A World That Counts: Mobilising the Data Revolution for Sustainable Development was published by the United Nations Secretary-General's Independent Expert Advisory Group on a Data Revolution for Sustainable Development (IEAG) in November 2014.

It was a big bang moment for sustainable development, leading to the establishment of the UN World Data Forum, the Global Partnership for Sustainable Development Data, and data sharing initiatives such as the Global Data Platform and the Data Commons for the SDGs.

While there is still much to be done, in the 10 years since A World That Counts, millions of people have benefited from better data.

This collaborative report explores how the role of data in development has evolved over the last decade, and the impact this has had on people's lives around the world.
