Data Sets
Traditionally, outputs are released in the form of tables of counts at various levels of geography. However, microdata, known Samples of Anonymised Records (SARs) are UK data-sets consisting of samples of individual records from national censuses. These very large datasets resemble survey data and are used for a range of applications by social scientists and policymakers.
The first SAR was released in 1991. In 2001, the SAR system was extended, and it is anticipated that there will be SAR files from the 2011 census.

Famous quotes containing the words data and/or sets:
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“This is certainly not the place for a discourse about what festivals are for. Discussions on this theme were plentiful during that phase of preparation and on the whole were fruitless. My experience is that discussion is fruitless. What sets forth and demonstrates is the sight of events in action, is living through these events and understanding them.”
—Doris Lessing (b. 1919)
