Nesstar is the online data exploration system used to provide access to a wide variety of datasets held by the UK Data Archive including many large-scale datasets, for example, the Labour Force Survey, and academic surveys such as the British Social Attitudes Survey and the National Child Development Study. It is "a visual data library where you can search, browse and download a selected range of key social and economic data". All visitors to the UK Data Service Nesstar Catalogue can browse study metadata, variable frequencies and use the simple and advanced search options. Registered users can also create simple online cross-tabulations, produce graphs, and download subsets of variables in a variety of formats.
