How the Data Files are Provided

All data are provided in SAS, SPSS¹ and STATA (Version 8) formats².

The DVD also includes extensive documentation of the data, including coding frameworks, marked-up questionnaires and variable frequencies. Changes to the data files between Release 5.1 and Release 6.0 are listed in Appendix 2. Changes to the data files between earlier Releases are listed here.

The data files can be transferred to other statistical packages using StatTransfer, DBMS Copy, or any other data conversion package of your choice³. You may need to restrict the number of variables to be included in your transferred datasets due to the limitations on the number of variables imposed by some other packages.

Endnotes:

1	SPSS portable files provided on previous releases are no longer provided on the DVD but can be obtained by special request.
2	You will need to use STATA SE as there are more than 2047 variables in the datasets. Suitable memory and maxvar values are provided in "Readme 60.pdf" on the DVD.
