Water inequality becomes visible when access, quality and impacts are separated by place, income, ethnicity, season and infrastructure.
Unsafe or distant water raises infection risk, collection and care time, and can reduce school or livelihood opportunities. Historical data can reveal a pattern, but current status needs current verification.
Niger provides a named equity case: about 9.5 million people live in extreme poverty, while only 56% of Nigeriens have access to a drinking-water source and 13% to basic sanitation. Drought, weak infrastructure, insecurity and displacement concentrate health, collection-time and livelihood costs on already vulnerable households.
Disaggregated access and sanitation statistics reveal who bears disease, collection time and lost education or livelihood opportunities; a national average alone can conceal that inequity.
Averages can improve while the most excluded group remains unsafe; do not call historical evidence current without checking.
