ALLAN: I have absolutely no education and am very easily confused! However, the standard of deviation would revolve around the fact that there are very, very affluent areas of the areas that Gilbert pulls from (e.g., Lake Murray communities) and very, very less affluent areas.) Thus the need for assistance, which tends to be heavily correlated with income, would be very low in areas with $1M+ homes and very high in areas with mobile homes.
Hurst66: If they're on Lake Murray, then they're probably the norm; otherwise they'd probably be the exception -- Gilbert tends to be pretty rural.
Regarding the Lexington question, LCSC (the Lexington select club) can best be thought of as a collection of teams held together by a loose organizational entity known as a "club." The two Lexington recreation clubs are separate. Lexington doesn't tend to "pull" players in the numbers that some other clubs do. As I've noted in other, club-related threads, Lexington is one of the greatest relatively untapped resource in terms of youth soccer around.
