2.1 Global coverage

Table 2.2 shows the numbers of people with and without access to improved water supply and sanitation, both globally and by region, together with percentage coverage. The corresponding information for urban and rural areas is also given. Estimates are provided for both 1990 and 2000. The percentage of the population on which the estimates for each region are based is shown in italics above each section, and reflects the availability of data. Overall, data were available for 76% of the global population for 1990, while 89% were represented in the 2000 figures.

One of the aims of Assessment 2000 was to improve the quality of water supply and sanitation coverage data. However, when comparing estimates, and especially when interpreting trends over time, it should be recognized that more data were available for a greater number of countries for the year 2000 than for 1990.

Globally, 1.1 billion people are without access to improved water supply and 2.4 billion are without access to improved sanitation. Figures 2.1 and 2.2 show where the unserved population is found. For both water supply and sanitation, the vast majority of those without access are in Asia.
