On the WTA Tour there is a youth movement, as younger players are trying to work their way up to the top of the game. While the top 20 is dominated by older, more experienced players, the percentage of players under 25 years of age jumps dramatically as we look deeper into the rankings. In the top 20 only 20% of the players are under 25; 40% of the top 50, 44% of the top 100 and 55% of the top 200 are under 25 years of age.
Just looking at the top 20 from 10 years ago we see a huge difference in average age.
