Watch United Kingdom's population change in real time. These counters estimate births, deaths, and migration activity every second based on annual demographic rates.

Key terms

Real-time counters: — Live estimates derived from annual demographic rates evenly distributed throughout the year.
Natural change: — Net change from births minus deaths (excluding migration).
Net migration: — Balance of people moving into vs. leaving the country.
Population growth: — Total change combining births, deaths, and migration.

Understanding the live counters

These real-time estimates model demographic activity based on annual rates from 2025. The population is growing, changing by about 0.01 people every second.

Rates are averaged across the year, so actual daily counts will fluctuate.
Unexpected events (pandemics, disasters, policy changes) can shift these numbers quickly.
Migration plays a significant role in net change alongside births and deaths.
