Demographic snapshot

Aggregated up from the 1 of 1 constituent local authority profiles, weighted by share of constituency postcodes and 2021 population. Indicative only: a constituency that takes the dense core of an LA but a small share of its postcodes will be misweighted. For direct Census observations, use the local-authority pages linked below.

72.6% White British 2021 (derived)
48.1% -24.5pp White British 2051 projected (derived)
