IF YOU SWITCHED

Same slice at other clubs

The comparison families actually make — not which club scores higher, but whether your swimmer would still have people to train with in this event. The two biggest MI squads for this slice, beside Birmingham Blue Dolphins: 50 Fly LCM · 13-14 girls · 2025-26.

all MI clubs pooled (91% overall)

The mid-teens drop-off is sport-wide, not one club’s story — read every row against the MI marker, never in isolation. Age groups are the swimmer’s age at the end of 2024-25; swimmers with no birth date on file are counted in All ages only. Membership is counted from published swims, so a swimmer who hasn’t raced yet in 2025-26 still counts as here while the roster carries them.

Meets are attributed through the current roster’s published swims, so a season a swimmer raced before joining Birmingham Blue Dolphins counts toward the meets they attended then. Numbers describe; they do not rank.
