Within members of the global village, affluent or poor nations alike, the family structure has undergone a dramatic change. Taiwan is no exception. In the past, the traditional Taiwanese family secures social order by fusing social forces adhesively. However, accompanied with economic development, feminist movement and population immigration, the traditional Taiwanese family structure has undergone a dramatically change. The traditional family has faced colossal challenges; the increased unwedded mothers, sky-high divorce rate, separated family due to parents working in the both side of the Taiwan Strait. All of these contribute towards making the single parent family as a "social fact" in the trend of Taiwan social change.
