Enquête sociale et de santé 1998 (1998 Québec Health and Social Survey)

Notice to User

The Institut has made the microdata file on the Enquête sociale et de santé 1998 (1998 Québec Health and Social Survey) (ESS 98) available to outside analysts and researchers. Under the terms of its policy on the use of the microdata files on its surveys, the Institut had to process the ESS 98 microdata file with a masking treatment in order to reduce the risk of respondent identification.

To apply for access to the ESS 98 microdata file, researchers must enter into a user contract. For help in filling out the contract form, researchers may consult various PDF documents on this site: 

Special attention must be paid to the masking so as not to limit the analytical potential of the file.

Users of the ESS 98 file should start off by reading the Note on masking in the user guide. The note sets forth the impacts of masking, some of which can significantly affect some of the file variables.

Subsequently, the user, as regards the masking, should consult the following sections:

  • Notes explicatives sur les données modifiées (Explanatory notes on the data modified)  in the Code Book.
  • Notices explicatives sur les indices modifiés (Explanatory notes on the indexes modified) in Volume 2: Definition and Composition of Indexes.

The tables in these two sections present the data and indexes modified or removed following the masking of the file. For more detailed information regarding the masking, consult Appendix 9 of Volume 1 : Appendices.
