## Statistical information

These tables present the number of singles (S) and doubles (D) titles won by each player and each nation during the season, within all the tournament categories of the 1986 ATP Challenger Series. 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).
