The 1991 Census saw the release of 4 SARs files as outlined below. Research using the 1991 SARs has covered a wide range of areas in a number of different disciplines including sociology, human geography, economics and social statistics. Many users of the 1991 Individual SAR have exploited the large sample size and relatively detailed geography to look at social differences between sub-populations (especially ethnic groups) and between geographical areas. Users of the 1991 Household SAR have exploited the hierarchical nature of the data to look, in particular, at various aspects of household and family structure and inter-relationships within households. More detailed information on each of these files can be accessed through the menu on the left or through the respective links on this page.
