Population projections

London population projections are updated annually at both local authority and ward level.


Note: The next release of GLA projections, the 2016-based projections, is scheduled for the week commencing 10 July 2017.


The GLA’s models and assumptions continue to evolve as new data is released and each new round of projections supersedes earlier rounds. Projections from older rounds are included here to illustrate how projections have changed over time, but where possible users should use data from the most recently produced round.

Multiple projection variants are produced to cover a range of applications. The variants can differ in the methodologies and assumptions used. The number of projection variants has increased significantly in the course of the most recent rounds. The production of these has been driven by the desire to meet the needs of a wide range of users. While multiple variants are useful for some users, the team is mindful that this proliferation can cause confusion among others as to which variant to use for their purposes.

A tool summarising the relationships between variants is available here.
