GLA Demography has published 2016-based employment-led projections for London which provide population projections which are consistent with the employment projection scenarios published by GLA Economics. However, this should be viewed as an experimental output which may not be updated in the future. In addition to the raw data for this set of population projections, we have also produced a methodology document which explains how these projections were produced. GLA Demography produces a variety of different types of population projections in order to meet the needs of a wide range of users. To see our full range of population projections, please visit our Population and household projections homepage.

Its population of 7.75 million is 12.5 per cent of the UK population living on just 0.6 per cent of the land area. London’s average population density is over 4,900 persons per square kilometre, this is ten times that of the second most densely populated region. Between 2001 and 2009 London’s population grew by over 430 thousand, more than any other region, accounting for over 16 per cent of the UK increase. This report discusses in detail the population of London including Population Age Structure, Fertility and Mortality, Internal Migration, International Migration, Population Turnover and Churn, and Demographic Projections. Population and Migration report is the first release of the Focus on London 2010-12 series. Reports on themes such as Income, Poverty, Labour Market, Skills, Health, and Housing are also available.

Mid-year population estimates and components of change for years 2002-2020. Data for Local authority districts in England and Wales (2021 boundaries) and national data for Scotland and Northern Ireland. Data has been compiled from ONS, NRS and NISRA outputs. This is an rds file for use with R and RStudio. This is a large file (19Mb).

At the April 2023 meeting of the Population Statistics User Group, the GLA Demography team presented an overview of currently available sources of population estimates for the previous decade, namely: The original ONS mid-year population estimates (including rolled-forward estimates for 2021) Experimental outputs from the ONS's Dynamic Population Model The modelled population backseries produced by the GLA to act as inputs to our 2021-based interim population projections The slides from the presentation are published here together with packages of comparison plots for all local authority districts and regions in England to allow users to easily view some of the key differences between the sources for their own areas. The plots also include comparisons of the Dynamic Population Model's provisional 2022 estimates of births with the modelled estimates of recent births produced by the GLA.
