The value of statistical data is maximised through use of common frameworks, standards and classifications.
Common frameworks, standards and classifications are the essential operating framework of statistics production. They assist in maximising the effectiveness of statistical outputs and the efficiency of the production process. They facilitate the production of statistics to provide a consistent and coherent picture of New Zealand's economy, society and environment, and allow comparisons to be readily made over time and across geographic areas, industries and other domains.
Common methodologies enhance coherence, while the use of statistical standards and classifications permits the repeated collection of comparable data. Coherence is helped by:
- The use of conceptual frameworks provide a basis for consolidating statistical information about certain sectors or dimensions of New Zealand society.
- The use of standard definitions for the subject-matter concepts, variables and classifications used, as well as the populations and statistical units to which they apply.
- Promotion of, and support for, the use of statistical standards and classifications in official statistics produced by other agencies.
Under the Statistics Act 1975, the Government Statistician is required to "define, lay down and promote standard concepts, procedures, definitions and classifications for use in official statistics".
Standards for harmonisation of official statistics will aim to cover:
- frameworks
- data item definitions
- concepts
- statistical units
- coding processes
- derivation procedures
- harmonised questions and question modules
- classifications, eg geographical, social and economic.
