Population Statistics and Analysis at the Greater London Authority
GLA Demography is a team within the GLA’s City Intelligence Unit responsible for producing a wide range of data and analyses relating to London’s current and future population.
Our datasets are organised around the following major topics:
- Population and household projections
- The history of London’s population
- Migration data
- Demographic impact of COVID-19
- School pupil data
- Fertility data
- Population yield calculator
- Useful links to other population statistics
- Technical notes
We produce a range of population projections which are used to help inform planning and policy work within the GLA and across London. Most of our projections are updated annually, incorporating the latest data as it becomes available.
We provide estimates of London’s historical population to help to contextualise our population projections and inform wider analysis.
We produce summaries for London of ONS and DWP estimates of international migration to and from the UK.
This briefing brings together a range of data published on the impacts of Covid19 in London. It summarises available information about cases and deaths, and summarises the emerging evidence of unequal impacts for different demographic groups.
We produce a wide range of demographic data relating to education in London, including projections of demand for school places and estimates of cross-border migration flows between different local authorities. Our work covers both primary and secondary provision. We also host the London Schools Atlas, an interactive online map of London providing a uniquely detailed and comprehensive picture of London schools.
We maintain several datasets relating to trends in fertility rates in London as a whole, and for small areas within London.
The GLA Population Yield Calculator is a tool for estimating population yield from new housing development. The calculator provides users with an indication of the size and age distribution of the population that might be expected to live in a new housing development based on bedroom and tenure mix.
We provide a range of links to other useful sources of data on London’s population, both within the GLA and from other organisations.
Additionally, we also host a set of technical notes which relate to the methodology behind how some of our population datasets are produced. Please note that individual data releases often contain an explanation of the methodology behind them which is likely to be the most thorough source of this kind of information.
