社會福利政策的發展牽涉到家庭、市場、政府以及自願性部門角色輕重的重整;但不可否認的,社會政策的規劃應該有詳實的本土資料作爲基礎,以確實發揮功能。台灣家戶組成與特性在1976年至2004年這近三十年間出現顯著的變化,本文主要的目的即在於利用1976至2004年家庭收支調查的資料,分析台灣家戶組成、經濟戶長特性及家戶經濟特性的變遷趨勢。主要發現如下:(1)一世代家戶比率上升;(2)家戶規模縮小,未滿18歲子女減少是主因;(3)單人戶、夫婦家戶、單親家戶、祖孫家戶比率上升;(4)老年經濟生活趨於獨立;(5)單親家戶質變與量變;(6)祖孫家戶經濟情況差;(7)核心家戶就業人數增多。
The development of social welfare policies is related to the reconfiguration of the relative roles played by the family, market, government, and volunteer sectors of society. These policies cannot be fully optimized unless they are grounded in solid and extensive local research data. Given the fact that portfolio compositions have undergone significant changes during the past three decades, this article draws on data from the Survey of Family Income & Expenditure in the Taiwan Area of the Republic of China between 1976 and 2004 to examine the changes in the composition and economic characteristics of the household, as well as the characteristics of the economic head of the household, that have occurred during this period in Taiwan. The major research findings are: (1) the increasing percentage of one-generation households; (2) the decrease in the number of children under 18-years of age as the primary cause of the dwindling household size; (3) the increasing percentage of single-person households, childless-couple households, single-parent households, and households with only grandparents and grandchildren; (4) the increasing economic independence of senior citizens; (5) the quantity and quality of the transformations in single-parent households; (6) the deterioration of the economic conditions in households with grandparents and grandchildren only; and (7) the increasing number of working members of nuclear families.
