SILC 2025 survey
Last update
A survey on household income and living conditions (SILC) 2025 is organised by the National Institute for Statistics and Economic Studies (STATEC) from 15 May 2025.
STATEC is a state administration under the authority of the Ministry of Economy, which enjoys scientific and professional independence. Its mission is to collect, analyse and disseminate data on Luxembourg's economy and society in a neutral manner.
The purpose of the SILC survey is to collect data on:
- household composition;
- housing and related costs;
- material conditions;
- work and professional status;
- income;
- well-being;
- health;
- participation in social life;
- energy and the environment.
Using the socio-economic information collected by the SILC survey, measures to combat poverty, inequality and social exclusion can be developed, adapted or implemented.
The selected participants are required to take part in the survey once a year for 4 years running. This follow-up makes it possible to better understand and analyse changes in the living conditions of households in Luxembourg.
Who is concerned
The SILC survey is aimed at:
- households in Luxembourg; and
- the individuals who form them.
A participant is randomly selected from the National Registry of Natural Persons. All the members of the participant's household are invited to take part in the survey.
All persons living in the household fill in their answers to the survey in a single form.
Prerequisites
In order to respond to the SILC 2025 survey, the household must first have received an invitation by post.
Deadlines
The questionnaire for the SILC 2025 survey is available from 15 May 2025. Responses must be submitted via the electronic form by 15 September 2025 at the latest.
How to proceed
Responding to the questionnaire
You can access the questionnaire by using the unique access code assigned to the household and stated in the mail received by post.
The questionnaire is available in Luxembourgish, French, German and English.
The survey questionnaire includes:
- questions on the household as a whole; as well as
- questions which are addressed to each member of the household individually.
The information to be filled in relates to:
- the living situation of the members of the household at the time of the survey;
- the income received in 2024.
If possible, the member of the household who is most familiar with housing expenses should answer the household part of the questionnaire. Each member of the household should answer the part of the questionnaire that applies to them.
There are 2 ways to complete the questionnaire:
- with authentication on MyGuichet.lu by using:
- a LuxTrust product;
- a Luxembourg electronic identity card (eID); or
- an eIDAS-compliant means of identification from another European country;
- without authentication on MyGuichet.lu.
The method with authentication is to be preferred because you can save the questionnaire in your private MyGuichet.lu eSpace and fill it in easily at your convenience without any time constraints.
If using the method without authentication, you must complete the entire questionnaire in one go, and it is not possible to save your answers or resume the questionnaire at a later date. However, the maximum time required to complete the questionnaire may not exceed 2 hours.
You can contact STATEC for:
- any questions or requests for help concerning problems with the form;
- the assistance of an interviewer to complete the questionnaire.
To do so, you can contact STATEC:
- by email: silc@statec.etat.lu; or
- by phone at +352 8002 9000 (toll-free number) from Monday to Friday between 10.00 and 12.00 and between 12.30 and 14.00.
