For Reference, there are 199 Schools that sponsor at least 1 MPSSAA sport. 168 field a Boys Lax team and 162 field a Girls lax team. Of those 162, 155 fielded a team for the state tournament this year. There were 41 Teams in 4a (38 in State Tourn.), 40 in 3A (39 in State Tourn.), 43 in 2A (40 in State Tourn.), and 38 in 1A (all 38 in State Tourn.) So it is pretty even numbers wise.

Largest 4A School: High Point-PG
Smallest 4A School: Northwood-Mtg.
Largest 3A School: Frederick HS-Fred.
Smallest 3A School: City College- Balt City
Largest 2A School: Edgewood- Harford
Smallest 2A School: Century- Carroll
Largest 1A School: McDonough-Charles
Smallest 1A School: Kent County-Kent

There are 7 schools with bigger populations than S.P. in 3A
There are 7 schools with bigger populations than Man Valley in 2A
There are 12 schools with bigger populations than Glenelg in 2A
Century is the smallest 2A school by population

All this shows is school size means nothing. Any of the above 4 schools would dominate both 4A and 1A and would have little trouble in 3A.
