1
The statistical units model and integration Less is more
Wim KloekSession 32
Q2010 Helsinki, 4 to 6 May 2010
4
The system of statistical units
Backbone of the system of business statistics
Defines the relations between the parts Defines the breakdowns and aggregations Basis for data collection, for data processing
and for dissemination; embedded in the business register and in data warehouses
5
Data integration
Over statistical domains (generating new output)
Over countries (comparability and adding to EU totals)
Results in: higher efficiency, better quality and more output
7
Statistical units production process, 1997
Structural business statistics Enterprise
Short term indicators KAU
Labour cost statistics Local Unit
Structural labour statistics Local Unit
Supply and use tables LKAU
Symmetric input/output tables UHP
8
Current situation
More stovepipe regulations Incomplete implementation of the statistical
units regulation Considerable room for national
interpretations (especially on the criterion autonomy)
9
Proposed solution
Reduce the number of statistical units Stick to the actors approach Clarify the operational definitions
10
Reduce the number of statistical units
Directly improves the potential integration over statistical domains
Simplifies the explanation of remaining differences
Harmonises national business registers and data warehouses
Courageous proposal: three units
11
Actors approach
Meaningful analysis of macro data in meso and micro data
What is the actor depends on the variable concerned
Reduce to the core economic variables (describing the production process and describing financial processes)
The actor in the production of value added (‘the enterprise’) should be used in other domains
12
Clarify the operational definitions
The actual delineation of statistical units involves an integrated decision on several relations at the same time:
What is the actor for financial processes? What the actor(s) for production processes? What is the link to legal units? What is the link to locations?
Autonomy: operational criteria
Link to legal units:different over countries
13
The local unit
Not an actor, but a location Useful for the description of the local labour
market or the local service level Lower threshold difficult to define, both in
theory and in practice The find a location for all economic activities
becomes more dubious
14
The EuroGroups Register (EGR)
Common register of large multinational enterprises provide a shared and coordinated basis for the production of statistics: process integration
Efficient (one time profiling) Improved comparability: same units and
classifications Further harmonisation of national profiling
