20-21 september 2012
1. Background
Impact of census results on:
Revision of population estimates
Weights used in surveys such as EU LFS and EU SILC.
First discussion in the DSS meeting of 21 March 2012
General agreement on a coordinated approach for population estimates and on a set of key principles for LFS and SILC surveys.
Bilateral contacts to take place with some countries
Further discussions at technical level
New discussion in September DSS meeting
Input from Migration, LAMAS and Living Conditions WGs

4. 2. Population estimates: a coordinated approach
20-21 September 2012
2. Population estimates: a coordinated approach
If revision needed, it should cover the whole intercensal period
(2) Revised data uploaded on Eurostat website as soon as they are transmitted by a Member State
(3) EU and Euro Area aggregates for past years systematically revised after each transmission of revised annual data from a Member State

5. 2. Population estimates: a coordinated approach
20-21 September 2012
2. Population estimates: a coordinated approach
(4) Revised population figures at national level broken down by:
sex and single year of age to be transmitted by 15 September 2013
sex, age and citizenship or country of birth to be transmitted by end of December 2013
(5) Revised population estimates at regional level to be transmitted by 15 December 2014

Group 1: No need to implement revision
BE, DK, FR, NL, SI, FI, SE, IS, NO, CH, MK
Group 2: Bilateral discussions needed for the following reasons:
No revision planned/not decided yet but need for revision to be thoroughly discussed
DE (internal plan)
No revision planned for citizenship or country of birth but consistency with other population data to be discussed MT
Revision planned for shorter time series than requested
BG, CZ, HU, PL, SK

8. 3. EU LFS and EU SILC: agreed principles
20-21 Setember 2012
3. EU LFS and EU SILC: agreed principles
Revision
Justification by countries not sending revised weights that the impact of the new Census on estimates is null or negligible (smaller than the precision used for publication of the headline indicators)
Length of the time series to be reweighted backwards: flexibility but a minimum reconstruction of back series to be ensured (to avoid breaks in the time series for the Europe 2020 headline indicators) in time for the mid- term review of EU-2020
LFS: at least from 2010
SILC: at least from 2008

9. 3. EU LFS and EU SILC: agreed principles
20-21 September 2012
3. EU LFS and EU SILC: agreed principles
(3) Given high workload, bilateral discussions on the timing required for countries wishing to go beyond the minimum length of reweighted time series
(4) New data to be transmitted as soon as they are ready helps spreading the workload for Eurostat
(5) Publication by Eurostat of the re-weighted series after transmission and validation.
