居住選擇涉及成年生活的多重層面,而隨著社會變遷,成年人的發展歷程漸偏離傳統路徑,但過往臺灣少有研究從動態視角追蹤檢視青壯年人口的居住轉換。部分研究雖觸及居住安排及房屋所有權的轉變,但研究的對象年齡限於26歲以下或是35歲以上,較少涵蓋30歲前後的居住變化。本研究使用華人家庭動態資料庫,以年齡介於27-39歲之2003年主樣本為研究對象,採用序列分析,追蹤2003至2016年間,三世代樣本(1964-1967、1968-1972、1973-1976)的居住轉換。研究發現不同世代樣本的居住轉換路徑分歧,其中1973-1976世代出現留巢及離巢後返回之路徑軌跡;另一方面,該世代樣本在30歲左右時,在家戶組成及居所類別上皆出現變化,意味著即使三十而立不一定能達到,30歲在居住轉換上仍具有指標意義。
Housing choices are related to multiple aspects of adult life. Whereas young adults' transition to full adulthood has gradually deviated from the traditional track along with social changes, the dynamics of housing transition have rarely been investigated in Taiwan. Although some studies examined the changes of living arrangements and housing tenure of the population aged under 26 or above 35, not many studies looked into the housing changes of those aged around 30. This study used data from the Panel Study of Family Dynamics and adopted the main respondents (ages 27-39) interviewed since 2003 as the sample. By dividing the sample into three cohorts (1964-1967, 1968-1972, 1973-1976), the analysis of housing transitions between 2003 and 2016 was conducted with sequence analysis. Research results showed that there were distinct differences in housing trajectories among different cohorts. Trajectories of staying at or returning to the parental home after leaving were found among the 1973-1976 cohort. Moreover, based on analysis of the long-term trajectories, changes of household composition and housing tenure tended to surge around age 30. This finding implies that age 30 is still the critical age of housing transitions, even though "independence at the age of thirty" may be hard to achieve.
