Presented to heads of state and government one week before they met in New York for the United Nations 2005 World Summit, the 2005 Human Development Report shows that while there has been substantial overall progress globally, many individual countries are actually falling further behind, and that the human costs of missing agreed global targets for lifting people out of extreme poverty would include many millions of preventable deaths over the next 10 years. Using the latest country-level data, the Report shows that human development is improving but too slowly to achieve the Millennium Development Goals (MDGs). Concerning the goal to improve access to safe drinking water, the Report concludes: 'Our trend analysis suggests that the target of halving the number of people without sustainable access to improved water sources will be missed by about 210 million people. Another 2 billion people will also lack access to improved sanitation in 2015.'
