National surveys
Survey methodology
Frequency
Regarding transnational surveys, regular periods are given for the EWCS, EU-SILC,
CVTS, and ESS. The 'Labour Force Survey' ad hoc module is a one-off exercise
although the regular European 'Labour Force Survey' to which it is attached
is a
regular
quarterly survey. The 'Working life barometer in the Baltic countries'
will most likely not be repeated. For Estonia, the 'Working Life Barometer'
survey was conducted along similar lines in 2005.
The approximate frequency ranges from annual surveys – in particular
those with a panel design – to repetition in a cycle of 10 years. Most
of the surveys are conducted with a regular frequency and have subsequent
editions within the next two to five years. The German 'Socio-Economic
Panel' (SOEP) has so far run to 22 waves since the first survey in 1984.
A survey with a general focus can include differing specific modules
in each edition and repeat them in fixed or varying cycles. The German
'Socio-Economic Panel' study includes work-related questions in all
waves and has special topical modules. These specific modules are repeated
after some years in an adapted form. Specific modules on working conditions
have been included in 1995, 2001, 2006. Work-related training was a
special topical module in 1989, 1993, 2000, 2004.
