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.

Coverage is a modelled postcode-level snapshot, not a speed test or a guarantee for a named property. Check availability with providers before making a decision. Ofcom does not publish postcode-level full-fibre coverage in this release for commercial-confidentiality reasons.
