The 2008 SNA
implementation strategy
• The ways of implementing the system
vary greatly and depend on the general
strategy adopted for the statistical
system.
• The SNA implementation strategy is
part of the overall strategy of the
statistical system

Phase D
Phase A: Aims and
objectives
The decision on whether to implement the
SNA is based on:
– Availability of data sources supporting
its implementation.
- Institutional capacity of the unit in charge
of implementing the SNA;
– Needs of national and international
users for national accounts indicators
Phase A: Aims and objectives
(cont)
The targets can refer to the six
‘milestones’ adopted by the UN Statistical
Commission and the MRDS
Guidelines
ISWGNA developed a set of six milestones to
assess the scope of accounts that are
compiled by countries. These milestones
were later supplemented by three data sets
describing
(a) minimum set of accounts that need to be
compiled;
(b) a recommended set of accounts;
(c) and a desired set of accounts.

production approaches, by industry;
The main results are:
– GDP in current and constant prices by
production and expenditure side
– P, IC and GVA by industry.
Corresponds to milestone 1 and allows the
country to meet part of the MRDS (Tables
101, 102, 201, 202)

e. SUTs and production and generation of income
account by institutional sector;
f. Full sequence of accounts for institutional
sectors; estimating accounts for the rest of the
world;
g. Financial accounts for institutional sectors;
h. Balance sheets
Phase A: Aims and objectives
(cont)
Factors for deciding objectives:
- statistical capacity for providing the data sources
for NA;
- the human resources (number and level of
knowledge)
- possibility to use administrative data
- structure of the economy, especially the extent
of the informal sector and the ability of data
sources.
• Generally, implementation of SNA starts with the
compilation of GDP by production and
expenditure approaches
Phase B: Organization
1. Institutional context
2. Organizational aspect
- NA Department
- Human resources
- Data collection
Phase B: Organization
1.Institutional context
Institution in charge of implementing and
developing national accounts.
• In a large percentage of countries, the
national accounts are the
responsibility of the national
statistical office.
Phase B: Organization2. Organizational aspect
Conditions for SNA implementation refers to:
- organization of the NAD
- mobilizing and developing human
resources
- cooperation within the statistical office
- cooperation with other administrative
institutions
- tasks for NA compilation (for example
government accounts by the MoF )
Phase B: OrganizationNAD
Implementation of national accounts requires:
- Existence of basic conditions: SBR and
classifications
- Main statistics: economic statistics, household
statistics, prices, etc.;
- Coordination and cooperation between different
departments in NSI
- Cooperation with other administrative institutions
in order to access the data required for
compiling national accounts.
Phase B: OrganizationNAD
(cont)
Typical tasks of a NAD are:
- Collecting statistical and administrative data
sources;
- Translating the statistical and administrative
data sources into concepts of national
accounts.
- Elaborating national accounts indicators;
- Preparing publications and other documents
for the dissemination of national accounts;
- Making proposals and taking actions to
improve data sources and compilation

Profile:
- A university education, wherever possible, in economics or
statistics;
- Work experience in different economic domains;
- Ability to understand and apply the SNA methodology;
- Good knowledge of economic legislation and economic
phenomena in the country;
- Good knowledge of the economic and social indicators existing
in the statistical and administrative system.
To obtain this high level of professional capability the staff
- Should be permanently trained
- Should be supported by the institution management
Phase B: OrganizationHuman resources
( cont)
Professional independence of national accountants for :
- the definition of the system and its adaptation to the countr
- the methods used for estimating national accounts;
- the access to information, especially when it is protected
(fiscal sources, defence information, etc.);
- treatment and measurement of ‘special’ aspects of the
economy, such as illegal activity (illegal labor, drug
production, etc.) that are in fact the weak points of political
power;
- responsibility for the main indicators, such as GDP,
economic growth rate or revenue distribution, especially
when the values are different from government forecasts or
expectations
Phase B: OrganizationData collection
The next step is to establish formal
relationships for ensuring availability of
the data for compiling national
accounts.
- Internal cooperation : industrial statistics,
foreign trade, agriculture,
demographics, education, health,
prices, etc
- External cooperation; administrative
data
Phase B: OrganizationData collection
(cont)
Access to data:
- agreements, protocols or memorandums
Content:
- The data to be delivered;
- The level of detail of the data (individual,
aggregated, by region, etc.)
- The frequency (monthly, yearly, etc.);
- The data collection method (access to data
base, electronic format, paper, etc.).
Phase B: OrganizationData collection (cont)- Protocol
• Legal framework: law / regulation on the organization and
functioning of the each institution party in the protocol
<Institution1> and <Institution2> agreed following:
- The objective of the Protocol: main goal of the protocol
- Duration Protocol
- Obligations of partis: change of data, confidentiality
- Notifications/Communication: Mentioned type of
communication (written, by telephone, fax, email)
- Annexes
• description and structure of data files which are changed
between parteners
• working group responsabilities
• nomenclatures
• type of transmission, type of file, name of file
• description of the File Structure
• deadline for transmission
Phase C: Compilation
The main phases are:
- Designing the central framework;
- Identifying data sources;
- Collecting data;
- Translating data into national accounts
concepts;
- Elaborating estimates;
- Data revision.

Phase C: Compilation
Designing the central
framework
The determination of the four
classifications used in the system:
- Product detail;
- Economic activities;
- Transactions, other flows and stocks;
- Sectorization of the economy
Phase C: Compilation
Identifying data sources
1. Statistical data sources (statistics on
producer sales and production costs, on
investment, on employment, wages and
salaries, on household expenditures, on
consumer prices, on producer prices and
interest rates, on imports and exports, etc)
2. Administrative sources (government
revenue and expenditure, financial
statements of non-financial and financial
units, balance of payments, etc.).
Phase C: Compilation
Identifying data sources
(cont)
Lack of data
Options:
- to carry out a rough estimate of NA
using poor data sources and indirect
information,
- to stop implementation of SNA
implementation and development until
the necessary data sources become
available.
Phase C: Compilation
Identifying data sources (cont)
Actions:
a. Start estimating GDP even if the lack of
information may affect the quality of the initial
results
b. Ensure at the same time that the necessary data
sources are developed. Propose and promote:
– Improvement of the existing statistical data
sources
– Implementation of new statistical surveys that will
provide the missing information;
– Development of collaboration with administrative
institutions to improve or develop their data
sources.
Phase C: Compilation
Collecting data
Main activities:
- Agreements on data delivery: what data will be
delivered, in what detail and with what frequency,
when and in what format, etc.;
- Checks on the data delivered: timeliness, detail and
completeness;
- Data storage in automated systems (spreadsheets
or databases) for compiling national accounts;
- Searches for other relevant quantitative and
qualitative information, e.g. by reading specialized
journals, newspaper articles and annual reports of
various large companies, organizations,
foundations, or by asking corporations, institutions
and experts directly.
Phase C: Compilation
Collecting data (cont)
Steps for the collection of data:
- Decide what data is to be used for
compiling national accounts;
- Decide the level of detail of this data;
- Decide how the data will be delivered to the
national accounts department: on paper, in
electronic format (CD-ROM, by email, etc.)
or direct access to the databases of other
departments;
- Establish the deadline for receiving data.national accountants dissemination
calendar (some data before being
published.
Phase C: Compilation
Translating data into the NA
concepts
Translating statistical and administrative
concepts to national accounts concepts
is to be performed by national
accountants themselves.
Use a system of bridge tables at macroeconomic levels, and specific
adjustments called the intermediate
system.
Phase C: Compilation
Elaborating estimates
Activities:
• Checking data sources, with respect to:
- evolution over time;
- coverage
- plausibility of values and volumes;
- conceptual differences with NA concept
• First estimates of national accounts indicators.
• Second estimate -inclusion of additional or more
complete data
• Balancing procedures and reconciling data to
identify data deficiencies and ensure consistency of
results.
• Final estimates
Phase C: Compilation
Data revision
Important revisions:
1. Routine revisions (or current revisions)
2. Benchmark revisions (or major regular
revisions
3.Methodological revisions (or major
occasional revisions)
Phase C: Compilation
Data revision- example
• T + 70 days: first complete GDP
estimate and main national accounts
aggregates on the basis of quarterly
accounts;
• T + 9 months: first complete annual
accounts estimate of GDP and main
national accounts aggregates;
Phase C: Compilation
Data revision- example
• T + 21 months: first revision of annual
accounts estimate of GDP and main
national accounts aggregates;
• T + 33 months: final revision of annual
accounts estimate of GDP and main
national accounts aggregates
Phase C: Compilation
Data revision- example
Three methodological revisions conducted in Slovenia:
• delimitation of market and non-market units together with
improvement of institutional sectorisation,
• introduction of new methodology for estimation of housing
services of owner-occupiers,
• estimation the consumption of fixed capital (including for public
roads, bridges, etc.) by the perpetual inventory method for the
general government sector,
• improvements of GDP exhaustiveness adjustments and other
improvements of methods
• the change in the bookkeeping of financial intermediation
services indirectly measured (FISIM), which were allocated to
the final users of these services.
• measurement of volume changes at constant previous year
prices was introduced.
The results of this methodological revision were published for the
whole 1995-2004 period.
