Gold Medal Ranking in SEA Games 1959-2017
license: gpl-3.0

A bump chart for gold medals in Southeast Asian Games, just like the Olympic Games but for the region of Southeast Asia. In the recent years, there is a criticism that host countries (marked in circles) often won the most (or the second most) gold medals. Only the top 5 countries with the most accumulative gold medals are highlighted in colors.

The data are manually compiled from each page of the games in Wikipedia. Due to previous political situations in the countries in this region, many have changed their names, such as Burma to Myanmar, Malaya to Malaysia, and Cambodia to Khmer Republic. Some skipped a few games. Or a portion of the country as known now such as South Vietnam was represented in some games. The games itself was called Southeast Asian Peninsular Games from 1959 to 1975. This visualization uses the current names and tries to match any regions formerly known otherwise to their closest names. Please report any errors if you find one.
