What should follow the Millennium Development Goals? Adopted at a global summit in 2000, the Millennium Development Goals (MDGs) represent a global compact between rich and poor countries to improve the lives of the world’s poorest people. All 191 UN member states agreed to pursue goals that include reducing extreme poverty, achieving universal primary education, promoting gender equality, and reducing infant mortality. As the 2015 end date of the MDGs approaches, how much progress has the world made? And what should replace them, setting the global development agenda for the next fifteen years? CGD research and analysis provides perspectives on the successes and failures of the original MDGs and the many debates about what should replace them.
