Data description
The LFS questionnaire is structured around the following themes:
-

-
the status of an activity according to the ILO definition;
-
the detailed description of the current main job (occupation, working time, kind of contract, income from work, etc.);
-
the description of previous professional activiy;
-
the level of education and participation in training;
-
the receipt of benefits, including unemployment benefits and old-age pensions;
-
health status;
-
social and geographical origin;
-
labour market trajectory over the past 12 months.
In 2023, the complementary module focuses on pension and labour market participation.

Reference area
France hors Mayotte
ILO labour force status is measured with reference to a given fixed week, known as the "reference week". Each week of the year is a reference week.
Comparability - geographical
The results are comparable to those of European countries complying with the European IESS regulation, which aims to go further in the harmonisation and comparability of data, moving from harmonisation by output (variables) to harmonisation by input (how information is collected).
Comparability - over time and CC2. Length of comparable time series for U
Comparability over time is ensured through the use of stable methods.
In 2021, the renovation of the survey has led to a backcasting of previous results to ensure this comparability.
Source data
In metropolitan France, the sampling frame for the Employment survey is the demographic file of dwellings and individuals (Fideli).
In the DOM, the sampling frame is the population census.
For more details, please refer to the "methodological documentation" section.
Data compilation
- For metropolitan France, a two-steps weighting method is applied to correct for non-reponse and control for sampling fluctuations: calibration and non-response model on variables from the sampling frame in the first step, calibration on external data (population by age, sex and region; number of dwellings) in the second step.
- For DOM, a two-steps weighting method is also applied: non-response model on variables from the sampling frame in the first step, calibration on external data (population by age, sex and region; number of dwellings) in the second step.
Sample size
In 2023, each quarter, 80 000 dwellings are surveyed.
