We have corrected errors with the "cardiovascular mortality considered preventable in persons aged under 75" and “adults that currently smoke cigarettes” indicators.

Previously we showed the cardiovascular mortality rate using the 2016 definition of avoidable and preventable mortality. For the smoking indicator we stated district boundaries were as of 2020. We should have shown the cardiovascular mortality rate using the most recent definition as decided in 2019.

For the smoking indicator we should have stated district boundaries were as of 2019 were for England and Wales and as of 2018 for Scotland. This correction affects the accompanying dataset and data download.

This happened because of a human error.

Compare a local authority and the UK average (median) local authority by different indicators, such as weekly pay and healthy life expectancy.

You can also add and compare up to three other local authorities.

Where the chosen local authority is more than one standard deviation away from the median, you will see the indicators highlighted under "better than the median" or "worse than the median". Some indicators have higher values positioned on the left under "worse than the median" such as the percentage of smoking adults because it is more intuitive.

Updates 31 August 2022

Nine new indicators have been included, they are:

  • total value of UK exports
  • inward foreign direct investment (FDI)
  • outward foreign direct investment (FDI)
  • aged 19 years and over further education and skills achievements
  • aged 19 years and over further education and skills participation
  • aged 16 to 64 years level 3 or above qualifications
  • cancer diagnosis at stage 1 and 2
  • cardiovascular mortality considered preventable in persons aged under 75
  • homicide

We expanded the range of geographies included in the accompanying dataset and the data download, for example adding data for city regions, international territorial levels (ITLs), English regions, countries, Great Britain and UK, where available and methodologically comparable. For more details see column R, data dictionary tab, in the accompanying dataset.

Two indicators, employment rate for 16 to 64 year olds and aged 16 to 64 years level 3 or above qualifications, are based on re-weighted Annual Population Survey datasets updated on 16 August 2022. Read more about the Impact of reweighting on Labour Force Survey key indicators.

The indicators confidence intervals have been included in the accompanying file where applicable and available, stating level of confidence.

Notes

This interactive tool will be updated on a quarterly basis. The data displayed will not always match the most recent version of the related data source where new data become available in-between updates. Please refer to the data dictionary in the accompanying dataset for details on years covered and geographical coverage of each indicator, and for links to the original data sources.

This third iteration of our interactive tool shows 27 subnational indicators. Data for nine more indicators are available in the accompanying dataset and in the data download. These are:

  • total value of UK exports
  • inward foreign direct investment (FDI)
  • outward foreign direct investment (FDI)
  • 4G coverage
  • aged 19 years and over further education and skills achievements
  • apprenticeship starts
  • apprenticeship completions
  • new houses
  • homicide

The polarity of the indicator determines whether the lowest or highest value is positioned on the left-hand side of the jitter plot. The jitter plot presents the indicators so that "worse than the median" are on the left, and "better than the median" are on the right regardless of the value itself (for example, a high percentage of smoking adults is presented on the left-hand side). The indicators for which higher values are shown on the left are:

  • public transport or walk to employment centre with 500 to 4,999 jobs
  • cycle to employment centre with 500 to 4,999 jobs
  • drive to employment centre with 500 to 4,999 jobs
  • cigarette smokers
  • overweight children at reception age
  • overweight adults
  • cardiovascular mortality considered preventable in persons aged under 75
  • anxiety

Because of methodological differences, data for 18 indicators (four of which not displayed) are included for England only, one indicator (not displayed) is included for England and Wales, and four indicators are included for Great Britain, rather than for the whole of the UK. We are continuing to work with colleagues in the devolved administrations to improve the comparability of indicators at UK level where possible, while acknowledging the devolved nature of some policy areas.

Employment rate for 16 to 64 year olds data have been updated to 2021 for Great Britain. To ensure comparability, data for Council Areas in Northern Ireland have been omitted from this iteration, as not yet available for 2021. Please refer to the NISRA website for 2020 employment rate data for Northern Ireland.

The presented personal well-being estimates, sourced from the Annual Population Survey datasets year ending March 2020 to year ending June 2021, are affected by an error in the calculation of population weights. This error led to a slight overestimation of the non-UK population by approximately 0.5%. This represents less than half the size of the sampling variability. We aim to explore the extent of this error on personal well-being estimates and revise them as necessary for the next publication of the annual personal well-being in Autumn 2022.

Our interactive tool is built on 2021 lower tier local authorities (local authority districts and unitary authorities). Where the underlying data are not available for 2021 boundaries, data points for local authorities that recently underwent changes will not appear in the interactive tool but will be available in the accompanying dataset and in the data download.

Data for eight indicators are only published for upper tier local authorities (counties and unitary authorities) and not for lower tier local authorities (local authority districts and unitary authorities). For example, 20 indicators will appear in the interactive tool for Fareham, however, the other seven will be available for Hampshire in the accompanying dataset and in the data download. These are:

  • female healthy life expectancy
  • male healthy life expectancy
  • early years communication
  • early years literacy
  • early years maths
  • pupils at expected standards by end of primary school
  • schools and nurseries rated good or outstanding

In line with the original data sources, data for Isles of Scilly and City of London are not available for several indicators. Please refer to the original data sources to learn more about the reasons for excluding them.

About this tool

The Subnational indicators explorer, the first step towards an Explore Subnational Statistics service, promotes transparency and makes it easy for users to access and visualise subnational indicators in one place.

The indicators are grouped in three categories ("boosting productivity, pay, jobs and living standards", "spreading opportunity and improving public services" and “restoring a sense of community, local pride and belonging”) in line with the Levelling Up the United Kingdom: missions and metrics Technical Annex.

Methodology

To position each local authority within the cloud of local authorities, we used a robust measure of statistical dispersion called the median absolute deviation (MAD). We preferred the MAD to the mean absolute deviation as outliers have a smaller effect on the median than they do on the mean.

To compute the MAD for a specific indicator, first calculate the median of all values at local authority level for that indicator. Second, subtract the median from each value and get the absolute values. Finally, calculate the median of the median absolute deviations obtained from the previous step and multiply this by 1.4826. This constant is linked to the assumption of normality of the data.

The distance of each local authority from the centre line (the local authority with the median value in the distribution) is equivalent to the difference between the value of the chosen local authority and the value of the median local authority, divided by the MAD. We consider the resulting score to be positive or negative if the score is at least one MAD above or below the median. Usually, a score is considered to be significantly different from the median score if it is at least two MADs above or below the median.

Where the score of a local authority is more than 7.5 MADs above or below the score of the median local authority, the local authority is shown at the end of the scale and its position is not fully representative of its score.
