Sports bring people together, evoke national pride and are a hugely important part of many cultures. From casual games in the park to international events like the Olympics or Football World Cup, they can impact political, economic and other cultural aspects of a country or region.

The global popularity of sport reflects the diverse range of interests that are shared by people across the globe. While some of the most popular international sports are relatively recent inventions, others, such as wrestling or archery, have been around for millennia.

While international sport has brought people together, it is also fraught with inequality. Where you come from can have a major influence on how far you go, with some athletes benefiting from better medical care and more support than others. For example, a study found that young East African athletics competitors were more likely to die of a heart attack than their European counterparts, partly due to lack of support and access to training facilities.

In the case of the Olympic Games, there are a number of factors that influence where the event will be held. The most important is a country’s ability to raise the funds required to build the necessary facilities. It is for this reason that the Games are almost always held in High Income Countries or Middle Income Countries that are fast developing.

In addition, the International Federations – organisations that administer one or more sports on an international level – must ensure their statutes, practice and activities are in accordance with the Olympic Charter. These federations can formulate proposals addressed to the IOC concerning the Olympic Charter and the organisation of the Olympic Games; give their opinions regarding the candidatures for organising the Olympic Games; collaborate in the preparation of the Olympic Congresses; and participate in the activities of the IOC commissions.
