National Digital Archive of Datasets (NDAD)

The National Digital Archive of Datasets (NDAD) preserves and provides online access to archived digital datasets and documents from UK central government departments.

Database management systems are used to gather, store and analyse large amounts of statistical information. This information influences and affects policy and legislation at the highest level, so the databases stored and preserved by NDAD are important evidence of the decision-making processes of UK government.

These documents are free of charge to download.
