Nutrition

The basic living conditions that health depends on directly: undernourishment and food insecurity, underweight and overweight, obesity, stunting in children, access to clean water, sanitation and basic hygiene. WHO publishes some indicators separately for urban and rural areas — the gap between them in the table is usually wider than the gap between countries.
