## Methodology

Annual entries and exits at National Rail stations in London, from the Office of Rail and Road via the London Datastore. This counts National Rail, not the Underground — a station like Waterloo is both, and only its mainline passengers are here. The latest published year is 2018-19, so these are pre-pandemic figures and are labelled as such rather than presented as current.
