Coherence vs Consistency
Coherence: the extent to which differences between statistics can be attributed only to differences between to the true values of the characteristics they estimate

The role of the Statistical Unit – present situation
ESSnet on consistency of concepts and methods of business-related statistics – 2010 project on statistical units:
•Deliverable 1.1: Direction Report (by Norbert Rainer – STAT Austria).•Deliverable 3.1: Identification and evaluation of business statistics regulations inconsistency (by Sarmite Prole and Svetlana Jesilevska - CSB Latvia).•Deliverable 3.2 part 1 and 2: Identification and evaluation of Member States inconsistency (by Monica Consalvi and Danila Filipponi - ISTAT Italy, Joseph Keating - CSO Ireland, Pierrette Schulz and Sylvie Mabile - INSEE France, Sarmite Prole and Svetlana Jesilevska - CSB Latvia, Kerstin Gruber - STAT Austria)
It is well accepted the necessity to overcome the identified limitations and contradictions of the Regulation 696/93 and the need to increase the coherence of the European economic figures and to build consistent statistics.
Must be understood as to avoid the risk of falling back into the same limitations and contradictions
A consistent definition of a Statistical Unit. The route
1. The willingness component
reduction of the “power” (needs) of the individual parts (each NSI, each domain) to guarantee an homogeneous “government of the system”.
2. The semantic component identification of the context, objective and scope
National European/global and/or
Competivenessprofitabilityproductivity
or Physical production
• Different contents of statistical unit definition• Different level and typology of coherence and consistency • Different “degree of rigor” in the application of the
definition for various subpopulations
A consistent definition of a Statistical Unit. The route
3. The syntactic component.
describes how a definition should be built
a) Not permitting the deduction of a contradictions from the different part of the definition
b) Do not use duplication of concepts
c) Do not use generic concepts not well explained
d) Do not use verbs that allow a “free” interpretation
sells in its own will…which will? legal, economic, of ownership?
…can be constituted by one legal unit, a combination of legal units or of parts of legal units……………………………can correspond to a single legal unit…, an enterprise group…, or …part of an enterprise group…….
4. The semiotics component.
Identifies clarifications and specifications for the practical and homogeneous implementation of the definition.
