Have you received a letter inviting you to participate in the survey on household income and living conditions?

This survey is organised by the National Institute for Statistics and Economic Studies (STATEC) in order to develop measures to combat poverty, inequality and social exclusion using the data collected.

The questionnaire for the SILC 2025 survey is available from 15 May 2025.

Please note that if you have received an invitation, you must complete the questionnaire by 15 September 2025 at the latest.

You can fill in the questionnaire online on MyGuichet.lu. You can choose between an authenticated or unauthenticated response mode. It is therefore not necessary to have a LuxTrust product or an electronic identity card (eID) to participate in the survey. However, it is recommended to use the procedure with authentication. The procedure with authentication allows you to:

  • save the questionnaire in your private eSpace on MyGuichet.lu; and
  • resume the completion of the questionnaire as you see fit.

For more information on the survey and the online questionnaire please see our dedicated information page.
