The  State of London report  brings together over 100 datasets about life in the capital – covering its economy, environment, housing market, and social outcomes such as health and education, among many other topics.  Published annually by the GLA’s City Intelligence Unit, the report’s ten chapters provide an array of charts and data, organised around the outcomes...

Modelled estimates of annual live births by year ending date. Official birth estimates from ONS are considered very accurate, but the lag between the end of the period covered and the publication of estimates is typically 9-12 months. To gain a more timely indication of birth trends, the GLA Demography team produces modelled estimates of annual births...

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...

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...

Comparison to previous MYE data The previous MYE series (for the period 2012-2020) starts with the 2011 census estimate. Each subsequent...

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...
