Annual # of Soccer Teams
Here’s an ongoing list of the number of teams at each level of men’s outdoor soccer in the US and Canada (and occasionally the Caribbean) since the start of (the) Major League Soccer in 1996. For anyone asking, I don’t include the NPSL because I don’t take the NPSL seriously. Supposedly they had 48 teams in 2012 or something, some of which played as many as six games. When they showed up for scheduled games at all.
