The United Kingdom is one of the most unequal countries in Europe. The top 10% of households earn 3.7 times more than the bottom 10%. The richest 10% own 43% of all wealth while the poorest half own just 9%. London productivity is 26% above the national average while Wales is 17% below it. And the gap between generations — in wealth, in housing, in pension provision — has widened dramatically over the past 30 years. This page presents the data behind Britain's inequality in plain numbers.
What Is the Gini Coefficient and What Does It Tell Us?
The Gini coefficient is the standard international measure of inequality. It runs from 0 (everybody has identical income) to 100% (one person has everything). The higher the number, the more unequal the society.
The Gini coefficient for the UK was 33% before housing costs and 37% after housing costs in 2024/25. The after-housing-costs figure is higher because lower-income households spend a much larger share of their income on rent and mortgages — so housing costs widen the effective gap in disposable income.
The UK's Gini coefficient has been broadly stable since the early 1990s — after rising sharply through the 1980s under Thatcher-era policies. But "stable" at a high level still means significantly more unequal than most European peers. OECD figures suggest that the UK has among the highest levels of income inequality in Europe, although income inequality is slightly lower than in the United States.
Income Inequality — Who Earns What
A couple without children needed disposable income below £366 per week to be in the lowest-income 10% of households in 2024/25. To be in the highest-income 10% required an income 3.7 times higher — at least £1,358 per week.
The share of total income going to each fifth (quintile) of the population illustrates the concentration clearly:
In 2023/24, 35% of total disposable household income went to the fifth of individuals with the highest household incomes, while just 8% went to the fifth with the lowest. The top fifth earns 4.4 times the bottom fifth's share of national income.
The Tax and Benefits System — How Much Does It Redistribute?
The UK tax and benefit system significantly reduces inequality — but less than most European peers. Before taxes and benefits, original income inequality is far more extreme — the Gini is approximately 52%. After the full effects of taxes and benefits (including benefits in kind like NHS and education), it falls to 37%. This redistributive effect is real and substantial — but leaves the UK still significantly more unequal than Germany, France, the Netherlands or Scandinavia.
Wealth Inequality — Far More Extreme Than Income
Wealth inequality — who owns what, not just who earns what — is significantly more extreme than income inequality in the UK, as it is in most countries. Wealth accumulates over lifetimes and across generations, concentrating at the top in ways that income flows alone cannot.
Wealth in Great Britain is even more unequally divided than income. The richest 10% of households hold 43% of all wealth. The poorest 50%, by contrast, own just 9%.
The four components of household wealth have very different distributions:
Pension wealth is the largest component nationally and has become more equal since auto-enrolment was introduced in 2012 — but still heavily skewed toward higher earners with defined benefit schemes.
Property wealth is highly concentrated geographically — primarily in London and the South East, and primarily among older homeowners. First-time buyers struggle to accumulate property wealth as prices have risen faster than wages for 30 years.
Financial wealth (savings, shares, investments) is the most unequally distributed of all. In the North East, the median value of financial assets was just £2,500 — and more than one quarter of households had zero or negative financial wealth.
Regional Inequality — Britain's Deepest Divide
The UK's regional inequality is among the most pronounced of any large developed economy. The gap between London and the rest of the UK — in productivity, earnings, wealth and public investment — has widened over the past 30 years despite multiple "levelling up" agendas from governments of both parties.
The regional earnings gap is stark but the wealth gap is even wider. Average household wealth in the South East is approximately £500,000. In the North East it is approximately £168,000 — less than a third as much. This gap is driven primarily by property values — house prices in London and the South East have appreciated far faster than in northern regions, converting homeownership into a wealth-building machine for southern owners while northern owners accumulate less.
The Intergenerational Gap — How Age Became the Biggest Dividing Line
Perhaps the most significant structural shift in UK inequality over the past 30 years is the widening gap between age groups. Older cohorts — particularly those born in the 1950s and 1960s — accumulated wealth through homeownership, defined benefit pensions, and free university education at a time when these were widely accessible. Younger cohorts face the opposite: expensive housing, defined contribution pensions, and £47,000 average graduate debt.
The homeownership rate among 25-34 year olds fell from 55% in 1989 to 27% in 2024. This single statistic encapsulates the intergenerational wealth transfer that has occurred: older homeowners benefited from house price appreciation, while younger renters accumulate no property wealth and pay landlords — often older homeowners — rather than building equity.
Defined benefit (final salary) pensions — which guarantee a retirement income regardless of investment returns — have been largely closed to new entrants in both the private and public sectors. Workers who had DB pensions are dramatically more financially secure in retirement than those on defined contribution schemes, who bear all the investment risk themselves.
Does Inequality Matter for Economic Growth?
The relationship between inequality and economic growth is genuinely contested in economics. The traditional view was that some inequality creates incentives — the prospect of reward drives effort and innovation. The more recent evidence suggests that beyond a certain level, inequality actively harms growth through several mechanisms:
Reduced consumption: Lower-income households spend a higher proportion of their income than wealthy households. As income concentrates at the top, aggregate consumption falls relative to what it would be with a flatter distribution — reducing demand and growth.
Underinvestment in human capital: Children from lower-income families have worse educational outcomes — not because of ability differences but because of resource differences (tutoring, extracurriculars, school quality, parental time). This means society fails to develop the full potential of a large share of its population.
Reduced social mobility: The IFS Deaton Review (final report April 2026) found that the UK has lower social mobility than comparable European nations — a child's economic outcomes in the UK are more strongly predicted by their parents' outcomes than in Germany, France or Scandinavia. This "stickiness" at both the top and bottom of the distribution means inequality perpetuates itself across generations.
Political and social consequences: High inequality tends to increase political polarisation, reduce trust in institutions, and create conditions for populist movements. Whether this costs economic growth directly is debated — but the political consequences of the UK's regional and generational inequality are visible in recent electoral history.
