World Bank Microdata Library

The Microdata Library catalogues thousands of surveys from the World Bank, national statistical offices, and international organisations. For India, it contains NFHS rounds, Enterprise Surveys, Global Findex data, and various impact evaluations and living standards surveys. The key value proposition: many of these datasets are available as anonymised microdata for researchers who register. This is where you find the raw survey responses, not just the published tables. The API provides metadata; actual microdata access requires registration and sometimes additional approval from the data owner.
