Monday Trivia, No. 139 [Nob Akimoto wins!]
Within Europe, the leader is France. In descending order thereafter, we have Italy, Germany, United Kingdom, Spain, Belgium, Netherlands, Switzerland, Sweden, Denmark, Portugal, Austria, Luxembourg, Ireland, Monaco, Finland, Greece, Norway, Czech Republic, Hungary, and Poland.
Outside of Europe, the leader is Japan, followed by the United States and then the People’s Republic of China.
This is a comprehensive list, current as of 2012 except for Denmark, Finland, Germany, Poland, and Sweden, for which data is current as of 2013. (Seemed like I ought to use the most current data available.)
