Today I’ve made available my entire ATP and WTA ranking databases through the end of the 2014 season. In addition, you’ll find my complete player tables, which include birthdate, country, and handedness for every player who has ever been ranked or played a tour-level match. (Plus thousands more players, who are included in the database for other reasons.)
This is all the data you need to research all sorts of topics, like the rise and fall of certain countries in the rankings and the changing age of top 10s, 50s, and 100s.
This is the third major dataset I’ve published this week, and more is on the way.
