Study of Trends in Youth Sports

I found this study done a back in 1996 highlighted some interesting trends:

"The National Council of Youth Sports (NCYS) is a multi-sport corporation established to foster the continued education of youth sport administrators, and to support the growth and development of youth through participation in organized youth sports....

SURVEY STATISTICAL RESULTS

NCYS Member Participation Numbers:

Total number of youth participants
44,962,126

Total number of coaches
2,453,607

Total number of volunteers
7,609,794

Total number of participants involved in organized youth sports
55,025,527

Total overall participation breakdown by gender:
Boys 63%, Girls 37%

As a result of this survey, an observation can be made that boys begin participating in youth sports 3-4 years earlier than girls. This might suggest boys are provided with more opportunities at an earlier age or that perhaps it is sociological and boys are encouraged to participate sooner. It can further be noted that participation by girls increases when they reach high school. This seems to indicate that when given an opportunity in organized youth activities, girls do participate and that Title IX has had an effect on increasing participation. "

How do you guys think Title IX has influenced the participation of young girls in sporting events? Obviously this study was dated so it would be interesting to see if the 3-4 year head start boys were getting has been narrowed considerably or if it is still prevalent today.
