↑ The IOC site for the 2002 Winter Olympic Games gives erroneous figure of 77 participated NOCs, however one can count 78 nations looking through official results of 2002 Games Part 1, Part 2, Part 3. Probably this error is consequence that Costa Rica's delegation of one athlete joined the Games after the Opening Ceremony, so 77 nations participated in Opening Ceremony and 78 nations participated in the Games.
