Interesting stats from the 2013 World Championships:
The United States led all countries in overall medals in Moscow, as American athletes earned six gold, 14 silver and five bronze medals. The U.S. has led the Championships in total medals every year since 2005. The American total of 25 medals matched its haul from 2011, but the six gold medals marked the nation's lowest total since it won five in 2001.
World Championships host Russia led all nations with seven gold medals. That's the second-best Championships performance for Russia since it began competing individually in 1993 following the breakup of the Soviet Union. Russia claimed nine golds in 2011.
Jamaica's six gold medals were the second-most in national history, behind the seven it earned in 2009. Jamaica has won 17 of its 24 World Championships gold medals in the last three Championships. Usain Bolt has contributed to almost half of Jamaica's recent gold-medal tally, earning five individual golds and running on three victorious relay teams since 2009.
Kenya's five gold medals tied for its second-best performance, behind the seven it won in 2011. Kenya has earned at least one gold in every Championships except the first, in 1983. Germany's four gold medals were the most it's won since 1999. The three gold medals won by Great Britain matched the most it's ever gained in a single World Championships. The British team also won three golds in 1993.
Ethiopia has won at least one gold medal in every World Championships since 1993. The three gold medals it gained in 2013 tie for the most in national history, while the 10 overall medals it won are the most the country has ever gained in a single Championships.
The Czech Republic, which hadn't earned a World Championships gold medal since 2007, earned two golds in Moscow. Sweden gained its first gold medal since 2007. Teddy Tamgho's triple jump victory gave France its first gold medal since 2005. Ireland won its third World Championships gold medal, and its first since 1995. Trinidad and Tobago won its first gold medal since 1997, and its second overall, with Ato Boldon claiming the initial gold in the 200 meters. Uganda also won its second gold, the previous coming in 2005 when Dorcus Inzikuru won the women's steeplechase.
Colombia earned its first-ever World Championships gold medal, thanks to Caterine Ibarguen's triple jump victory. Colombia didn't earn any Championships medals until it gained a pair of bronzes - including one by Ibarguen - in 2011.
Valerie Adams won her fourth consecutive shot put gold medal, giving her all but one of New Zealand's World Championships gold medals - Beatrice Faumuina won the discus throw in 1997. Adams also has five of her country's six all-time medals, including a bronze in 1995.
