FIFA女子ランキング
In January 1999, FIFA introduced a revised system of ranking calculation, incorporating many changes in response to criticism of inappropriate rankings. For the ranking all matches, their scores and importance were all recorded, and were used in the calculation procedure. Only matches for the senior men's national team were included. Separate ranking systems were used for other representative national sides such as women's and junior teams, for example the FIFA Women's World Rankings. The women's rankings were, and still are, based on a procedure which is a simplified version of the Football Elo Ratings.
