As of 2022, four percent of the world's population only had access to unimproved drinking water services. Unimproved drinking water comes from unprotected dug wells or unprotected springs. Regionally, Sub-Saharan Africa and Oceania had the lowest share of populations with access to at least basic drinking water services.
