Notes

Rating

Ratings are based on ranking every constituency with data and using the following percentiles:

  • ★★★★★ 80-100%
  • ★★★★ 60-80%
  • ★★★ 40-60%
  • ★★ 20-40%
  • ★ 0-20%

There are some cases where more is not better. In those cases we have flipped the ranking so that a lower relative value would receive more stars. For example, a child poverty rate of 0% would be ★★★★★.

We try to update datasets when there is a new release. If you know of a more recent update to a dataset, please let us know.

Any dates given in the attribution are the date of the most recent data, which can lag the release date of the dataset.
