How to read these estimates
The standard postcode headcounts and the commissioned age table are separate ONS outputs. Small counts are disclosure-controlled, and totals can differ slightly between tables. Coverage is England and Wales only.

Census Day: 21 March 2021. Sources: ONS/Nomis P001-P004 and ONS CT21_0228. Age table version 2024-04-08.
