TCM (Common household core)

The Tronc Commun des enquêtes Ménage (TCM) is a questionnaire common to a large number of household surveys carried out by INSEE. It precedes the questionnaire specific to the survey. It consists of a list of fairly general questions that gather information about the inhabitants of a household survey: precise list of the inhabitants of the dwelling, family relationships between them, type of dwelling, occupations, nationalities, qualifications, income, etc. The information is collected in the form of different blocks of questions corresponding to the themes of the different variables.

Set up in the early 2000s, it was computerised (Capi) in 2004 for cross-sectional face-to-face household surveys. In 2017, it was overhauled to adapt to both cross-sectional and longitudinal surveys.

This file brings together the survey files to form a single file. The current version (Leroy 2018) combines files from 29 surveys carried out between 2006 and 2015. Different weightings are possible. An annual weighting is available; others may include the respective weights of the different surveys. Weight sharing is envisaged for multi-residents (Toulemon, Denoyelle 2012).

The full, non-anonymised data will soon be available from the secure data access centre (CASD). An anonymised version will be available from the Archive de données issues de la statistique publique (Progedo Quetelet diffusion).

The file includes the following surveys:

• CVS 2006 to 2015 (Living Environment and Safety)
• SRCV 2006 to 2015 (Statistics on Resources and Living Conditions)
• Housing 2006 and 2013
• Transport and Travel 2007
• Disability-Health Household Survey 2008 (HSM)
• Wealth 2009 and 2014
• Family Budget 2011 (BDF)
