The Government Statistical Service’s (GSS) subnational data strategy sets out a framework to guide the GSS in producing and disseminating more timely, granular and harmonised subnational statistics that meet user needs.
“Subnational” refers to all data and statistics that are provided for the 12 International Territorial Level 1 (ITL1) areas in the UK, which include Northern Ireland, Scotland, Wales, and the nine English regions, and for lower-level geographies.
The strategy highlights the crucial role of subnational statistics in ensuring citizens, businesses and policymakers can make informed decisions on the economy, the environment and society.
The Office for National Statistics (ONS) recognises the importance of making regional and local statistics easily accessible to monitor our economy, the environment and society at a subnational level.
The ONS was named in the Levelling Up White Paper, published in February 2022, for “making granular data publicly available through a number of tools” and “harnessing data visualisation techniques and building capacity within the ONS to help decision-makers better understand and compare outcomes”.
In response to the GSS subnational data strategy, the ONS is publishing this plan to provide users with an overview of what we will deliver in the next 18 months. This overview will be mapped against the strategy’s three ambitions, which are to:
produce more timely, granular and harmonised subnational statistics
build capability and capacity for subnational statistics and analysis
improve the dissemination of subnational statistics
While this plan covers our current workstreams for new or improved subnational statistics at the time of publication, it will evolve according to new or urgent requirements. We will provide major updates to the workplan approximately 12 months following publication.Nôl i'r tabl cynnwys
Our focus on the production and dissemination of subnational data and statistics is not new to the Office for National Statistics (ONS). We have a long history of working closely with the Devolved Administrations of Northern Ireland, Scotland and Wales, as well as the combined authorities in England. Our work programme has focused on improving and developing subnational and local statistics to provide a solid information base for regional and local decision-making.
In 2021 and 2022 alone, we released several new subnational publications on different topics (including, but not limited to, the ones listed in this section). This extended the range of local and geographically granular statistics available to our users.
We launched our Subnational indicators explorer, which is an interactive tool that you can use to compare UK local authorities across several subnational indicators. This includes a machine-readable data download and an accompanying dataset providing information and metadata on the publicly available data sources disseminated.
Later this year, we will begin publishing Census 2021 outputs and Census 2021 analysis, which will provide a wealth of new insights about our society at local levels, including heath, education and employment.
Producing new economic statistics
We published experimental model-based early estimates of quarterly regional gross value added for the nine English regions, Wales, Scotland and Northern Ireland, building on our collaboration project with the Economic Statistics Centre of Excellence (ESCoE).
We released gross value added (GVA) experimental data at granular levels of geography, including Middle layer Super Output Areas, Intermediate Zones, health board areas and parliamentary constituencies. We made available even more granular GVA data (at Lower layer Super Output Areas, Data Zones and Super Output Areas level) through the Secure Research Service (SRS) and sought feedback from users through a consultation process.
We analysed labour productivity in towns and Travel to Work Areas across the UK, bringing together our granular GVA estimates with our analysis of the industrial make-up of towns and cities in England and Wales.
Looking at trade and investment, we published our first experimental estimates for the value of imports and exports of goods and services for 2019, at International Territory Levels (ITL) 1, 2 and 3, and 16 city regions, including breakdowns by industry, and EU and non-EU.
Similarly, for the first time, we released experimental subnational foreign direct investment positions and earning statistics by partner economy or industry between 2015 and 2019, at ITL1, ITL2 and city region level.
We added new questions to the Foreign Direct Investment (FDI) Survey, which included questions asking for companies to provide subnational information. Our Foreign direct investment, overview of new survey questions, UK: March 2022 progress report covers the type of information received for the 2020 reporting year.
Expanding household and environmental statistics
We expanded our housing affordability series to include new analysis of private rent prices as a percentage of gross monthly household income in England at regional level.
We published analysis on the impact of homeworking on spending, including a focus on the geographic differences in homeworking and spending, in terms of urban versus rural, high streets versus suburbs, and regional variation.
We explored methods to estimate turnover and employment in the low carbon and renewable energy economy (LCREE) for UK countries and English regions.
We brought together a range of indicators on the extent and condition of nature in the UK, including statistics for the four UK countries, in a new structure aligned with the UN system of environmental economic accounting.
Providing detailed health statistics
We published statistics on excess deaths in England and Wales, including deaths due to coronavirus (COVID-19) and due to other causes, broken down by age, sex and local authorities.
We also published an experimental analysis of coronavirus (COVID-19) cases in school pupils aged 4 to 15 years attending state-funded schools, by demographic and geographic characteristics and vaccine status.
We used our experimental Health Index scores for England, available at national, regional, county and local authority level, to publish an article providing insights into England’s health before the coronavirus (COVID-19) pandemic. We also launched an interactive tool that you can use to explore how health changed in your local authority area in England between 2015 and 2019.Nôl i'r tabl cynnwys
In addition to continuing to produce a wide range of statistics and analysis at different geographical levels, the Office for National Statistics (ONS) recognises the need to invest in improving the existing subnational releases, producing new subnational statistics, and enhancing our digital publishing and dissemination tools to reach more users.
This workplan lists the main subnational workstreams planned for the next 18 months across the ONS, providing a short description of expected outputs and indicative timeframe. The workstreams are grouped according to the ambition they meet from the Government Statistical Service’s (GSS) subnational data strategy. This list does not include regular subnational releases, which can be found on the release calendar.
