Chapter 6
• Provisional text for the chapter, based on
similar text approved by the Statistical
Commission for other areas of economic
statistics
Structure of the chapter
A. Introduction
B. Statistical units
C. Classification of units by kind of economic
activity
D. Characteristics of statistical units
E. Data items
B. Statistical units
• A statistical unit is an entity about which
information is sought and for which statistics
are ultimately compiled
• Other units are also distinguished (i.e.
reporting and collection units), but the stat.
units are of primary interest
• Basis of statistical aggregates
• Data items applies to all units
Selected statistical units

Enterprise
Enterprise group
Establishment
Kind-of-activity unit
Unit of homogeneous production
Households
• IRIS and ISIC Rev. 4 are recommended references for
the definitions and discussion of statistical units
• In general, it is recommended that large enterprises
engaged in many economic activities that belong to
different industries be broken into one or more
establishments, provided that smaller and more
homogeneous units can be identified for which data on
energy production or other activities attributed to
energy sector may be meaningfully compiled
C. Classification of stat. units by
kind of activity
Statistical unit can engage in a number of
activities.
Activities are classified into principal, secondary
and ancillary activities.

D. Characteristics of stats. units
They are data items used for their unique identification,
classification within particular activity area of energy,
for description of various aspects of their structure,
operation and relationship with other units.
Important for
effective organization of the statistical sample surveys
comparisons between data from different data sources

Recommendations
Countries are encouraged to use the
establishment as a statistical unit for energy
statistics
Countries are encouraged to collect data for
all relevant establishments belonging to a
multi-establishment enterprise within a
country
E. Data items
Reference list for use in energy statistics
It is recommended that countries select from that list the
data items which are relevant for their national
programmes of energy statistics in accordance with
their own statistical circumstances, respondent load
and available resources.
It is further recommended that, while developing their
own national lists of data items, countries consistently
use the definitions of products and flows presented in
chapters 3 and 5.
Organization of data items
They are organized according to the following
main categories of energy products
This reflect common practices at national and
international level (e.g. UN Manual F.56, IEA
structure of questionnaires, EU regulation of
energy statistics)
Within each category of products
a) characteristics of stat. units
b) data items for the energy sector
c) data items for the consumption sector
Data items mainly in physical units but some also
in monetary units
Data items for oil and oil products
List of products for which the list applies
Characteristics of stat. units
Employment (e.g. Tot. number of persons
employed)
Data items for the energy sector in physical units
(production, imports, exports, etc.)
Data items for the energy sector in monetary units
(output, imports, exports, inventories etc.)
Infrastructure (refinery capacity, investments)
Data items for oil and oil products
Data items for the consumption sector in physical
units (imports, exports, use of energy products
for non-energy use, use of energy products for
final energy consumption, stocks, etc.)
Data items for the consumption sector in
monetary units (value added, cost of energy
products purchased for non-energy, etc.)

stat. units
