性別（gender）是與多元文化主義相關的重要議題之一。正如Susan Okin所說，私人領域既是女性的領域，也是文化的核心部分。本論文闡釋了韓國非正常的性別比例，特別是源於重男輕女思想的文化背景來觀摩性別屬性。1990年，韓國的新生兒男女性比為116.5:100，顯然是非常不均衡的比例。但是，目前韓國的新生兒性比為105:100，接近全世界新生兒的平均性比水平。1990年非正常新生兒的性比及其後出現的正常新生兒性比變化原因的闡述，對於理解韓國文化的本質屬性，特別是進而認可文化多樣性的平等主義思維轉換及家人關係的結構性變化（代際定義）中提供諸多啟示。為了探究原因，從生物學、人口統計學及人類學等觀點予以證明，並將韓國與西方及東亞國家進行比較。此外，為了從政治哲學的角度來加深了解平等主義和文化多樣性，充分利用實證資料，明確解析其含義。

Gender is central to debates about multiculturalism, since as Susan Okin argued the private sphere is both perceived as the domain of women and at the core of culture. In this paper we explore the gendered nature of culture through an examination of the phenomenon of abnormal sex ratios in South Korea, specifically the preference for sons. In fact, the ratio peaked in 1990 at 116.5:100 (at birth) and is now close to the global average of 105:100. Identifying the reasons for that abnormal ratio and its subsequent normalisation tells us important things about the nature of Korean culture, specifically the development of an egalitarian ethos conducive to greater cultural diversity and on the changing structure of family relations (intergenerational justice). The paper will draw on evidence from biology, demography and anthropology and will compare South Korea with both Western and other East Asian countries. It will use these empirical data to illuminate debates within political philosophy over egalitarianism and cultural diversity.
