On Monday 18 May 2020, the Office for National Statistics (ONS) issued a notice on its website informing users that they had identified an error affecting the 2018-based national population projections.
The error was caused by incorrect processing of cross-border flows between Wales and England, resulting in the projected mid-2028 population for Wales being approximately 65,000 too low, and that for England being approximately 65,000 too high.
The ONS published corrected national population projections for Wales on Thursday 11 June.
The corrected projections are showing a different longer-term trend for Wales compared with the projections published originally. The original projections were showing a projected decrease in Wales’ population from 2025 onwards.
Revised StatsWales tables will be published as soon as possible.
