Last week, the United Nations concluded one of the last negotiations on the road to adopting the Sustainable Development Goals in September. We’ve entered the home stretch of a process that has taken more than two years, bringing governments, civil society organizations, and communities together to define the development goals and targets that UN member states will be expected to aim for over the next 15 years.

Earlier this month, the United Nations released a final report on the Millennium Development Goals (MDGs), the framework that has guided global development efforts for the last 15 years. The document examines each of the eight MDGs and finds that “despite many successes, the poorest and most vulnerable people are being left behind.” As one of the first global poverty reduction movements nears its end, the report calls for better data collection practices to create a post-2015 development agenda that can overcome the MDG’s shortcomings.
