The impact of population and GDP is obvious: A large population increases the chance that a country will have athletes with the natural talent to win medals, and a high GDP means that it will have the money to invest in the infrastructure and training needed to develop medal-winning athletes.
人口和GDP的影响是显而易见的：一国人口数量越大，拥有夺牌天赋运动员出生的概率就越高，而高GDP意味着一国有钱投入到开发夺牌运动员的基础设施和训练中去。
