There are many audiences
Do not for get the basics
Emphasise the basics
Output tables are not usually good
for data collection
• Allow for change
Audiences for information:
from data to indicators
Headline indicators
Data users
Indicators on
specific subjects
or industries
Decision makers & wider public
Indicators
Managers
and analysts
Researchers
Environmental
Accounts and other
aggregations
Data items
Information
Audiences
• The audiences vary in terms of
background
– Compilers in statistics offices as well
as other agencies
– Mandate and institutional
arrangements of compilers
– Level of experience of individuals
doing collection
– History and sophistication of agency
Basic statistical process are
important and must be emphasised
Dimensions of data quality*:
Relevance – does the data answer the questions?
Accuracy – how closely does the data represent the real word?
Timeliness – is that data available in time for decision making?
Accessibility – how are the data accessed?
Interpretability – can the data be easily interpreted and used?
Coherence – how does the data relate to other data?

Important issues to
emphasise for new compilers
• Institutional arrangements
• Process of development
– (Including identifying and
acknowledging existing data providers
and identifying key questions not
currently addressed by data)
• Importance of data collection
strategy
• Key data collection considerations
– Frame creation and maintainance
– Design of collection instrument
– Data collection is on-going

Output tables are not usually
suitable for data collection
Australian experience with business
surveys
• Good form design is essential (see
Dillman)
• Use language and concepts familiar
to those expected to complete form
– Do not expect them to understand the
concepts required to complete energy
balances or energy accounts
Diagrams can be helpful
• In explain concepts in manuals and
could be useful in data collection
and presentation

capacity
Lesson 6 – Integration of
biodiversity data with
other data is critical
Lesson 7 – Determining
what to measure and how

Lesson 8 – Deciding how
much is enough for
effective monitoring
Lesson 9 – Ability to

Need to be able to innovate and
have access to improved
methods
• A hard copy publication is not the end of the
process
• A knowledge base for recording country
practices
• A forum for on-going interaction of technical
experts
