England League
The English football league system, also known as the football pyramid, is a series of interconnected leagues for club football in England (although for historical reasons a small number of Welsh clubs also compete). The system has a hierarchical format with promotion and relegation between leagues at different levels, and allows even the smallest club to dream of rising to the very top of the system. There are over 140 leagues, containing over 480 divisions. The exact number of clubs varies from year to year as clubs join and leave leagues or fold altogether, but an estimated average of 15 clubs per division implies that over 7,000 clubs are members of a league in the English football league system.

About the system
  The system consists of a hierarchy of leagues, bound together by the principle of promotion and relegation. Clubs that are successful in their league can rise higher in the pyramid, whilst those that finish at the bottom can find themselves sinking further down. In theory it is possible for a lowly local amateur club to rise to the pinnacle of the English game and become champions of the Premier League. While this may be unlikely in practice (at the very least, not in the short run), there certainly is significant movement within the pyramid. The number of teams promoted between leagues or divisions varies, and promotion is usually contingent on meeting criteria set by the higher league, especially concerning appropriate facilities and finances.
  The top five levels contain one division each. Below this, the levels have progressively more parallel leagues, which each cover progressively smaller geographic areas. Many leagues have more than one division. At the lower levels the existence of leagues becomes intermittent, although in some areas there are as many as twenty layers. There are also leagues in various parts of the country which are not officially part of the system as they do not have formal agreements with other leagues, but are recognised at various levels by county football associations. Clubs from these leagues may, if they feel they meet the appropriate standard of play and have suitable facilities, apply to join a league which does form part of the system.

Structure
--------------------------------------------------------------------   At the top is the single division of the Premier League (which is sometimes referred to as Level 1 of the league 'pyramid'), containing 20 clubs. Below the Premier League is The Football League, which is divided into three divisions of 24 clubs each: The Championship (Level 2), League One (Level 3) and League Two (Level 4). The 92 clubs in the Premier League and Football League are all full-time professional clubs. Confusingly, all are often referred to as 'League' clubs because, before the establishment of the Premier League in 1992, the Football League included all 92 clubs, in four divisions. Clubs outside this group are referred to as 'non-League' clubs, although they too play most of their football in league competitions.
  The top tier of non-League football is the Football Conference, which contains a national division of 24 clubs (Level 5), followed by two divisions at Level 6, covering the north (Conference North) and south (Conference South), with 22 clubs each. Some of these clubs are full-time professional and the others are semi-professional. Below the Conference some of the stronger clubs are semi-professional, but continuing down the tiers, soon all the clubs are amateur.
  Next down from the Football Conference are three regional leagues, each associated with different geographical areas, although some overlap exists. They are the Northern Premier League (which covers the north of England), Southern League (which covers southern England, the Midlands and parts of Wales) and the Isthmian League (which covers the south east). All of the leagues have a Premier Division (Level 7) with two parallel divisions below (Level 8).
  Level 9 contains the top divisions of a large group of sub-regional leagues. Each of these leagues has a different divisional set up, but they all have one thing in common: there are yet more leagues below them, each covering smaller and smaller geographical levels.
