The FIBA World Rankings are FIBA's rankings of national basketball teams. FIBA ranks men's and women's national teams in both senior and junior competitions. It also publishes combined rankings for all competitions involving both sexes. Not included are rankings for three on three, which are tabulated for individual players. CalculationOnly FIBA tournaments consisting of full five-a-side teams are used in calculations for the rankings. Other tournaments, such as regional championships, invitationals, three on three half court basketball, and friendlies are not included.[2] In 2017, FIBA radically changed its ranking system for men's national teams, switching from the previous competition-based system to a game-based system. Every game played by a national team within the last eight years in the World Cup, Olympics, continental championships, and qualifiers for these events figures into the calculations.[3] Until the 2016 Olympic Games, the Olympics and the men's world championship gave identical scores for being a world champion and an Olympic chamption, but since the new FIBA ranking system was launched, these two tournaments devalued the score, changing from 5 points for both Olympic and World champion, to 2.5 points for playing in a World championship, and 2 points for playing in an Olympic game since 2017. Therefore, both tournaments will not grant a differential score with respect to others tournaments of National Teams, as they did in the past where there was no difference in points in the ranking for being world champion or Olympic champion, but if there was much difference until 2016 in FIBA ranking points between these two tournaments and the rest of the competitions in FIBA, such as the continental tournaments. For women FIBA will continue maintaining the score of 5 points for playing an Olympic or world championship game. Rating points per gameEach game in a ranking tournament is initially valued at 1,000 basis points, divided between the two teams as follows:[3]
The basis points are adjusted based on the site of the game, with FIBA calling this adjustment home/away points. During the finals of ranking tournaments, only games played by a host team in its own country count as "home" games; all others are treated as neutral-site games. Adjustments are:[3]
The basis points are also adjusted to reflect the strength of the opponent. FIBA determines what it calls opposition ranking points by the following formula:[3]
A team's final rating points for a particular game is the sum of basis, home/away, and opposition ranking points.[3] WeightingThe new calculations still account for the specific tournament and region, as in the former procedure, but no longer explicitly consider a team's final tournament placement. In a new feature, a time decay factor has been introduced into the calculations. More recent games carry the greatest weight, steadily declining until falling out of the calculations after 8 years:[3]
Regional weighting remains in the system, though the specific factors vary from those used in the past men's rankings: Until the Olympic Games in 2016, the Olympics and the men's world championship gave identical scores for being a world champion and Olympic champion, but since the new FIBA ranking in 2017 these two tournaments devalued the score, changing from 5 points for both Olympic and World champion, to 2.5 points for playing in a World championship, and 2 points for playing in an Olympic game since 2017. Therefore, both tournaments will not grant a differential score with respect to others tournaments of national teams, as they did in the past where there was no difference in points in the ranking for being world champion or Olympic champion, but if there was much difference until 2016 in FIBA ranking points between these two tournaments, and the rest of the competitions in FIBA, such as the continental tournaments. For women FIBA will continue maintaining the score of 5 points for playing an Olympic or world championship game. Events' weights
FIBA uses a weighted arithmetic mean (with a minimum divisor which is not published[4]) to determine the statistical weight of each tournament. Each event is assigned a point weight that is based partly on how competitive the tournament is and partly on which national teams are participating:.[2] There were constant changes in the system of the FIBA ranking, but it can be seen that until 2016 the FIBA World Championship and the games awarded the same points in the FIBA ranking, therefore the FIBA World Championship and the Olympic basketball games had the same value. Therefore, for those years the World Cup and the Olympic tournament had the same prestige according to the ranking of those years. In the year 2017, according to the ranking system in the FIBA ranking, published on October 11, 2017 for the first time in history, the FIBA World Championship awards more points than the Olympic tournament: 2.5 points the world championship, against 2 points the Olympics games. For all this the FIBA 2019 World Championship will be the first more prestigious championship than an Olympic basketball, given that it will be worth 2.5 points and the Olympic 2020 worth 2 points. The 2017 FIBA ranking started on October 11, 2017. Since that date, the FIBA World Cup is worth 2.5 and the Olympic Games are worth 2 points, although the new ranking published on October 11, 2017 is not applicable to the tournaments played until 2016, with both tournaments maintaining the same score (5 each per game). In the future, the World Cup will be worth 2.5 points and the Olympic basketball tournament games worth 2 points, therefore in 2019, for the first time in history, the FIBA World Cup will give more points than an Olympic basketball game. In addition to the qualifying rounds, in Europe are also included the results of the FIBA European Championship for Small Countries. FIBA world Ranking for men. Events weight until 2016
FIBA world ranking for men. Events weight since 2017:[5]
From 2017 forward, FIBA Asia and FIBA Oceania members compete for a single regional championship under the FIBA Asia banner. Results from the 2010–2016 period, during which FIBA Asia and FIBA Oceania held separate championships, will continue to figure into the rankings until results from 2016, the final year of separate championships in the two regions, drop from the calculations in 2025.[3] In a new feature, FIBA also weights game results by the competition stage.[3]
Additionally, FIBA has added a round weighting to the system, giving each game in a final tournament (World Cup, Olympics, or continental championship) a weighting based on the round in which it takes place. Qualifying matches for these tournaments implicitly carry a round weighting of 1.0.[3]
If a competition does not have a round of 16 and/or a quarterfinal round, the results from the rounds that are held are scaled according to the number of rounds, with the group stage remaining at a 1.0 weighting and the competition final remaining at 2.0.[3] The final weighting is the product of the time decay, regional, competition stage, and round weights.[3] Cycle and updatesRankings are now updated after every individual game in a ranking tournament (including qualifiers for such tournaments). ExamplesFor examples of the new ranking calculations, see this page on FIBA's official site. Women's rankings{{Main|FIBA Women's World Ranking}}FIBA still uses the competition-based system to determine its women's rankings. As noted above, this system was also used to determine men's rankings prior to 2017. FIBA has announced that it will introduce a game-based ranking procedure similar to that currently used for men's rankings in the indeterminate future.[6] Notes and references1. ^{{cite web|url=http://www.fiba.basketball/rankingmen|title=FIBA Ranking Presented by Nike|publisher=FIBA|access-date=27 February 2019}} {{International basketball}}{{International women's basketball}}{{Sport world rankings}}2. ^1 FIBA.com: How it works 3. ^1 2 3 4 5 6 7 8 9 10 {{cite web|url=http://www.fiba.basketball/documents/rankingmen/howitworks |title=FIBA World Ranking Men, presented by Nike — How it works |publisher=FIBA |accessdate=12 October 2017}} 4. ^{{Cite web|url=http://www.fiba.basketball/documents/rankingmen/examples|title=Detailed Examples|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 5. ^http://www.fiba.basketball/es/news/new-fiba-world-ranking-men-presented-by-nike-launched 6. ^{{cite web|url=http://www.fiba.basketball/documents/rankingmen/faq |title=FIBA World Ranking Men, presented by Nike – Frequently Asked Questions (FAQ) |publisher=FIBA |accessdate=16 October 2017}} 3 : FIBA|Sports world rankings|Basketball rankings |
