Demographic snapshot

Aggregated up from the 2 of 2 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.

76.7% White British 2021 (derived)

59.4% -17.3pp White British 2051 projected (derived)

14.7% Foreign-born 2021 (derived)

43.4% Foreign-born 2051 projected (derived)

Method: each constituent local authority contributes the product of its postcode share within the constituency and its 2021 population. Underlying figures from Census 2021 (ONS custom dataset) and the Hamilton-Perry projection model. See the methodology page for the projection's limitations and validation.
