What percentage of the world has access to clean water?
Key facts. In 2017, 71% of the global population (5.3 billion people) used a safely managed drinking-water service – that is, one located on premises, available when needed, and free from contamination. 90% of the global population (6.8 billion people) used at least a basic service.
Who is affected by lack of clean water?
Women and children are the most affected — children because they’re more vulnerable to diseases caused by dirty water and women and girls because they often bear the burden of carrying water for their families for an estimated 200 million hours each day.

Why do some individuals lack supply of clean drinking water?
Climate change and an increase in unpredictable and extreme weather is a growing challenge. Long periods of drought affect clean water supplies while flooding can pollute clean water sources and cause outbreaks of disease. The world’s population is predicted to grow to 8.5 billion by 2030 and 9.7 billion by 2050.
Which is the most common way to purify drinking water?
1. Boiling. The simplest and most common method to purify drinking water is to boil it. Heat the water over a stovetop burner or open flame until it reaches a full, rolling boil, and continue to boil for a minimum of five to ten minutes to be safe (the longer the water is boiled, the purer it will become).
