Undercoverage statistics show how gaps in essentials like nutrition, safe water and sanitation, and healthcare can add up—especially when cost or life circumstances get in the way. Across the page, you’ll see differences by region and group, from child poverty in the U.S. and sub-Saharan Africa to adults reporting they can’t afford needed care. We also explore barriers linked to disability and education, plus limits that prevent people from taking time off for medical appointments.
