Projection

ONS national population projection

ONS projection, not a forecast by this site.

In its principal projection (National population projections: 2024-based, published 28 April 2026), ONS projects the UK population to peak at 72,528,463 in mid-2054 and to be 64,728,271 in mid-2124. From mid-2027 it assumes net migration of 230,000 a year.

A projection shows what would happen if ONS's assumptions about fertility, life expectancy and migration held. It starts from the mid-2024 estimate as first published; ONS has since revised that estimate, so the projection's early years do not match the latest estimates above exactly.
