1. 2.1 - IESS Framework Regulation update And implementation for SILC

2. - Precision requirements (incl. regional) (Annex II)
IESS
IESS defines:
Domains; topics; detailed topics, e.g.: health; health status … health determinants; smoking – (Art 3 & Annex I)
Statistical populations, sampling frames, units, sources, quality (Art 5, 8, 11, 12 & Annex III)
Specifications of data sets; increase for variables 1st implementation 5%, later changes (over 4 years) detailed topics  5%, variables 10% (Art 5a, 6)
- Periodicities, transmission and deadlines (Art 4, 7, 9, 10 & Annexes IV and V)
- Precision requirements (incl. regional) (Annex II)

3. Main survey characteristics for SILC already defined under IESS
shorter deadlines for data transmissions (December N for survey N, income N-1),
reformulated precision requirements, national and regional (AROPE) + longitudinal (persistent AROP)
data collected with 3 frequencies: yearly (nucleus), every 3 years and 6 years (rolling modules) and on ad hoc basis (new policy needs modules)
duration of the panel: 4 years, 6 years possible

4. Standardised definitions
IESS
For the implementation and details of its elements, IESS plans delegated and implementing acts, either horizontal (for all surveys) or domain/survey specific
Horizontal acts
Delegated:
Multiannual Planning
over 8 years (art 4)
Topics (changes, art 3)
Implementing:
Standardised definitions
& variables ("all domains") (art 6)+ Quality reports (general) (art 12)
For each domain LFS, SILC, HBS, EHIS, AES & ICT but with the same structure:
Delegated acts (art. 5a of IESS) on number & names variables
Implementing acts (art 6, 7 and 12 of IESS)

5. SILC Implementing Regulation
Subjects (detailed) – art 6:
Definitions and characteristics (units, scope, sample, collection)
Characteristics of variables (Nucleus + rolling, new policy needs modules separately)
Tracing rules (longitudinal)
Imputations, substitutions
+ Data transmission – art 7
+ Quality reports details - art 12
Aims:
Simplifying and cleaning/integrating (none since 2003)
Reinforcing quality and comparability
Priority (IESS): timeliness, precision), rolling modules and longitudinal (optional
