The word "Athletics" has different connotations in America and the rest of the world.
In the U.S.A., "athletics" implies all competitive sports, i.e. a collegiate Athletics Department. In the rest of the (English-speaking) world, it covers the specific set of sports known in America as "Track and Field", hence the international governing body name IAAF or International Association of Athletics Federations.
(In some languages, there's a distinction between "light athletics," i.e. track and field, and "heavy athletics," i.e. weightlifting.)
At any rate: which definition should we use for the athletics tag? At the time of asking, we had one question for each definition in the tag.
This seems to overlap with How should the tag "Football" be used, but I don't think these tags should be synonyms.
