Check out all of the 2021 Olympic swimming rosters with SwimSwam’s handy index here.
Over the last number of weeks, we have begun to learn the names of swimmers who have received invitations to compete at the Tokyo 2020 Olympic Games. Only a few nations have not announced their rosters yet.
Instagram’s Swimming Stats page has published the list of the largest swimming rosters for the Tokyo Olympics. The list considers swimmers of pool and open water events, since there are some swimmers who will compete in both.

There are 13 countries that will be sending more than 20 swimmers to Tokyo. Unsurprisingly, the United States tops the list, with 53 swimmers. In 2016, 47 American swimmers competed in Rio.
In fact, the top 3 countries on the list have increased their rosters. Hungary had 35 swimmers in Rio and will have 38 in Tokyo. Australia will have 37, one more swimmer in comparison to 2016.
Interestingly, Japan will bring 35 swimmers to its home-based Olympics, only one more than they did at Rio 2016.
Among the top nations, China has experienced the biggest decrease in the number of swimmers on its roster. There were 45 Chinese swimmers in Rio, the second largest roster at that Olympics. Now, there will be 30 in Tokyo.
In 2016, Brazil had the largest Olympic swimming roster in its history, with 32 swimmers. With 27 swimmers in Tokyo, it will be the largest Brazilian swimming roster in a non-home-based Olympics. This is remarkable due to the fact that, for the first time, Brazilian swimmers had only one chance to qualify for the Olympics.
Among the countries on this list, China is the one that, proportionally, has the most women in its roster: 63.3% of their entered athletes are women. On the other hand, the Polish roster has 69.6% of its athletes as men.
