Présentation de l'opération

Organisme producteur :

Insee. Direction des statistiques démographiques et sociales (DSDS)

Type d'opération :


Objectifs :

The aim of this consumer survey, named CAMME in France, is to collect information on consumer behaviour and expectations in terms of expenditure attitudes and savings.

This survey is carried out each month by the Member States of the European Union.

It also measures cyclical trends as perceived by households (changes in prices, etc). The CAMME survey thus contributes to the evaluation of the French economic outlook.

This survey permits us to calculate the consumer confidence indicator, which is regularly referred to in the media.

Thèmes abordés :

The survey collects information on the opinions households have of :
- the general economic situation in France (unemployment, inflation) ;

- their own financial situation ;

- their intentions in terms of saving and expenditure.

For each of these points, households are asked their opinions of past and future trends (over a period of twelve months before and after the date they are surveyed).

In addition, the CAMME survey is used for complementary modules comprising a maximum of twenty questions and addressing specific topics such as environment, wellness and housing conditions.

Période et mode de collecte :

Until 2007, the survey was conducted each month except August. Since 2008, it has been conducted every month.

Households are surveyed in three consecutive months.

The survey is conducted by telephone. Fieldwork for the monthly surveys takes place in the first three weeks of each month.

Historique :

The survey set up in 1958 by INSEE with a threefold purpose :

- to collect the opinions of households on short-term changes in cost ;

- to study households’ spending intentions ;

- to study their holidays.

Initially, the survey was carried out half-yearly, and then from 1965 four-monthly.

In 1972, the survey was conducted on a identical basis within the European framework. Since that date, the European Commission has set up an European system for business and consumer surveys to which the Member States of the European Union now contribute.

In January 1987, the CAMME consumer survey was launched in France. The questionnaire used is part of the former four-monthly survey, adapted to European needs.

In 2003, the CAMME survey was restructured with the following three aims :

- to adapt the questionnaire to new European requirements ;

- to improve upstream and downstream statistical processing ;

- to modernise computerised processing.

Two new quantitative questions on prices were introduced : opinion given on the development of consumer prices over the last 12 months and in the next 12 months.
The purpose of the current consumer survey is twofold : first, to collect information on households’spending and savings intentions, and second, to assess their perception of the factors influencing these decisions.

Plan de sondage :

Until June 2012, the sample consisted of the telephone numbers of subscribers listed in the France Telecom directory (18 million subscribers).
The following were excluded : households without a telephone, those registered to the “red-list” (opposed to the dissemination of their phone number) or to the “orange-list’ (anti-canvassing list) and people equipped solely with a GSM telephone (cellular or mobile).

From summer 2012, the sample consists of households registered to the French Local Residence Tax (“Taxe d'habitation”). The households whose phone number appears in the white pages directory are surveyed.
This new sampling framework has improved the coverage of the population in particular of the younger members but it remains incomplete because ex-directory numbers can not be selected.

The sample comprises three sub-samples :

- 1,100 households being surveyed for the first time ;

- the households surveyed for the second time ;

- the households surveyed for the third and last time (3rd wave).

Méthodologie :

Each new sub-sample is questioned for three consecutive months. 

However certain households are not surveyed : impossibility to contact them, refusals… In general about 1,900 questionnaires are completed each month.
A methodological operation was carried out in April 2008 to measure the impact of survey base coverage bias. 

The result was that the survey provides data of sufficient quality for short-term analyses.

Autres spécifications :

The Monthly consumer confidence survey (CAMME) is one of the 11 business and consumer surveys carried out by INSEE.

It is therefore part of the harmonised European Union programme of business and consumer surveys to which the Member States of the European Union contribute. The questionnaires and processing methods are in line with each other.
