The Housing characteristics survey (ECM) is organised by the National Institute of Statistics and Economic Studies (STATEC).
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 objective of the Housing characteristics survey is to gather information about the characteristics of houses recently acquired by households in order to determine how these characteristics impact on the purchase price as indicated in the notary deed. This information aims at producing a constant quality House Price Index.
The House Price Index, which is published on a quarterly basis, is disseminated via the short term indicator C.
Four times a year, a questionnaire is sent to the persons having recently acquired a house. The selected persons are required to take part in the survey.
In order to respond to the Housing characteristics survey, the selected person must first have received an invitation by post.
The questionnaire for the survey must be filled in by the deadline specified in the invitation letter.
The STATEC invitation letter contains:
Respondents should only fill in one questionnaire (either the online version via MyGuichet.lu, or the hardcopy (paper) version).
If you experience any problems with the questionnaire, please contact STATEC.
The questionnaire is available in Luxembourgish, French, German and English. The choice of language is made directly in the 'Forms / Online services' section. Just click on one of the 'LU', 'FR', 'DE' or 'EN' tabs to start the questionnaire in your preferred language.
