The global sanitation crisis is one of the largest and most overlooked health emergencies in the world today. Toilets save lives because they keep human waste away from people, food, and water, which stops the spread of deadly diseases. As of 2024, around 3.4 billion people still lack safely managed sanitation, and unsafe sanitation is linked to the deaths of hundreds of thousands of people every year. A safe toilet is not a luxury. It is one of the most cost-effective tools we have to protect human life and dignity.
Human Concern International works to close this gap by funding toilets, clean water, and hygiene programmes for vulnerable families. This guide explains the scale of the sanitation crisis, why toilets save lives, who is most at risk, and how your support creates lasting change. The figures here come from the World Health Organization, the UNICEF Joint Monitoring Programme, and the WHO.
The global sanitation crisis is the failure to give billions of people a safe and private place to use the toilet. Safely managed sanitation means an improved toilet that is not shared and where waste is treated or safely contained. As of 2024, only 58 percent of the world used a safely managed service, which leaves about 3.4 billion people without one. Among them, 354 million people have no toilet at all and practise open defecation.
Indicator | Figure (2024) |
|---|---|
People using safely managed sanitation | 58 percent of the world |
People without safely managed sanitation | 3.4 billion |
People with no toilet (open defecation) | 354 million |
People who gained safe sanitation since 2015 | 1.2 billion |
Deaths each year from inadequate WASH | 1.4 million |
Deaths each year from unsafe sanitation | 564,000 |
Progress is real, but far too slow. Between 2015 and 2024, about 1.2 billion people gained safely managed sanitation, and global coverage rose from 48 percent to 58 percent. Even so, no world region is on track to reach safe sanitation for all by 2030. Progress would need to rise sixfold to meet that goal.
Toilets save lives by breaking the chain of disease that spreads through human waste. When waste is left in the open, it contaminates water, soil, and food, and it passes infection from person to person. Each year, around 1.4 million people die from causes linked to unsafe water, sanitation, and hygiene. Unsafe sanitation alone accounts for about 564,000 of those deaths, most of them from diarrhoeal disease.
Poor sanitation spreads a wide range of illnesses, including:
Good sanitation has a direct and measurable effect. Better water, sanitation, and hygiene can cut diarrhoeal disease by 25 to 35 percent. For a young child, that difference can mean life or death. Diarrhoea is still one of the leading causes of death in children under five, and most of these deaths can be prevented with a safe toilet and clean water.
The sanitation crisis hits the poorest and most vulnerable people hardest. Low-income countries carry the heaviest burden, where open defecation rates are about four times the global average. Rural communities and crowded informal settlements in cities often have no safe toilets at all. The people most at risk include:
Women and girls carry a hidden cost. Without a safe and private toilet, many girls miss school during their periods or stop attending altogether. A lack of toilets in schools and health centres lowers attendance and makes care harder to deliver. Safe sanitation protects health, education, and dignity at the same time.
The cost of poor sanitation reaches far beyond illness. It holds back children, families, and whole economies. The table below shows how the harm spreads.
Area | Impact of poor sanitation |
|---|---|
Health | 1.4 million deaths a year from inadequate WASH, plus cholera, typhoid, and worms |
Children | Repeated infection causes malnutrition and lifelong stunting |
Education | Girls miss school without private toilets, which lowers attendance |
Economy | Lost productivity and high health costs slow national development |
Dignity | Open defecation strips away privacy, safety, and self respect |
The economic case for toilets is strong. A World Health Organization study found that every 1 dollar invested in sanitation returns about 5.50 dollars through lower health costs, higher productivity, and fewer early deaths. Few global health investments deliver a better return.
Solving the sanitation crisis does not need complex technology. It needs safe toilets, clean water, and simple hygiene, delivered where they are needed most. Proven solutions include:
Human Concern International responds to the sanitation crisis by funding toilets, water points, and hygiene support for families in vulnerable regions. These projects reduce disease, protect children, and restore dignity to whole communities. In Islam, providing clean water and sanitation is a powerful form of Sadaqah Jariyah, an ongoing charity that keeps rewarding the giver every time someone benefits. When you fund a toilet or a water source, you help save lives today and for years to come. Donate today and give a family the safe toilet and clean water they need.
As of 2024, about 3.4 billion people lacked safely managed sanitation, which is more than 4 in 10 people worldwide. Of these, 354 million people have no toilet at all and practise open defecation. The gap is largest in low-income, rural, and conflict-affected areas.
A toilet saves a life by keeping human waste away from people, food, and water, which stops the spread of deadly diseases. Unsafe sanitation is linked to about 564,000 deaths each year, mostly from diarrhoea. Better sanitation and hygiene can cut diarrhoeal disease by 25 to 35 percent.
Poor sanitation causes and spreads diarrhoeal diseases such as cholera, dysentery, and typhoid, along with hepatitis A and polio. It also drives neglected tropical diseases such as intestinal worms, schistosomiasis, and trachoma. In young children, repeated infection leads to malnutrition and stunting.
Women and girls are most affected because a lack of safe and private toilets puts their safety, health, and dignity at risk. Many girls miss school or drop out when there is no private toilet to use during their periods. Safe sanitation helps keep girls healthy and in education.
Yes. Funding a toilet, latrine, or water source is widely considered Sadaqah Jariyah, an ongoing charity in Islam. The reward continues for as long as people benefit from the facility you helped build. This makes sanitation one of the most lasting causes a donor can support.
You can help by donating to trusted sanitation and water programmes such as those run by Human Concern International. Your gift funds toilets, clean water, and hygiene education for families who need them most. Every safe toilet protects health, saves lives, and restores dignity.
