Présentation de l'opération

Organisme producteur :

Insee. Direction des statistiques démographiques et sociales (DSDS)

Type d'opération :


Objectifs :

The aim of the household budget survey (BDF) is to put together the entire household accounts: expenditure and resources of households in France (mainland and overseas departments).

The study of expenditure is the traditional and central purpose of the survey: all household expenditure is recorded, the amount and nature of these expenses, broken down into a classification of about 900 budgetary items (COICOP) compatible with the classification used in the national accounts.

All expenses are covered, including those not associated with the consumption of goods and services (in the sense of the national accounts): taxes and contributions, insurance premiums, major home renovation expenditure, inter-household transfers, purchase of second-hand goods, loan repayments.

As well as expenses per se, the survey also collects information about non-monetary consumption: food produced for own consumption, imputed rentals, etc.

The survey also covers household resources, which include individual income (wages, independent earned income, etc.) and revenue received by the household as a whole (benefits, transfers between households, etc.).

Essentially, the family household budget survey collects monetary data, leaving the more specialised surveys on each item of consumption (transport, housing, leisure, holidays, etc.) to use a more qualitative approach to household behaviour. Nevertheless, in order to illustrate these monetary data, some complementary questions are asked, on the financial situation as perceived by the household.

Thèmes abordés :

Consumption, expenditure, resources, opinion on financial situation, socio-demographic characteristics and equipment.

Champ de l'opération

Champ géographique :

All ordinary households in the whole of France (mainland and overseas departments).

Unité statistique enquêtée :


Périodicité de l'opération :

About every 5 years (1979, 1984, 1989, 1995, 2001, 2006)

Période et mode de collecte :

The 2006 survey was conducted in 6 waves of 8 weeks each, from March 2005 to March 2006.

The Household Budget Survey uses two data collection instruments:

- a questionnaire using CAPI (computer-assisted data collection, broken down over 3 visits), which records income over the last 12 months and major or regular expenditure, also socio-demographic information, characteristics of the dwelling and qualitative questions about the household's financial situation;

- a self-completed diary in which all members of the household aged over 14 record all their expenditure over 14 days.

They can write the amounts in by hand, or attach cash register receipts.

Historique :

1956; 1979 in its present form (1995 for overseas departments).

The BDF survey has existed in France in its present form (5-yearly survey) since 1979. Surveys covering the same topics have existed since 1956 in other forms (permanent surveys, food surveys, etc.).

Until 1995, it was essentially monetary data that were collected; since the 2001 edition, quantities of products consumed have also been collected.

Until 1989, the study of resources was not a declared goal of the survey. However, methodological studies have shown that the "household budget" survey provided a satisfactory measure of income, and it remains the only measurement of income in the overseas departments.

Since 2001, expenditure has been classified according to the European classification. This differs considerably from the French classification used until 1995.

For these reasons, the results of the 2001 and 2006 editions of the survey cannot yet be compared directly with those from previous years.

Plan de sondage :

Sample (random self-weighted sample) of about 20,000 dwellings in Metropolitan France, 5,000 in the overseas departments. The number of households surveyed is ultimately about 10,000 for Metropolitan France and 3,100 in the overseas departments.

In 2006, 10,240 households answered the whole of the questionnaire, which corresponds to 25,364 individuals. The survey of the overseas departments in 2006 covered 3,134 households and 9,118 individuals.
