While adult volleyball participation has remained relatively flat this decade, the region has seen an explosive growth in youth volleyball.  Based on numbers from the Fairfax County Neighborhood and Community Services (NCS) Department, between 2010 and 2017, almost twice as many girls and boys in grade school participated in volleyball programs across Fairfax County, the largest county with 40% of the NoVA population.

The number club volleyball teams in the Chesapeake Region Volleyball Association (CHRVA) has seen strong growth over the decade, increasing by an incredible 200 teams between the 2010 and 2018 seasons. This growth is inline with the same strong growth in the number of recreational volleyball players in NoVA.  The CHRVA region includes NoVA, Washington DC, Maryland and Delaware. 

Based on  National Federation of State High School Associations (NFHS) surveys, the number of girls playing volleyball in HS has increased over the decade.  The increase is observed in both the total number of schools with volleyball programs and the total number of girls playing HS volleyball.  In 2016, volleyball surpassed basketball as the most popular sport for HS girls.
