United Nations General Assembly adopted Resolution 64/292, establishing a basic and universal human right to water and sanitation. Water, sanitation, and hygiene (WASH) practitioners have responded to that call, developing over 220 different WASH measurement frameworks and tools in the 10 years that have passed since the adoption of Resolution 64/292 (Ajroud et al., 2020; Schweitzer et al., 2014).

This technical note discusses advances in the measurement and reporting of WASH and provides actionable guidance for National Statistical Office (NSO) experts to follow as they prepare their census questionnaire.
