At the beginning of the new millennium, world leaders gathered at the United Nations to shape a broad vision to fight poverty in its many dimensions. That vision, which was translated into eight Millennium Development Goals (MDGs), has remained the overarching development framework for the world for the past 15 years. As we reach the end of the MDG period, the world community has reason to celebrate. Thanks to concerted global, regional, national and local efforts, the MDGs have saved the lives of millions and improved conditions for many more. The data and analysis presented in this report prove that, with targeted interventions, sound strategies, adequate resources and political will, even the poorest countries can make dramatic and unprecedented progress. The report also acknowledges uneven achievements and shortfalls in many areas. The work is not complete, and it must continue in the new development era.
