The « Trajectories and Origins 2 » (TeO2) survey makes it possible to establish national statistics on the diversity of populations in metropolitan France and to study how migratory origins influence the future of individuals.

It seeks to measure the impact of origins on access to the main goods that define each person's place in society: housing, education, language skills, employment, public services and social benefits, health, social and family relations, nationality, citizenship, etc.

The TeO2 survey allows to identify the “third generation”, particularly those of non-European origin. To complete this sample and to enable studies on the situation of third generations of non-European origin, Ined and Insee have added a complementary section to the TeO2 survey, identified under the acronym “TeO2 - G3”.

This additional TeO2 - G3 section consists of administering the same questionnaire as the TeO2 survey to an extended sample of people with at least one immigrant grandparent of non-European origin.

INSEE and INED are co-producers of the Trajectories and Origins survey for its first and second editions (TeO1 2008-2009 and TeO2 2019-2020). Within this framework, the two institutes have constructed a nomenclature of countries and nationalities to enable researchers and public statisticians to conduct their work on immigration in France. This classification aims to provide relevant groupings from the point of view of migratory waves and socio-cultural profiles . In so doing, its implementation and dissemination beyond the TeO2 survey should allow for better comparability of results from one study to another.

The TeO2 survey, like the first edition, focuses on the social trajectories of individuals and on the analysis of integration processes. The questionnaire therefore focuses on individual trajectories and includes retrospective elements (educational, professional, family and residential trajectories). Particular attention is paid to the collection of the elements that make up the geographical, social, cultural or residential origin.

Each sphere of the respondent's life is examined in depth in a special module. With the exception of a minor change in the titles of the modules, their list is identical to that of the first survey. As in the 2008-2009 survey, the main themes covered are

• the family and social environment (family environment, marital history, social relations),

• access to the various resources of social life (education, housing, employment, health, civic life),

• the different dimensions of origins and belonging (links with the country of origin, religion, languages, self-image and the way others see them).

The theme of discrimination is addressed in a cross-cutting manner in different modules. The grounds for discrimination recorded can be diverse: origin, but also gender, religion, disability, sexual orientation, place of residence, etc.

Compared to TeO1, developments have been made to allow new studies on all the themes of the questionnaire and in particular on the following subjects

• the consequences of pre-migration characteristics on the socio-economic trajectories of migrants;

• the impact of migrants' legal trajectories (administrative status) on their integration conditions;

• the health behaviours of immigrant populations and their integration into the French health care system;

• the social trajectories of the grandchildren of immigrants (the « third generation » ).

Concepts :

Third generation: a third-generation descendant of immigrants is a person born in France with at least one parent descended from immigrants and no immigrant parents. They therefore have between one and four immigrant grandparents.

Person living in ordinary housing

The survey is based on a sample of grandchildren of non-European immigrants (third generation) aged 18 to 59.
