Balance of London v2025.07.30

Info

This map shows where there is a mismatch in city-wide public transport accessibility vs local access. It indicates where further study into densification or accessibility provision could be made.

For example: if an area has a lot of local jobs compared to other parts of London but has relatively little access to city-wide jobs, it could benefit from more accessibility. If an area has great city-wide connectivity to jobs but locally is quite sparsely populated by jobs, it could benefit from more local development and investment.
