Thinking about quality when producing statistics

Statistics should be produced to a level of quality that meets users’ needs, and quality assurance (QA) should be proportionate to the nature of the quality issues and the importance of the statistics in serving the public good.

In this guide we provide some questions that analysts producing statistics can use in considering quality at each stage of production. This list is adapted from a series of questions we asked teams during our review of the principles and processes underpinning the quality of HMRC’s official statistics, and draws on QAAD Questions which help producers find out about administrative data.

This quality guide is not a checklist but is designed to be used alongside your own organisation’s guidance, as well as alongside external resources – take a look at the list at the end. GSS guidance on best statistical practice for quality assurance is available on the Policy and Guidance Hub.

OSR Review of approaches to addressing weaknesses in the RPI

In OSR’s Regulatory Work Programme for 2019 to 2020 in respect to the economy theme,  among our priorities for the year is regulatory work on inflation statistics. We cited work arising from any change to the Authority’s approach to the RPI and to the measurement of Owner Occupiers’ Housing Costs within ONS’s CPIH statistics.  Following a request from the RPI/CPI user group that OSR consider the proposed changes to the RPI with respect to the Code of Practice for Statistics, the Chair of the UK Statistics Authority, Sir David Norgrove, wrote to the user group. OSR’s response to the concerns of the user group can be found here in the annex to Sir David Norgrove’s letter. OSR expects to publish the findings from its review of ONS’s recent work on CPIH statistics in March 2020.

Experimental statistics – official statistics in development

About this guidance

This guide sets out the Office for Statistics Regulation’s expectations regarding the production and handling of experimental statistics, a subset of official statistics going through development and evaluation, in line with the Code of Practice for Statistics.

The Code of Practice encourages innovation and improvement and highlights the need for National Statistics and other official statistics to remain relevant for use, to provide a dynamic public service.

Regulatory guidance – Building confidence in the handling and use of data

This guide provides some further insight for statistics producers into the principle T6 Data Governance when handling data to produce and publish official statistics, and when making that data available to external users, in ways that are transparent and accountable (see page 3). It also draws on our findings from a review of the UK statistics system’s ability to provide greater insight to users via linked data: joining up data for better statistics. We have summarised lessons from this review (on pages 4 and 5), to give examples of the actions that producers can take to maximise the potential of data when producing official statistics. They illustrate practices that we look for when assessing compliance with the Code of Practice for Statistics.

UPDATED 22 October 2018: the list of relevant legislation has been extended to include the Statistics of Trade and Employment (Northern Ireland) Order 1988 (page 3).
