 According to the Joint Monitoring Program of the World Health Organization and UNICEF, in 2004 the share of population which was connected to an improved water source varied from 54% in Haiti to 100% in Uruguay.All together, 50 million people or 9% of the population of Latin America and the Caribbean did not have access to improved water supply, and 125 million or 23% did not have access to improved sanitation.Increasing access remains a challenge, in particular given the poor financial health of service providers and fiscal constraints on behalf of central and local governments.
