Ethnic diversity and statistics in East Asia: 'foreign brides' surveys in Taiwan and South Korea

East Asian nations have become increasingly diverse in their ethnic composition since the 1990s. A large proportion of recent immigrants consists of women from China, Vietnam, Indonesia, Thailand and the Philippines, who migrated following their marriage to male citizens from South Korea and Taiwan. To study this new group of foreign residents, the governments of both Taiwan and South Korea have conducted national surveys since 2000. This paper conducts a content analysis of the questions of these surveys to elaborate a criticism of the ethnic statistics produced from them. These surveys provide relevant information on this group of new residents, but they also have the potential to reinforce existing negative stereotypes due to prior assumptions that shaped the content of questionnaires. The analysis reveals that the production of statistics on migrants is influenced by three ideologies: assimilation, patriarchy and nationalism.
