Colleague lived in Japan for three years - they pretty much dislike most races and view them as inferior to themselves...he married a Japanese girl and that didn't go over well. Very closed-minded and distrustful of other races.
So Asians would be #1 - followed by Indians. Non-diverse societies follow these patterns.
South Korea, not very tolerant, is an outlier. Although the country is rich, well-educated, peaceful and ethnically homogenous – all trends that appear to coincide with racial tolerance – more than one in three South Koreans said they do not want a neighbor of a different race. This may have to do with Korea’s particular view of its own racial-national identity as unique – studied by scholars such as B.R. Myers – and with the influx of Southeast Asian neighbors and the nation’s long-held tensions with Japan.
• India and Jordan by far the least tolerant. In only two of 81 surveyed countries, more than 40 percent of respondents said they would not want a neighbor of a different race. This included 43.5 percent of Indians and 51.4 percent of Jordanian. (Note: World Values’ data for Bangladesh and Hong Kong appear to have been inverted, with in fact only 28.3 and 26.8 percent, respectively, having indicated they would not want a neighbor of a different race. Please see correction at the bottom of this post.)
Anglo and Latin countries most tolerant. People in the survey were most likely to embrace a racially diverse neighbor in the United Kingdom and its Anglo former colonies (the United States, Canada, Australia and New Zealand) and in Latin America. The only real exceptions were oil-rich Venezuela, where income inequality sometimes breaks along racial lines, and the Dominican Republic, perhaps because of its adjacency to troubled Haiti. Scandinavian countries also scored high.
Red countries = most racist
Blue countries = most tolerant
