How does access to sanitation vary across the world? World Vision’s goal is that by 2030 all communities located within our development areas worldwide will have access to safe water (defined as a 30-minute or less round-trip walk to the water source), adequate sanitation, hand-washing facilities and menstrual hygiene facilities, as well as hygiene promotion and behaviour change. Billions of people around the world are continuing to suffer from poor access to water, sanitation and hygiene, according to a new report by UNICEF and the World Health Organization. This improvement occurred despite strong population growth over this period. Related chart – a global map of the number of people who use safe drinking water is available here. How many die from diarrheal diseases each year, and how can we prevent them? What determines levels of clean water access? This means that over these 25 years the average increase of the number of people with access to improved drinking water was 107 million every year. At the same time the share of people practicing open defecation halved, from 27 percent to 13 percent. Increasing global temperatures are one of the main contributors to this problem. By 2015, this had nearly halved to 666 million. In the last year for which we have data (2014 to 2015) the speed was close to the 25-year average: 296,831 gained access to drinking water on average every day in this period. In the map here you can explore the number of people without access to improved water sources across the world. Groundwater from over 30 million access points supplies 85 per cent of drinking water in rural areas and 48 per cent of water requirements in urban areas. What share of people have access to an improved water source? A water project, like a new well, can transform a child's life. In the chart we see that it ranks as a very important risk factor for death globally. And hence, a quarter of India’s population is affected by a severe drought. More than double that number are at risk for water contamination from improper wastewater management. Access remains lowest in Sub-Saharan Africa where rates typically range from 40 to 80% of households. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). Available online. What becomes clear is the large differences in death rates between countries: rates are high in lower-income countries, particularly across Sub-Saharan Africa and Asia. If the water source is less than 0.6 miles away and consistently provides Access to safe drinking water is measured by the percentage of the population having access to and using improved drinking water sources. By 2015, this had fallen to 20%.In contrast, Sub-Saharan Africa was host to 22% of those without water access in 1990; by 2015 this had increased to nearly half of the global total. Its politics and governance therefore has a much stronger influence than average income. By 2015, this had nearly halved to 666 million. This was 2.2% of global deaths. Access is defined by distance and amount of water available. Since nearly all points lie above this line, with very few exceptions — notably Palestine — access to improved water sources is greater in urban areas relative to rural populations. And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Mozambique which has a similar income levels has just over 50% access. An estimated 1.2 million people died as a result of unsafe water sources in 2017. A lack of access to clean water negatively impacts human well-being along with social and economic development. World Development Indicators Metadata. The infrastructural challenges of developing municipal water networks in rural areas is also likely to play an important role in lower access levels relative to urbanised populations.
