The sampling is a random 3-degrees sampling :

• Drawing of the conurbations
• Drawing of the visits : services x days

• Drawing of the users attending the service on the day of the planned visit.

• A random 80 conurbations with more than 20,000 inhabitants in 2006 was performed. All conurbations with more than 200,000 inhabitants were selected ; conurbations from 20 000 to less than 200 000 people were drawn in proportion to their population and accommodation capacity as measured in the file Finess.

• To achieve the drawing of services by days among the 80 conurbations with more than 20,000 inhabitants, a sampling frame is created. This services database of the scope of the survey was made after a pre-survey realised by a Regional Office and enriched by a telephone survey conducted by investigators in February / March 2011. This survey has enabled for all conurbations of the scope of the survey individuals to gather the information needed to draw visits : fine definition of services from the scope of the survey, average attendance, opening days, type of public welcomed.

• The draw of the users attending the service the day of the scheduled visit is made on site the even day of the visit with a drawing table at their disposal for each service. Four individuals are then interviewed face to face and a maximum of twelve meet a self-administered questionnaire.
