English football league system
The top tier of non-League football is the National League. It contains a national division (National League) of 24 clubs (Level 5), and is the lowest level with a single nationwide league. There are two divisions at Level 6, covering the north (National League North) and south (National League South), with 22 clubs each. Some of these clubs are full-time professional and the others are semi-professional. Below the National League, some of the stronger clubs are semi-professional, but continuing down the tiers, soon all the clubs are amateur. Lower-level leagues also tend to cater for progressively smaller geographic regions.
