Beyond Deptford

A century of London’s population

London grew, shrank and grew again over the past century.
Its boroughs changed with it.

Data source: GLA/ONS, 1921–2021

Data and methodology: Population data come from the GLA Historical Census Population dataset and use today’s borough framework. The chart plots every available observation from 1921 to 2021. Thread width is proportional to borough population at each observation; curves between years are visual interpolation only. The 1939 figure is a mid-year estimate. Population definitions change across the series, from persons present to residents and later usual residents.
