The Labour Force Survey has undergone considerable reform in 2017. From 2017 onward, we work with a rotating panel, we use different data collection methods, and the weighting method was substantially reviewed. This led to a break in our results. Consequently, the figures obtained with the old method cannot be compared to those obtained with the new method.

Labour force survey (LFS)

Purpose and short description

The Labour Force Survey (LFS) is a socio-economic household survey. Its main objective is to classify the working age populatioin (15 and older) into three groups (persons employed, unemployed and inactive persons) and to provide descriptive and explanatory data on every category. This survey is also carried out in the other EU Member States and is coordinated by Eurostat, the statistical office of the European Union. In Belgium, the LFS is organised by the Directorate-General Statistics of the FPS Economy. The objective is to obtain comparable information at European level, in particular as regards employment and unemployment rates as defined by the International Labour Office (ILO), but also to collect and disseminate data that are otherwise not available, for example about the mobility of workers, the reasons for working part-time, the various forms of part-time employment, the profession, the educational level of the working age population,...

Survey population

Members of private households aged 15 or older.

Sample frame

Demographic data from the National Register.

Data collection method and sample size

Data are collected through face-to-face interviews. Since 2017, there have been three (shorter) follow-up surveys to which households respond online or by telephone.

Households with only inactive persons older than 64 can also be interviewed by telephone.

Every year, around 47,000 households receive a letter asking them to take part in this survey.

Response rate

The response rate is above 75 %.



Release calendar

Results availability: around 3 months after the end of the reference period.


Employed population (ILO): The employed persons are persons aged 15 or older who during the reference week performed work during at least one hour for wage or salary or for profit; or those who had a job but who were temporarily not at work during the reference period. The family workers are also included. The employed persons are divided into three groups according to their professional situation:

Paid employment: All persons aged 15 or older who, during the reference week, performed work during at least one hour for wage or salary in cash or in kind (with or without formal contract), or who were temporarily not at work (due to sickness, maternity leave, holidays, social conflicts, bad weather or for other reasons) and had a formal attachment to their job.

Self-employment: All persons who do not work for an employer and who performed work during at least one hour for profit during the reference week or were temporarily not at work. This category comprises self-employed workers (with no staff), employers (with staff) and unpaid helpers.
