- 受疫情影响，2020东京奥运会将延期至2021年举行；
- 虽然延期，但此次奥运会依旧会沿用「2020东京奥运会」这个名称；
- 这也将是奥运会历史上首次延期（1916年、1940年、1944年曾因一战，二战停办）；
既然奥运会延期了，那我们就来回顾下整个奥运会的历史吧??～
本项目将会从以下角度来呈现奥运会历史：
- ?各国累计奖牌数；
- ⚽️各项运动产生金牌数
- ⛳️运动员层面
- 参赛人数趋势
- 女性参赛比例趋势
- 获得金牌最多的运动员
- 获得奖牌/金牌比例
- 各项目运动员平均体质数据
- 主要国家表现
- ??中国表现
- ??美国表现
- ?被单个国家统治的奥运会项目

- 运动员平均年龄最大的项目是Art competition（自行百度这奇怪的项目），平均年龄46岁，除此之外便是马术和射击，男子平均年龄分别为34.4岁和34.2岁，女子平均年龄34.22岁和29.12s岁；

被单个国家统治的奥运会项目
很多运动长期以来一直是被某个国家统治，譬如我们熟知的中国??的乒乓球，美国??的篮球；
此次筛选了近5届奥运会（2000年悉尼奥运会之后）上累计产生10枚金牌以上且存在单个国家「夺金率」超过50%的项目；
- 俄罗斯??包揽了2000年以后花样游泳 & 艺术体操两个项目上所有的20枚金牌；
- 中国??在乒乓球项目上获得了2000年之后10枚金牌中的9枚，丢失金牌的一次是在04年雅典奥运会男单项目上；
- 美国??在篮球项目上同样获得了过去10枚金牌中的9枚，丢失金牌的一次同样在04年，男篮半决赛中输给了阿根廷，最终获得铜牌；
- 跳水项目上，中国??获得了过去40枚金牌中的31枚，梦之队名不虚传；
- 射箭项目上，韩国??获得了过去20枚金牌中的15枚；
- 羽毛球项目上，中国??获得了过去25枚金牌中的17枚；
- 沙滩排球项目上，美国??获得了过去10枚金牌中的5枚；
