RETENTION
Who came back this season
Of the swimmers who swam for Birmingham Blue Dolphins in 2024-25 — how many are here in 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.
MEET CADENCE
How much this club races, and at what level
Distinct meets the current roster swam at — counting meets, never scores
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.
