Key Takeaways
- In Ethiopia, only 20.4% of the population had access to safely managed drinking water in 2022.
- Globally, 2.2 billion people (27% of the world population) lacked access to safely managed drinking water services in 2022.
- Unsafe water contributes to 485,000 diarrhoeal deaths annually among children under 5 globally.
