Greater London Authority (GLA)

Modelled counts of patients registered at a GP practice by single year of age (0-95+), sex, and local authority of residence. These modelled data contain information from NHS Digital, licenced under the current version of the Open Government Licence: Counts of patients by practice attended x sex x LSOA of residence - currently published quarterly Counts of...

This dataset is now out of date: it shows the most common languages by borough and MSOAs in London based on 2011 Census. Up to date data are now available from 2021 Census but have so far been published only for London boroughs not wards, MSOAs, or local areas. We have published a report on Languages spoken in London and additional...

These modelled annual population estimates were created for use the GLA's population projections. They are intended to provide a consistent series of annual population and components of change between census years with all change accounted for by the standard components of change (births, deaths, and migration). The official mid-year population estimates published by ONS are available here. The original detailed internal migration data...

Estimated age specific fertility rates for local authorities, ITL (level 2) subregions, and regions in England and Wales. Rates modelled by the GLA using published ONS data on births by age of mother and annual population estimates. All data is published on 2021 geographic boundaries.

Introduction The 2023 mid-year estimate (MYE) is the current official estimate of the population for local authorities in England and Wales. Estimates are produced annually by the Office for National Statistics (ONS) and the 2023 MYE was published on 15 July 2024. Comparison to previous MYE data The previous MYE series (for the period 2012-2020) starts with the 2011 census estimate. Each subsequent...

The Office for National Statistics (ONS) publishes data on the number of live births by the mother's country of birth in England and Wales each year. Every time a birth is registered in England and Wales both parents are required to state their places of birth on their child's birth certificate, and this information is then...

The housing-led projections reconcile future population growth with available housing supply by incorporating a housing supply trajectory. The housing-led projections are recommended for most local planning purposes, and the 10-year variant can be considered the default variant. For most users, we recommend accessing the projections through the London Projections Explorer tool. Users...

The trend-based projections include a range of variants based on different assumptions about future levels of migration. The projections are produced for all local authorities in England & Wales. The datasets include summary workbooks with population and summary components of change as well as zip archives with the full detailed outputs from the models, including components of change by single year...

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 Population Yield Calculator is a tool for estimating population yield from new housing development. The calculator provides users with an indication of the possible number and age of children that could be expected to live in a new housing development of a given bedroom or tenure mix. Please see the calculator’s methodology document for further details and...
