## Methodology

Healthy life expectancy at birth for women — the years expected to be spent in good health rather than simply alive. This is the harder number and the more unequal one: the gap between the top and bottom borough is wider here than for life expectancy itself, because places that lose years also tend to spend more of the ones they keep in poor health.

## Visualisations

- [Map](https://londongraph.com/g/how-many-of-those-years-are-good-ones): Compare the same measure geographically.
- [Overview](https://londongraph.com/g/how-many-of-those-years-are-good-ones?view=overview): Richmond gets 70 healthy years. Greenwich gets 57.
- [Distribution](https://londongraph.com/g/how-many-of-those-years-are-good-ones?view=distribution): Place every mapped area in the selected measure's distribution while preserving missing values.
- [Total vs healthy years](https://londongraph.com/g/how-many-of-those-years-are-good-ones?view=relationship): Compare healthy life expectancy with total life expectancy by borough. Caveat: A spatial association does not establish that either measure causes the other.
