Présentation de l'opération
Organisme producteur :
Insee. Direction des statistiques démographiques et sociales (DSDS)
Type d'opération :
The Permanent Demographic Sample (EDP) is the first large-scale socio-demographic panel established in France to study the birth rate, mortality, relationships, geographical migrations within the national perimeter, social and professional mobility and the potential interactions between these different phenomena. There are two possible approaches to studying these dynamics: surveying people on their past experiences or, using a panel, actually tracking people and accumulating information over time. The latter approach, that of the Permanent Demographic Sample, takes longer but yields information which is more precise and more reliable, free from the potential bias of memory. Thanks to its size, the Permanent Demographic Sample allows detailed analyses which can take account of differences between generations and differentiate the various levels of education, background etc.
Thèmes abordés :
- Birth rate; - Mortality; - Marriages and partnerships; - Social origins; - Family situation; - Qualification and level of studies; - Profession; - Status of activity; - Housing; - Place of residence.

Périodicité de l'opération :
The Permanent Demographic Sample was established in 1967. It comprises information taken from the official publications of the registry office for births, marriages and deaths since 1968, along with census information from 1968, 1975, 1982, 1990 and 1999. Information derived from the annual census surveys is also integrated. Due to restricted resources, registry information was not systematically integrated for all members of the sample group between 1982 and 1997.
Plan de sondage :
The sample is selected by a simple random process, based solely on a person's date of birth, in line with the amended decree of May 23rd 1984. The sample corresponds broadly to a survey of 1% of the population (4 dates of birth in the year). A decree of December 21st 2006 authorised a quadrupling of the sample size (16 dates of birth).
The general principle is to record the information featuring in the civil register or in census returns for all persons born on one of the designated EDP days. All persons born in France on one of these days are integrated into the EDP at birth, and the information given on their birth certificate is recorded. Other residents, those not born in France, are integrated into the EDP after each census, on the basis of information taken from census declarations. Once a person is registered in the Permanent Demographic Sample, any new information concerning them is added to their records. This includes events recorded on the civil register (marriages, births, deaths) and census information (details of the person, their housing and, where relevant, those living at the same address: partners, parents, children). Data comparison is carried out within the rules stipulated in Decree n°84-393 of May 23rd 1984, by agreement with the National Commission for Information Technology and Liberties (CNIL). Data concerning deceased individuals for whom a death certificate has been received by INSEE will remain in the EDP. The sample will thus continue to grow over the years. Data storage and access to information which has had all identities removed are governed by strict conditions intended to guarantee confidentiality.
