In the 2022/23 financial year, various measures of inequality in the United Kingdom decreased when compared with 2021/22. The S80/20 ratio fell from 6.3 to 5.5, the P90/10 ratio from 4.5 to 4.2, and the Palma ratio between 1.5 and 1.3.

In 2023, the United Kingdom's Gini coefficient score was 33.1, a slight decrease when compared with the previous year. The Gini coefficient is a measurement of inequality within economies, a lower score indicates more equality while a higher score implies more inequality.

The overall wealth of households in the United Kingdom was 13.5 trillion British pounds in the period between 2020 and 2022. Of this overall wealth, the top ten percent of households had over 5.5 trillion pounds of wealth, compared with 13.9 billion owned by the lowest wealth decile.

Average UK household incomes taxes and benefits by household type, tenure status, household characteristics and long-term trends in income inequality.

At the turn of the twentieth century, the wealthiest one percent of people in the United Kingdom controlled 71 percent of net personal wealth, while the top ten percent controlled 93 percent. The share of wealth controlled by the rich in the United Kingdom fell throughout the twentieth century, and by 1990 the richest one percent controlled 16 percent of wealth, and the richest ten percent just over half of it.

Three datasets, all carried out by YouGov and the WEALTHPOL team, are included. The first was conducted in Summer 2021, the second in Summer 2022, and the third in October 2022. CSVs, codebooks, and data construction files are included (note the latter include references to other files but show the coding).

What does the data show?

The data shows the S80/S20 income quintile ratio from the UK Climate Resilience Programme UK-SSPs project. The data is available for each ONS NUTS3 shape simplified to a 10m resolution.

The S80/S20 ratio is a measure of the inequality of income distribution. The ratio is the total income received by the 20% of the population with the highest income (the top quintile) against the total income received by the 20% of the population with the lowest income (the bottom quintile).

The data is available for the end of each decade. This dataset contains SSP1, SSP2, SSP3, SSP4 and SSP5. For more information see the table below.

What are the naming conventions and how do I explore the data?

This data contains a field for the year at the end of each decade. A separate field for 'Scenario' allows the data to be filtered, e.g. by scenario 'SSP3'.

What are Shared Socioeconomic Pathways (SSPs)?

The global SSPs, used in Intergovernmental Panel on Climate Change (IPCC) assessments, are five different storylines of future socioeconomic circumstances, explaining how the global economy and society might evolve over the next 80 years. Crucially, the global SSPs are independent of climate change and climate change policy, i.e. they do not consider the potential impact climate change has on societal and economic choices.

Instead, they are designed to be coupled with a set of future climate scenarios, the Representative Concentration Pathways or ‘RCPs’. When combined together within climate research (in any number of ways), the SSPs and RCPs can tell us how feasible it would be to achieve different levels of climate change mitigation, and what challenges to climate change mitigation and adaptation might exist.

Until recently, UK-specific versions of the global SSPs were not available to combine with the RCP-based climate projections. The aim of the UK-SSPs project was to fill this gap by developing a set of socioeconomic scenarios for the UK that is consistent with the global SSPs used by the IPCC community, and which will provide the basis for further UK research on climate risk and resilience.

United Kingdom UK: Proportion of People Living Below 50 Percent Of Median Income: % data was reported at 11.700 % in 2021. This records an increase from the previous number of 11.500 % for 2020. United Kingdom UK: Proportion of People Living Below 50 Percent Of Median Income: % data is updated yearly, averaging 11.600 % from Dec 1968 (Median) to 2021, with 54 observations. The data reached an all-time high of 13.700 % in 1993 and a record low of 4.500 % in 1968. United Kingdom UK: Proportion of People Living Below 50 Percent Of Median Income: % data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s United Kingdom – Table UK.World Bank.WDI: Social: Poverty and Inequality. The percentage of people in the population who live in households whose per capita income or consumption is below half of the median income or consumption per capita. The median is measured at 2017 Purchasing Power Parity (PPP) using the Poverty and Inequality Platform (http://www.pip.worldbank.org). For some countries, medians are not reported due to grouped and/or confidential data. The reference year is the year in which the underlying household survey data was collected. In cases for which the data collection period bridged two calendar years, the first year in which data were collected is reported.;World Bank, Poverty and Inequality Platform. Data are based on primary household survey data obtained from government statistical agencies and World Bank country departments. Data for high-income economies are mostly from the Luxembourg Income Study database. For more information and methodology, please see http://pip.worldbank.org.;;The World Bank’s internationally comparable poverty monitoring database now draws on income or detailed consumption data from more than 2000 household surveys across 169 countries. See the Poverty and Inequality Platform (PIP) for details (www.pip.worldbank.org).

United Kingdom UK: Poverty Headcount Ratio at National Poverty Lines: % of Population data was reported at 18.600 % in 2017. This records an increase from the previous number of 17.000 % for 2016. United Kingdom UK: Poverty Headcount Ratio at National Poverty Lines: % of Population data is updated yearly, averaging 17.800 % from Dec 2016 (Median) to 2017, with 2 observations. The data reached an all-time high of 18.600 % in 2017 and a record low of 17.000 % in 2016. United Kingdom UK: Poverty Headcount Ratio at National Poverty Lines: % of Population data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s United Kingdom – Table UK.World Bank.WDI: Social: Poverty and Inequality. National poverty headcount ratio is the percentage of the population living below the national poverty line(s). National estimates are based on population-weighted subgroup estimates from household surveys. For economies for which the data are from EU-SILC, the reported year is the income reference year, which is the year before the survey year.;World Bank, Poverty and Inequality Platform. Data are compiled from official government sources or are computed by World Bank staff using national (i.e. country–specific) poverty lines.;;This series only includes estimates that to the best of our knowledge are reasonably comparable over time for a country. Due to differences in estimation methodologies and poverty lines, estimates should not be compared across countries.
