Water Insecurity
(Prevalence of Moderate-to-High Water Insecurity)
The Water Insecurity Experiences (WISE) Scales measure human experiences with water and provide insights into whether individuals can reliably access sufficient water for domestic uses. To date, nationally representative water insecurity data have been collected in 40 countries, providing insights into who, exactly, is experiencing water insecurity.
Data for all countries (except Tonga and Mexico) were collected using the IWISE Scale in the 2020 or 2022 Gallup World Poll.
