To ensure no one is left behind by the next generation of global development goals, a comprehensive mix of robust data is needed to measure progress and guide investments. A recent report coordinated by the Sustainable Development Solutions Network estimates the world will need to spend roughly $1 billion a year to sustain and enhance the statistical systems supporting and evaluating progress towards the Sustainable Development Goals (SDGs), the successors to the Millennium Development Goals expected to guide the development agenda for the next 15 years.

If you were on a mission to improve the plight of humankind, no less, would you care about how many people are living, where they are, and how old they are?

Depending on how closely you pay attention to the OECD, you may have picked up on a subtle but meaningful change in this year’s States of Fragility report.

It shouldn’t come as a surprise that Yemen has collapsed – again. A country that has split and been pulled together before, has the youngest and fastest growing population in the region, is running low on oil and water, and possesses a “personalist” government rather than stable institutions, was on the top of every expert’s list as the fragile state most likely to fail next.

When the first wave of protests erupted in Ferguson, Missouri, following the shooting of Michael Brown in August 2014, it looked as if unrest might spread to other American cities, echoing the “long hot summers” of 50 years before.
