I’d say football, basketball, track and maybe soccer. The explosion of club/travel team sports has skewed most youth team sports into higher SES demos.
Football has resisted the privatization trend of youth team sports the most (although it too is changing). So football is still primarily centered around public school teams that are low cost to participate in. But even public school teams today cost more to participate in than before.
Suburban kids are many many more times likely to play team sports than inner city kids. Years later, that trend shows up in the roster composition of most college sports teams.
