TeO : Survey on Trajectories and Origins - 2019
Data description
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.
To do this, it is essential to study the links between origins and other differentiating factors in French society, notably social background, gender, age, level of education, income and neighbourhood.
The TeO2 survey is a continuation of the first TeO1 survey, with some of the questionnaire's themes expanded (grandparents' origins, administrative history, reactions to discrimination, health, etc.) and new target populations (Chinese immigrants, immigrants from countries with many refugees, children of French nationals living abroad, etc.)
A complementary section of the survey is addressed to the grandchildren of immigrants of non-European origin (the 3rd generation) and is the subject of a separate quality report (TeO2-3G).
Statistical unit
Person living in ordinary housing
Statistical population
The survey is based on a sample of individuals aged 18 to 59 living in an ordinary household in metropolitan France at the time of the survey, with an over-representation of certain populations to ensure sufficient precision in the analyses.
Five sub-populations are distinguished :
-
Immigrants (so-called « first generation » persons);
-
people born in an overseas department or region (Drom);
-
people born in France with at least one immigrant parent (descendants of immigrants, who may also be called « second generation » ) ;
-
persons born in metropolitan France with at least one parent born in an overseas department or region;
-
people who do not belong to any of the above groups (« majority population » ), some of whom have migratory ancestry and are of particular interest to the survey:
-
persons with at least one parent born French abroad, including in a colony (so-called « children of French abroad » );
-
the grandchildren of immigrants (known as « third generation » ), of European and non-European origin, for whom an effort must be made to over-represent them.
Reference area
France métropolitaine
The survey took place from 2019 to 2020.
Comparability - geographical
The data is representative at the national level and calibrated at the regional level, but is not intended to be representative at finer levels.
Comparability - over time and CC2. Length of comparable time series for U
Comparability with TeO1 is ensured but the sample of descendants of immigrants has been extended to cover 18-59 year olds whereas TeO1 only covered 18-49 year olds.
Source data
The sampling frame used for the TeO2 survey is the 2018 Annual Census Survey (ACS 2018), which includes all people living in municipalities with fewer than 10,000 inhabitants enumerated that year (one in five) and about 8% of the population living in municipalities with more than 10,000 inhabitants.
This is the most recent source available. This makes it possible to have recent addresses, and thus to limit the bias and contact difficulties associated with moves.
In addition, the survey is mainly collected in the census areas that are part of the master sample: this covers almost all urban areas but only part of the rural areas.
Data compilation
The data are adjusted by constructing weights in three steps :
-
correction for non-response
-
weight sharing
-
calibration on margins from the EAR
Sample size
The initial sample consisted of 48,600 address records (AR). More than 2,000 (AR) were added to fill a gap in the initial sample corresponding to individuals born in 1979, 1980, 1989 and 1990 who were absent from the sampling frame. The final allocation of the TeO2 survey was 50,730 AR.

This survey led to the publication of a document that describes in detail the elaboration and methodology of the 2nd edition of this survey, which follows the 1st edition that took place in 2008-2009.
This document is structured in 4 parts. The first part presents the context and the setting up of this survey. The second part presents in detail the sampling method and the survey design. The third part describes the conduct and results of the survey. The adjustment is the subject of the fourth part. Finally, the appendices complete this document.
INED has also published a Data Paper describing the design of the survey and the adjustments made.
