When is a Russian not a Russian? Russia is banned from the Winter Olympics. However, there is a group of non-Russian Russians - Team 'OAR' - Olympic Athletes from Russia who are competing. There are 169 of them.
They are competing under the Olympic flag, and the Olympic anthem will be played at their medal ceremonies. They will be allowed to display the Russian flag in their bedrooms, so long as this is not publicly visible. The BBC article is HERE
The Winter Olympics is slanted towards northern climate countries - 242 athletes from the U.S., 225 from Canada. Germany has 153 athletes. Great Britain a mere 59 in comparison, though this is their largest team so far.
Russia had 232 competing in Sochi. In this Games, there are now 169 Non-Russian Russians.
Consider the 2016 Summer Olympics, where Great Britain had 366 athletes, Canada 314, and the United States 554. Japan had 338. Brazil, the host, had 465. There were 972 medals given out.
How many medals will be given out in the 2018 Winter Games? There are 102 events, so it appears that there could be 306 medals awarded. However, the official Olympic website says that 259 sets of medals have been made. Some of these 102 events are exhibition events.
More on the medals from the Olympic site: "The medals, which range in weight from 586 grams for the gold medal to 493 grams for the bronze, reflect the traditions and culture of the host nation. Their design was inspired by the texture of tree trunks, with the front bearing the Olympic rings and dynamic diagonal lines that reflect both the history of the Olympics and the determination of the participants. On the reserve (I think it should be reverse*), meanwhile, are stated the discipline, event and the PyeongChang 2018 emblem. In total, 259 sets of the medals have been made."
*A search on the 'reserve' of a medal retrieves 'reserve price' of $35,000, a 'reserve' of medals kept by the IOC, and 'Reserve' Forces medals. There's no reserve identified in the wikipedia entry on medals.
