Data resources and estimates - Introduction
In this section, you are offered three tools to build dynamically water supply and sanitation data representations in the form of maps, graphs and tables that you can then export.
For each output you can choose the:
- type of data (water or sanitation coverage);
- geographical area you are interested in (country, regional or worldwide);
- level of aggregation (country or group level);
- year(s);
- areas (urban, rural or both).
Once a research has been initiated, related information, documents and links are provided below the map and graphs.
In addition you will find in the documents and links section all country files available with the latest estimates for drinking-water and sanitation. These country files also includes the origin of all data used in the estimates.
Please note that for communication purposes in the JMP 2013 update report, the JMP displays proportions as rounded integers, which together add to 100% for drinking-water and sanitation, respectively. For its database here on the web site, the JMP uses unrounded estimates to achieve greater accuracy when converting coverage estimates into numbers of people with or without access. Any “apparent” discrepancies between the published estimates and those derived from the JMP web site are due to the published estimates appearing rounded to the nearest integer.
The latest JMP estimates tell us:
768 million people do not use an improved source of drinking-water [read more…]
- The world met the MDG target for drinking-water.
- 2.1 billion people gained access to improved sources for drinking-water since 1990. Over 70% of the global progress was achieved through access to piped drinking-water.
- In developing regions, 87% of the population uses an improved source of drinking-water.
- Although 1.2 billion people gained access in the urban areas of the developing world, due to the urban population growth the percentage gain is only 2% since 1990.
- Over 8 out of 10 people who do not use an improved source of drinking–water live in rural areas.
- In Sub–Saharan Africa 63 million more people use an unimproved source of drinking-water in 2011 than 1990, an increase of 24%.
2.5 billion people do not use improved sanitation [read more…]
- Within the developing world (without counting India and China) in 2011, 870 million people have gained access to improved sanitation since 1990, but there is a 12% increase of population using unimproved facilities in this region for the same 21-year period.
- Open defecation rates have decreased from 24% in 1990 to 15% in 2011. Worldwide, 1 billion people practise open defecation, a decline of 244 million since 1990.
- With only 47% of the rural population using improved sanitation, rural areas lag far behind urban areas where the rate is 80%.
- As in the previous 2012 JMP progress report, the 2013 JMP update report also shows that seven out of ten people without improved sanitation live in rural areas.
- The number of people in urban areas without improved sanitation increased by 196 million people between 1990 and 2011 because of urban population growth.
