In which the answer comes in the form of numbers, statistics
UK Data Archive (UKDA) is a centre of expertise in data acquisition, preservation, dissemination and promotion and is curator of the largest collection of digital data in the social sciences and humanities in the U.K. It is a designated Place of Deposit by The National Archives allowing it to ingest and preserve public records. UKDA is based at the University of Essex. Among its family of services are the History Data Service, Economic and Social Data Service, and UK Census Portal. The History Data Service collects, preserves, and promotes the use of digital resources, which result from or support historical research, learning, and teaching.
Statistics Resources for the United Kingdom, Ireland, France, and Belgium might be of use, as might the data and statistics research guides offered by our expert data librarian, Hailey Mooney.
