TECHNICALLY SPEAKING: Earnings represent salary and/or prize money from 2011 calendar year or most recent season and excludes any other source of compensation, unless otherwise noted. If official salary figures were unavailable, earnings were based on information from multiple sources, including leagues, agents, sports federations, cultural centers and the United Nations. All figures converted to U.S. dollars as of April 3 exchange rate. Per capita GDP (Gross Domestic Product), a leading indicator of national wealth, is the market value of a country's goods and services divided by its population.
