Harmonisation is about making statistics more comparable, consistent and coherent. It improves efficiency and enables users to draw more value from statistics. To improve harmonisation, analysts, researchers and data owners should aim to, where appropriate:
- use consistent definitions and survey questions in data collection
- improve understanding of how data and statistics can be integrated and used in combination
- present statistics in a comparable and coherent way
But, since statistics producers will each have their own specific user requirements, this is not always appropriate. In these cases, they should consider other actions to improve the coherence of their data and statistics, such as providing improved guidance.
What support is available?
Harmonised principles are guidance on how to make statistics more comparable by encouraging producers to use the same methods of data collection and presentation. The principles include definitions, survey questions, standards for administrative data, rules for presentation and guidance for users.
Producers of statistics can use harmonised principles to improve harmonisation when they collect and publish statistics on a given topic.
Users can use the principles to improve their understanding of how to compare and combine statistics when appropriate.
We have produced A beginners guide to harmonisation (108KB).
This guide will provide answers to our frequently asked questions and give an overview of harmonisation and what the GSS harmonisation team do.
If a department needs help with harmonisation, the harmonisation team (based in the Office for National Statistics but here to help the whole Government Statistical Service) are happy to collaborate closely.
Email firstname.lastname@example.org to find out more.
We have developed a two year GSS Harmonisation Strategy.
This strategy sets direction on the coherence and comparability of statistics across the GSS. It was developed through consultation with key stakeholders across the GSS and sets out realistic actions to improve comparability and coherence across official statistics. The strategy will provide guidance for all those involved in delivering statistics across the GSS.
Harmonisation champions work across the GSS to increase awareness of harmonisation and the help available.
