4. The subjects

5. The focus
The 9th workshop on LFS methodology was the first of the 3rd cycle of workshops, covering the years
It was dedicated to survey design, sampling and estimation
It represented the occasion to discuss some issues related to the ongoing renewing of the LFS, beyond the official venue of LAMAS meetings
Even if the subjects were sometimes a bit “technical” the discussion didn’t miss
Some participants came from the methodological units, some other from LFS units, in some cases both came

6. The agenda
A-B: Embedding the LFS in an integrated modular social survey design
The LFS review in the context of the Eurostat programme for modernising social surveys
Anne Clemenceau
Eurostat
From LF Survey to a system of LF Statistics
Johan van der Valk
CBS
Towards an integrated system of household surveys – Implications for the LFS
Jörg Enderer and Thomas Körner
DESTATIS
Distribution of sample in surveys of Central Statistical Bureau of Latvia
Andris Fisenko
Central Statistical Bureau of Latvia
Discussion
Process of modernization of social statistics
Possible integration of the results from different social surveys through statistical matching, need for methodological studies in the modularization framework (as for weighting for instance), concerns about the time schedule for the legal framework, modes, integration of sample units, consistency between submodules and core

7. The agenda C: Sampling design Discussion
How uniform allocation among reference weeks is ensured in the French LFS ?
Sylvie Le Minez
INSEE
Deployment in space and time with relation to monthly processing in the Czech Republic
Ondřej Nývlt, Ilona Nováková
Czech Statistical Office
The Italian LFS sampling design: recent and future developments
Loredana Di Consiglio, Silvia Loriga, Alessandro Martini, Rita Ranaldi
ISTAT
LFS Sample Design, Allocation, Weighting
Gökhan Kocturk
TURKSTAT
Discussion
Pros and cons of the rotational patterns of the sample, how census information should be used for updating the sample design and how to implement these changes and the effect they can produce in the series of estimates, uniform distribution of the theoretical sample along the weeks of a quarter and the deviations that occur in practice

8. The agenda D: Multiple mode designs Discussion
Development and Implementation of a Mixed-Mode Multipurpose Survey Tool for Official Statistics
Marc Plate
Statistics Austria
Using multiple mode designs
Liisa Larja, Pertti Taskinen
Statistics Finland
Redesign of the Dutch LFS, from CAPI to CAWI/CAPI/CATI
Martijn Souren
CBS
Discussion
The challenges of IT implementation, the assessment of mode specific measurement effects, the cost savings that might be obtained through the introduction of multiple mode designs
This session was in close connection to the ongoing ESSnet project on Data Collection for Social Surveys using Multiple Modes. The final workshop of the ESSnet project on 4-5 September 2014 in Wiesbaden will provide the opportunity discuss the topics of the session in more detail

9. The agenda E: Effective data collection designs and subsampling
Arturo de la Fuente
Eurostat
Comparing Subsample Approaches
Ole Villund
Statistics Norway
Structural variables: Weighting the annual subsample
Carlos Pérez-Arriero
INE
Collecting the household data as a sub-sample – comparing the weighting model in the Danish household survey to the weighting model of the core-LFS
Jonas Kylov Gielfeldt
Statistics Denmark
Discussion
A picture of the data collection strategies adopted by NSIs as for subsampling and rotation scheme to conclude that we’re far from harmonization, exploring statistical matching or data linking inside the LFS, the need to study methodological issues related to subsampling (weighting for instance), individuals vs households, how to use available auxiliary information in calibration

10. The agenda F: Estimation and consistency issues Discussion
Estimation in the Swedish LFS – an example of combining survey data from independent samples
Martin Axelson, Frida Videll
Statistics Sweden
Main issues of the weighting procedure in the French LFS
Fabien Guggemos et al.
INSEE
Consistent weighting of the Dutch LFS; Monthly, Quarterly, Annual and longitudinal data.
Hendrika Lautenbach and Martijn Souren
CBS
The IT-LFS consistency framework
Antonio Discenza, Silvia Loriga, Alessandro Martini
ISTAT
Discussion
Differences in the weighting schemes, differences in auxiliary information used in calibration, consistency is needed? How to reach consistency, how to explain inconsistency to the users

11. The agenda
G: Estimation exploiting the longitudinal dimension of the LFS
Longitudinal Weights for the Production of Transitions and Flow Estimates
Katrin Baumgartner, Alexander Kowarik, Angelika Meraner
Statistics Austria
An example of longitudinal LFS weights
Katja Rutar
Statistical Office of the Republic of Slovenia
Regression composite estimation for the Finnish LFS from a practical perspective
Riku Salonen
Statistics Finland
Discussion
Interesting topic, because of the new requirement into the legal basis about the overlapping of the sample, the new studies about the production of flows by Eurostat using a common method, the possible use of longitudinal information in estimation through regression composite estimator.
