So-called "ordinary" households, i.e. excluding households living in collective dwellings (nursing homes, prisons, hospitals, etc.) and living in mobile accommodation (boatmen, the homeless, etc.) for the sampling of households entering the survey. However, the longitudinal aspect of the survey deals with individuals who have left to live in retirement or nursing homes.

The survey covers metropolitan France.

However, for reasons of cost, the sample of wave 1 (2004-20005) to wave 3 (2008-2009) focused on the following regions:

- Nord-Pas-de-Calais ;
- Île-de-France ;
- Aquitaine;
- Rhône-Alpes;
- Pays de la Loire;
- Languedoc-Roussillon;
- Provence Alpes Côte d'Azur (since wave 2 in 2006).
