The English football pyramid is a complex structure, particularly below the National League System, and it does not always form a perfectly
linear pyramid. While the chart shows the typical progression route from one level to the next, some leagues have promotion pathways
into more than one higher division. These routes can vary depending on geographical location, the number of clubs in each division,
and decisions made by the Football Association to maintain a balanced league structure.
For simplicity, the chart displays the most common promotion route for each league, rather than every possible pathway.
