Sources and interpretation
ONS · 2022-based principal projection. Births, deaths and net migration use annual baseline projections from the UK Office for National Statistics. Population is rebased to this dashboard’s 2025 estimate and accumulated from rounded annual balances. Scenario, not forecast.
The 2025 baseline is this dashboard’s estimate. Future population is accumulated from rounded annual balances, so these values can differ from the publisher’s original population series. These projections describe scenarios, not forecasts. The 35 tracked countries are not an exact geographic total for Europe.
