County attribution uses each player's latest-known club, so the early decades understate clubs that have since closed — recent years are exact, the far left of the chart is indicative. The two marked breaks are changes in the national list definition, not local events. Full caveats on the methodology.

Hertfordshire, club by club
Every Hertfordshire club with rated players on the current list, including school and junior organisations, with their July 2019 and June 2022 figures for the before-and-after.
