Peer review and governance
It's important that our methodology is fit for purpose and robust so that census outputs are:
- high quality
- of public value
We have 3 layers of review and governance to help us make sure our methodology is sound.
Internal peer review
Our internal peer review group is made up of 15 statisticians from National Records of Scotland.
They review and provide feedback on proposed methodologies for each step of census processing. The group meets regularly and provides support to the teams who are designing the methodology for each step in the data journey.
We asked a group of external experts to form an external methodology assurance panel to review our proposed methodologies. The panel meets regularly and have peer-reviewed a different part of the proposed methodology at each session.
After each panel session, they compile a report, providing feedback on whether the methodology is fit for purpose.
The external experts are:
- Katherine Keenan - University of St. Andrews (chair)
- Chris Martin - Ipsos Mori (Deputy chair)
- Genevieve Cezard - Centre for Population Change
- Lisa Rutherford - ScotCen
- Lee Williamson - Scottish Longitudinal Survey
- Federico Andreis
- Alan Marshall - University of Edinburgh (former chair)
The final stage of governance is National Records of Scotland's census design authority. This board is responsible for the overall census design. This is also where all aspects of our methodology are approved. The board uses the advice from the internal and external reviews to make their decision.
External panel meetings and papers
We publish methodology papers and summary reports as soon as possible following panel sessions.
Before we publish, we will:
• work through the advice provided by peer review groups
• update methodology as needed
• complete the internal governance steps towards final approval of the statistical methods discussed in each paper
