United Kingdom Demographics

The United Kingdom combines continued population growth, low fertility, a large older-age share, high urbanization, and a recent migration balance that has changed sharply across source years.

Core population values use Office for National Statistics mid-year estimates and provisional estimates. Fertility, age-share, total life expectancy and urban indicators use World Bank World Development Indicators where comparable UK-level series are needed.

Table analysis
  • The official mid-2024 estimate is 69,281,400, while the mid-2025 value is provisional and rounded.
  • Net international migration was +738,700 in the year to mid-2024 and +204,000 in the provisional year to mid-2025.
  • The urban population share is sourced separately from World Bank WDI because the ONS population estimate is not an urban-rural series.

Fertility and Life Expectancy

Fertility Compared With Replacement Level

Total fertility rate compared with a broad 2.1 births-per-woman benchmark.

Hover or click the chart to inspect values.

Source: World Bank World Development Indicators, 2024. Replacement level is a broad benchmark and is not a country-specific projection assumption.

Chart analysis
  • The UK fertility rate is 1.551 births per woman in the 2024 WDI series.
  • The value is below the broad replacement-level benchmark of 2.1 births per woman.

Life Expectancy at Birth

Male and female values from ONS single-year life tables, with total life expectancy from WDI.

Hover or click the chart to inspect values.

Sources: ONS national life tables for male and female 2024 values; World Bank WDI for total 2024 value.

Chart analysis
  • Female life expectancy at birth is 83.3 years in the ONS 2024 single-year table.
  • Male life expectancy at birth is 79.4 years, giving a male-female gap of 3.9 years.
  • The total value comes from WDI, while the male and female values come from ONS; each row is labeled by source.

Table analysis
  • The sex-specific life expectancy rows use ONS single-year values for 2024.
  • The total row uses WDI and should not be read as a direct arithmetic average of the ONS male and female rows.

Migration and Natural Change

Population Change Components

Births, deaths, immigration, emigration and net international migration for the year to mid-2024.

Hover or click the chart to inspect values.

Source: ONS mid-year population estimates, year to mid-2024.

Chart analysis
  • Births exceeded deaths by 16,200 in the year to mid-2024.
  • Net international migration was much larger than natural change in the same period.
  • Immigration and emigration are flow measures, while total population is a stock measure.

Table analysis
  • The provisional mid-2025 release provides births, deaths and net migration, but not separate immigration and emigration totals.
  • Natural change is small in both rows compared with net migration.

Urban Population

Urban Population Share

Urban share of the total population in the World Bank WDI urban series.

Hover or click the chart to inspect values.

Source: World Bank WDI and UN urban series, 2024. Urban classification follows national definitions used in the international urban dataset.

Chart analysis
  • The urban share is 84.88% in 2024.
  • The urban population count in the same WDI series is 58,761,798.
  • Urban definitions differ by national statistical systems, so cross-country comparisons should keep the source definition in view.

Population Projection

Principal projection from the 2024 base year to selected future years.

Hover or click the chart to inspect values.

Source: ONS 2024-based national population projections. Projections are scenario-based estimates, not guaranteed predictions.

Projection analysis
  • The principal projection moves from 69.3 million in 2024 to 71.0 million in 2034.
  • The series reaches about 72.4 million by 2049.

The official population estimate reached 69,281,400 in mid-2024, followed by a provisional 69,487,000 in mid-2025.

Migration balance

Net international migration was +738,700 in the year to mid-2024, then +204,000 in the provisional year to mid-2025.

Age structure

The WDI age-share series places the 65+ population at 19.50% in 2024, above the 0-14 share of 17.19%.

Fertility pattern

Projection path

The ONS 2024-based principal projection reaches 71.0 million in 2034 and about 72.4 million in 2049.

Source caution

ONS resident-population estimates and WDI de facto or urban series use different definitions, so values are labeled by source.

Data Sources and Methodology

Population levels use ONS resident-population estimates where available. WDI provides UK-level fertility, total life expectancy, broad age structure and urban indicators. ONS 2024-based projections use a separate future population series.

Methodological Safety Note

Methodological Safety Note: ONS resident-population estimates, provisional estimates and WDI indicators use different definitions and reference periods. Urban population follows the national definition used in the international urban series.

Data Questions

What is the latest population figure used here?

The latest figure shown is 69,487,000 for mid-2025, but it is provisional. The latest official mid-year estimate used here is 69,281,400 for mid-2024.

Why do some indicators use ONS and others use World Bank WDI?

ONS is preferred for UK resident-population levels and official change components. WDI is used where comparable UK-level fertility, age-share, total life expectancy and urban indicators are needed.
