Number of U.S. high schools with athletics programs for girls from 2009/10 to 2017/18, by sport

Recent data on the growth of girls' high school sports.  Sharing on our blog and  social media and hope you'll add your comments.  I'm curious if the emergence of development academies, the cut in school athletic budgets and the rise in club sports are curtailing growth and how these numbers compare with boys sports. Curious about the reasons behind the tremendous growth in Competitive Spirit Squads. (41%).
