Summary

This page contains results of recent projections produced by the GLA that have been designated as research outputs rather than as a full entry in the GLA's annual series of projections.Update - 29 May 2026An updated set of trend-based projection outputs have been added. These include adjustments to the underlying estimates of population and international migration of children to address recently identified issues with the official series.Update - 6 August 2025Initial 2024-based trend projection outputs have been added. For more information, please see this blog post.*****The decision not to give a full release to the 2023-based projections was a consequence of problems with official population estimates used as inputs to the models; they are set to be updated later in 2025 once updated estimates are released by ONS.These outputs were produced in April 2025 as part of the population and pupil projection services that the GLA offers to local authorities in London and are presented here to:· Indicate the potential scale of impacts that recent updates and revisions to Long-Term International Migration (LTIM) estimates for the UK may have on the final projections.· Demonstrate the results of a newly introduced methodology for projecting future fertility rates.· Provide users an opportunity to give feedback on the updated set of projection variants being considered for inclusion in future releases.· Be used as model inputs during the development of the GLA’s upcoming household projections.A note providing an overview of the results of and background to these projections will be added in the coming weeks.The GLA's 2022-based population projections are available here.
