Entry in the 2011 Urban Water Design Challenge, sponsored by Visualizing.org and Circle of Blue.
Many developing and emerging economies are experiencing huge shifts of people from rural to urban areas. The ability of countries to provide improved sanitation and water services to these new urban migrants is essential. This graphic highlights the relative scale of urbanization between countries (shown by the size of the spheres), the extent of the existing insufficiency of improved sanitation and water services (vertical axis shows number of people without improved sanitation services in the graphic with the blue spheres and the graphic with the green spheres shows the number of people without improved water services – as defined by WHO/UNICEF), and the horizaontal axis shows how well each country is keeping up in providing sanitation and water services to new urban migrants.
Below 100 percent means that people are migrating to urban areas faster than the country can provide these services. Above 100 percent means the country is keeping ahead of the trend and further improving conditions for existing urban residents who are without improved sanitation and/or water services.
