## Methodology

Latest GLA Affordable Housing Programme outturn. These are GLA-funded starts and completions, not total affordable-housing supply across London, and the two stages are shown separately.

- [Overview](https://londongraph.com/g/affordable-homes-started-and-completed?view=overview): The GLA-funded programme, borough by borough, with starts kept apart from completions.
- [Distribution](https://londongraph.com/g/affordable-homes-started-and-completed?view=distribution): Place every mapped area in the selected measure's distribution while preserving missing values.
