National Statistics Office of India under Ministry of Statistics and Programme Implementation follows policy of open access to microdata from its extensive surveys and censuses. Our web-based cataloguing portal, powered by the National Data Archive (NADA) software from the International Household Survey Network(IHSN),provides researchers, policymakers, and the public with seamless access to detailed survey metadata and datasets. This gateway to official statistics is designed to support evidence-based research and informed decision-making through transparent data dissemination.

This system serves as a portal for researchers to browse, search, and download relevant census or survey documents and metadata. The Microdata Archive provides web based access to the complete metadata and unit level data of over 178 surveys and censuses.
