Surveys, Sources – Swiss Labour Force Survey (SLFS)Overview

Brief description Conducted for the first time in 1991, the Swiss Labour Force Survey (SLFS) is sent out to households every year. The main purpose of the SLFS is to provide information on the structure of the labour force and employment behaviour patterns. Strict adherence to international definitions allows Swiss data to be compared with OECD and EU data. From 2010, the SLFS will be conducted on a continuous basis. The interviews from the 3rd and 4th quarters of 2009 enable the passage from the old to the new SLFS.
