The two data files are SPSS for Windows system files (hence the suffix of .SAV; see SPSS 1998).

The files contain data from the 1991 British Social Attitudes Survey (carried out by Social and Community Planning Research [SCPR, since renamed the National Centre for Social Research (http://www.scpr.ac.uk/)]; Jowell et al., 1992) and from the 1986 Social Change and Economic Life Initiative surveys (Gallie et al. 1994). The authors are grateful to Roger Jowell of SCPR and to Duncan Gallie for permitting them to make use of the BSAS and SCELI data. Further details of the data in the two files are given on the specific web pages listed above.

Note that analyses of data from the two surveys should, strictly speaking, apply weights to the data to take account of the sample design. However, for simplicity, weights have not been applied in the analyses described in the text within the book, and consequently no weighting variables have been provided in either dataset.

The full sets of data from both these surveys can be obtained by academic users from the Data Archive at the University of Essex (http://www.data-archive.ac.uk/). The authors hope that readers will find that the selection of variables provided in each dataset allows them to carry out some interesting analyses over and above the example analyses described within the text of Chapter 9 of the book.
