The World Bank's ID4D program has published the third annual update of the Global Dataset on the estimated number of people around the world without an officially-recognized ID - 1.1 billion - including 357 million in South Asia and 82 million in East Asia and the Pacific.

The dataset draws on publicly available data on adult registration rates and data submitted by national ID agencies themselves, as well as birth registration rates from UNICEF's database. It also includes qualitative data on features of civil registration and ID systems. Some additional commentary on the data and how it can be improved can be accessed on the Information and Communication for Development (IC4D) blog.
