The given bar charts compare the proportions of people who had access to safe drinking water and the levels of water purity in separate countries, namely Australia and South East Asia between 1990 and 2010. Generally, in terms of access to clean water and water purity, Australians consistently outpaced South East Asia, while the number of people who were provided with water showed a gradual increase, the quality of water dropped marginally in South East Asia.
As can be easily seen from the graph, in 1990, eight out of ten Australians were supplied with clean water and the number went up gradually to nearly 100% over the next 20 years. By contrast, roughly 40% of people coming from South East Asia had access to safe drinking water in the first year before receiving a two-fold increase in the year 2010.
Turning to the other noticeable points, as for the cleanliness of the water, in Australia, approximately 70% of the water was classified as clean in 1990, and the figure increased by 5% in the next 20 years. From a much lower level (40%), water purity in South East Asia; however, decreased negligibly to 38% in the last year, less than half the level of water cleanliness in Australia.
