本研究利用2016年華人家庭動態資料庫(Panel Study of Family Dynamics，PSFD) 問卷資料以及2016年各縣市房價所得比分析台灣(不含離島地區)的成年子女與父母同住的因素。以不同婚姻狀態的子女樣本為區分依據，本研究進行以下三種logit 模型: 子女與自己父母同住模型(包含已婚和未婚)、未婚子女與自己父母同住模型、夫妻與先生父母同住模型，並同時在這三種模型中加入居住在城市變數以及房價所得比。
本研究發現在三種模型中教育程度相關變數、父母或是先生父母擁有住宅所有權、以及未婚子女或是夫妻居住在城市等變數對於代間同住皆有顯著性。教育程度越高的成年子女，通常有可在外獨立生活的能力，因此對自我的居住安排有較強的支配力，其通常選擇離開父母家中自立門戶以保有隱私性的個人生活。父母或是先生父母擁有住宅所有權，以交換理論中的資源論解釋，當父母有住宅所有權時，相當於父母握有較多資源，代表其在親子居住安排關係中擁有較大權力，自然可吸引或是要求子女與其同住。未婚子女或是夫妻居住在城市(直轄市、縣轄市等地區)則較不會與父母或是先生父母同住。過往文獻指出居住都市地區的子女若是出身自鄉下地區，去往都市就業因而定居，故無法與在鄉下的父母同住。此外，未婚子女年齡、未婚子女從業身分、父母親其中一方健康不佳等變數對未婚子女與自己父母同住模型亦具顯著性；先生年齡、妻子年齡、妻子月收入、先生弟弟數目、夫妻有小孩、先生父母有幫忙照顧小孩等變數亦對夫妻與先生父母有顯著效果。在本研究中，房價所得比變數對於成年子女與父母同住並無顯著影響。

This study analyzes the factors of adult children living with their parents in Taiwan by using the 2016 Panel Study of Family Dynamics (PSFD) data and the 2016 house price to income ratio by counties.
The study finds that education-related variables, home ownership by parents or by husband's parents, and unmarried children or couples living in the urban areas were significant for intergenerational coresidence. Adult children with higher educational attainment usually have the ability to live independently outside the home and have more control over their own living arrangements. Therefore, they often choose to leave their parents' home to live on their own in privacy. When a parent or husband's parents have ownership of a home, which means they have more power in the parent-child living arrangement and can attract or require their children to live with them. Unmarried children or couples living in the urban areas are less likely to live with their parents or husband's parents. The literature indicates that children who live in urban areas are not able to live with their parents in rural areas if they are from rural areas and go to urban areas to work and settle. In addition to the above variables, the variables of unmarried child's age, unmarried child's employment status, and one parent's poor health are also significant in the unmarried child-parent coresidence model of this study.
In this study, there is no significant effect of the house price to income ratio on adult children living with their parents.
