== Statistical information == These tables present the number of [[singles (tennis)|singles]] (S) and [[doubles (tennis)|doubles]] (D) titles won by each player and each nation during the season. The players/nations are sorted by: 1) total number of titles (a doubles title won by two players representing the same nation counts as only one win for the nation); 2) a singles > doubles hierarchy; 3) alphabetical order (by family names for players).
