Summary

The GLA Interim 2021-based population projections (January 2023) comprise both trend-based variant projections and housing-led scenario projections. This dataset contains the detailed methodology documentation for the model and is published alongside the population projections data to assist users in understanding the projections and identifying which set of projections is most appropriate for their needs.

The projections themselves can be downloaded here: Population and Household Projections
