Yung-Han Chang, Health Care Management Department, University of Kang Ning, Taiwan Abstract: Changes of household composition are usually a result of complicated interplay of multiple factors. Among many changes of household composition over the life course, some household compositional changes may be particularly associated with special needs, such as childcare. As childcare is usually arranged informally in Taiwan, this study investigates whether household extension could be a way of obtaining childcare support from relatives. Using data from the Taiwan Social Change Survey, this study aims to reinvestigate the determinants of household composition from the perspective of childcare arrangements. Research results show that after holding mothers’ employment status, demographic and household-context variables constant, the presence of children under age 3 is still significantly associated with household composition. The finding supports the argument that people with young children are more likely to co-reside with elderly parents or extended kin. Although the causal relationship between having childcare needs and living in stem and extended households could not be established, this study provides empirical evidence of the association between childcare needs and household composition.

It changes over time in relation to both structural and individual status. Structurally, the changes in socioeconomic characteristics and cultural patterns may help determine household composition. Individually, insight from family development theory (Rodgers and White 1993) reminds us that a household’s structure changes as people change their living arrangements when they reach different stages of life. Among many changes of living arrangements at life stages, some household changes are particularly associated with special needs, such as childcare. In East Asian societies, many people had the experience of living with their grandparents before entering kindergarten. This strategic living arrangement is deemed as a way to resolve the dilemma of many working mothers and dual-earner families. Nevertheless, however common this temporary arrangement of coresidence may seem to be, it is not without conflicts and negotiations. Changes of household composition are usually a result of complicated interplay of multiple factors. Determinants of Household Composition Household changes could be analyzed in terms of size, number of family members, or structure. Many previous studies have treated household compositional changes as an important element of emerging social issues, including elderly care (Chen 2005; Tseng, Chang, and Chen 2006; Chang and Chang 2010), housing policies (Muller, Gnanasekaran, and Knapp 1999), and female work participation (Lu 1997, 2006). In the last half-century or so, the most influential theoretical arguments on the household have been largely associated with economic resources (Becker and Tomes 1986; Horrell 1994; Gronau 1977). In line with the theory that household composition is the product of economic arrangements, scholars have argued that household composition has changed since the means of production have changed (Kertzer 1991). It is evident that the types of households today are very different from those at the beginning of the twentieth century. One of the popular arguments in favor of household change since twentieth century invokes “nuclearization.” Scholars who support this idea (Goode 1982) contend that as society has become industrialized and urbanized, household size has become smaller. The idea––“nuclearization”––originated among structural-functionalists. Parsons, as the main figure in functionalism, argued in The Social Structure of the Family, that the isolation of the conjugal family (i.e., nuclear family) makes high mobility for workers and work activities possible (Parsons 1949, 263). Family history studies (Laslett and Wall 1975), anthropological (Malinowski 1930; Murdock 1949) and demographic studies (Burch 1970) also offer their explanations of household change (Yang, Li, and Chen 2008). According to Laslett and Wall’s historical study, small families have existed in Europe since the sixteenth century. Anthropological studies Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 345 (Malinowski 1930; Murdock 1949) support their argument. Burch (1970) argues that small families are more common in a society than big families. Although these arguments are taken from different social contexts and timeframes, they have challenged people’s preconceived idea that small or nuclear families follow industrialization. In addition to the arguments above, van de Kaa proposed the Second Demographic Transition theory (SDT-theory) for studying family change (van de Kaa 1987), which argues that family values have been transformed from the earlier bourgeois family model to today’s individualistic family model (Yang, Li, and Chen 2008). What SDT suggests is that today’s individualistic values make families open to a wider range of configurations: living alone, living apart together, living with friends, and sharing house with others (Levin 2004). Unlike societies in the West, the society of Taiwan is rooted in Chinese traditional family values. Generally, a Chinese family is traditionally pictured as a big family. However, Goode found from a survey conducted in 1949 that the average household size in various regions of China is between 4.1 and 6.9 persons (Goode 1982, 98). He suggested that an extended household is always ideal in most societies, but, due to economic pressure and high mortality rates, such an ideal household type is hardly ever achieved. After reviewing the changes of family structures in Taiwan from 1984 to 2005, Yang, Li, and Chen (2008) suggest that the factors which may affect household changes are the mortality rate, fertility rate, and propensity for coresidence (Yang, Li, and Chen 2008, 4). Chen (2004) observed the intergenerational coresidence in rural China and found that cultural norm played a crucial role in living arrangements. Several previous studies in Taiwan (Yang, Li, and Chen 2008; Chien and Yi 2001) also found that household compositional change was associated with people’s attitudinal shift, particularly the propensity to coreside with their elderly parents. Theoretically, the higher the propensity for coresidence between elderly parents and the young adult children, the greater the likelihood that people will live in a stem household (Yang, Li, and Chen 2008, 6). In reality, the propensity for coresidence is constrained and influenced by environmental or objective conditions. For instance, if it costs less to live with children, elderly parents who have few financial resources are likely to choose this option, even when they do not prefer this living arrangement. Similarly, newly married children are likely to live with parents to reduce their expenses. Furthermore, housing capacity, differences between rural and urban locations and the life stage are also important factors associated with household composition (Yang and Zeng 2000; Chang 2010; Chang 2014). In terms of housing capacity, it is argued that people’s decisions on household composition are partially constrained by the options open to them. A previous study comparing the trends in Tianjin and Shanghai (Logan, Bian, and Bian 1998) showed that the traditional household size and intergenerational coresidence persisted when state policies reduce housing Downloaded by [University of Kang Ning] at 01:45 15 October 2015 346 CHINESE SOCIOLOGICAL REVIEW opportunities. Furthermore, the increasing number of houses or apartments that could only accommodate small households may also lead to the increase in nuclear or one-person households (Zeng and Wang 2003; Ren and Treiman 2015). Apart from the arguments above, household composition is sometimes involved with economic strategy when there are young children in the household. According to previous studies (Yu 2001; Chen 2005; Sun 2008), some households with young children in Taiwan tend to make a strategic decision to live with parents in order to have help with childcare. Due to the lack of available and reliable public childcare resources, having relatives as childcare givers has been found to be a common practice in Taiwan (Sun 2008). This common form of informal childcare arrangements distinguishes Taiwan from some East Asian societies with similar cultural backgrounds (e.g., Japan and South Korea). Yu (2001) uses this type of informal childcare arrangement to explain the intergenerational coresidence of elderly parents and married children. Despite the possibility that married couples could obtain childcare support if parents lived nearby, Yu argues that the residential childcare support from elderly parents is one of the exchange resources that derive from the mutual interdependence between elderly parents and married children. The following section turns to reviewing childcare arrangements and intergenerational relations in Taiwan. Childcare Needs and Arrangement As society changes, many previous studies in Taiwan show that with regard to childcare arrangements, which are deemed as the responsibility of the family, there is a conflict between seeking public resources and finding reliable private childcare providers (Wang 2011; Wang and Sun 2003). Although scholars and parents have pledged to increase public spending on childcare, childcare is still mainly shouldered by families due to the delayed development of public childcare policy and the persisting gender roles. However, as the female labor participation rate increases, childcare needs become a problem requiring government intervention. According to Jao and Li (2012), the labor force participation rate of mothers of pre-school aged children increased from 34 to 64 percent between 1983 and 2006. The increase is even greater than that of the labor force participation rate of all women during the same period. Based on the Women’s Marriage, Fertility and Employment Survey, in terms of the childcare arrangement for children under age 3, the percentage of childcare by women (ages 15–49) dropped from 76.96 percent in 1985 to 56.9 percent in 2011 whereas the proportion of childcare by grandparents increased to 33.64 percent in 2011 (Directorate General of Budget Accounting and Statistics 2013). Wang’s study (2011) on childcare policy in Taiwan (2011) indicated that percentages of childcare provided by parents and by public childcare system Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 347 were both declining, whereas the percentage of childcare by babysitters, relatives, and private childcare providers were increasing. However, given the above changes, 45.5 percent of Taiwanese people still think that mothers who stay at home and care for their children is the best childcare arrangement (Ministry of the Interior 2010). This social expectation is reflected in the reality that 95 percent of children under the age of 3 are cared for at home. Most of them are cared for by parents or unpaid relatives (Wang 2011). Apart from social expectations, the financial burden of hiring private childcare providers 0–also leads to high percentage of care by family. According to the 2013 Women’s Marriage, Fertility and Employment Survey, the average monthly cost of private childcare for children under age 3 is US$515 and the average monthly income of women is US$1,083. After understanding that private childcare costs more than half of one’s income, many women would rather leave the labor market and care for their children at home. The conflict between family and work has been an old theme for married women (Aryee 1992; Matsui, Ohsawa, and Onglatco 1995). Many married women in Taiwan face crisis in combining family and career. For those working women in a dilemma, the “socially approved characteristics of femininity (such as nurturing and submissiveness) may often come into conflict with the requirements of a “masculine” managerial role (such as toughness and assertiveness)” (Chou, Fosh, and Foster 2005, 253). Although the above discussions seem to picture a zero sum relationship between working and childbearing for women, the positive correlation between the fertility rate and labor participation in North European countries suggests that women joining the labor market is not the real culprit, but a poor balance between work and family (Wang 2011). In terms of the influence of the working environment on working mothers, previous studies suggested that self-employed women are more likely to arrange time for childcare because they were given higher power and flexibility to adjust their working hours and workplace (Tu 2003). However, Tang (2011) indicates that part-time jobs or jobs with flexible working hours are not common in Taiwan. With the constraints of rigid work schedules, leaving the labor market to become full-time mothers is an option left for many working mothers. Notwithstanding, Yu’s comparative study of Japan and Taiwan suggests that informal childcare arrangements in Taiwan help women remain in the labor market with lower labor force withdrawal rate than their Japanese counterparts. According to Sun (2008), for women in Taiwan, it is not only convenient, but also appropriate and safe to ask elderly parents to care for young children. Her study, which compares the childcare practices in extended and nuclear households, shows that extended households that contain seniors may “mediate the relationship between women’s employment and their time spent Downloaded by [University of Kang Ning] at 01:45 15 October 2015 348 CHINESE SOCIOLOGICAL REVIEW on childcare” and “modify the degree to which husbands adjust their childcare participation in [the] light of their wives’ employment” (Sun 2008, 215). The interdependence between elderly parents and married children, which is demonstrated by financial support or childcare support as described above, has been an important social norm and is a common practice. Scholars have developed several models to explain this intergenerational relationship, including the altruism model, the exchange model, and the insurance model (Silverstein et al. 2002). While the altruism model believes in cooperation and contends that transfers between family members are made to meet their needs, the exchange model and insurance model argue that family members provide resources or support to each other in the hope that of receiving help or support in return. Previous studies found that intergenerational exchanges may vary according to household types and elderly parents’ income. Lin (2007) in her in-depth interviews showed that grandmothers with stable income are less willing to care for grandchildren at home than their counterparts without financial independence. Chen and Lin’s (2011) research indicated those who live with parents exchange more by financial support and household chores than their counterparts who live with siblings or others. Moreover, as society changes, intergenerational support also differs. In a traditional Chinese family, it is common for married sons to stay at home with their elderly parents and take care of them. Nonetheless, in the past ten to twenty years, traditional ways seem to have gradually been replaced by a new practice. Kung and Yi (2001) have reviewed the transformation of eldercare arrangements from the Confucian conception of filial piety to the modernized form and have found that new forms of filial piety have emerged. Monetary support or regular visits have gradually replaced coresidence. A study of the intergenerational relations in urban China (Bian, Logan, and Bian 1998) suggested that parents’ relationships with adult children are not affected by non-coresidence. Children could fulfill their filial obligation by paying regular visits or giving small gifts as a sign of respect even when they do live with elderly parents. The transformation of patriarchy traditional culture is another example. In the 1970 s, parents with young children mostly seek childcare support from paternal relatives. In 1999, it has become common to have maternal relatives provide childcare support (Lin 2007). Although coresidential living arrangements are only one way of intergenerational support exchanges, it is deemed as the most direct approach. By coresidence, children may provide elderly care to elderly parents whereas parents provide financial or childcare support to children (Thornton and Lin 1994). This coresidential living arrangement may help the family smooth consumption and overcome constraints. Observing the coresidence between elderly parents and children in rural China, Chen (2004) argues that the relationship between childcare and coresidential living arrangements may Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 349 be closely related to household strategy. She suggests that living arrangements reflect family needs and that coresidence with elderly parents is not a random choice. In other words, “family needs could have both a direct and an indirect effect on the division of labor, with the latter being mediated through decisions on living arrangements” (Chen 2004, 564). Her argument suggests that coresidential living arrangements are a mechanism by which family needs are satisfied and through which the intergenerational division of labor is put on the map. The emergence of the “generation-skipping” household consisting of grandparents and grandchildren in Ren and Treiman’s (2015) study is an example of the said mechanism. According to Ren and Treiman (2015), due to work demands or housing issues, there is a growing number of parents who could not care for their children and have their children live with elderly parents. Childcare support from elderly parents is thus introduced into the households through coresidential living arrangements. Given the above discussions, the research question of this study is constructed based on the argument that the coresidential living arrangement could be a way of obtaining childcare support. Although many studies have discussed the current situations of childcare arrangements in Taiwan, the relationship between childcare arrangement and household composition is rarely examined. In responding to the lack of research in this area, this study aims to investigate the associations between childcare needs and household composition. To specify, this study asks the question would people with childcare needs be more likely to live with their elderly parents or extended family members to obtain childcare support? Based on the above arguments, the research framework is constructed in Figure 1. Figure 1. Conceptual framework of the determinants of household composition. Downloaded by [University of Kang Ning] at 01:45 15 October 2015 350 CHINESE SOCIOLOGICAL REVIEW Figure 1 summarizes the aforementioned arguments and shows the factors that are associated with household composition. According to the framework, the determinants of household composition include demographic variables (i.e., sex, age, and area), childcare needs (i.e., presence of children under age 3 and employment status of mothers), and household-context variables (i.e., availability of kin, including elderly parents and siblings). As this study aims to investigate the association between childcare needs and household composition, the primary focus is on the effects of the presence of young children. Moreover, given that women are still the primary childcare providers for children under age 3, mothers’ employment status is also included in the model. It is hypothesized that the presence of children under age 3 has a positive relationship with people’s probability of living in stem or extended households because people with young children may seek childcare support by living with their elderly parents or other family members. On the other hand, the presence of elderly parents or extended family members may probably increase the likelihood of people having young children as they are likely to obtain more childcare support from extended family members. The said childcare needs are expected to increase when mothers are working. Mothers’ employment status is presumed to make a difference in childcare needs. Although childcare needs are not represented by one single variable and not directly measured in this study, it is expected that the likelihood of people living in stem or extended households would increase when mothers are working (i.e., employed or self-employed). Demographic variables are also important determinants of household composition according to the literature. It is presumed that men are more likely than women to live in stem or extended households as they are usually expected to be responsible for arranging for healthcare and living of elderly parents. As for age, since people change their household composition at different stages, it is expected that there be a significant relationship between age and household composition. However, the relationship could be “curvilinear” rather than a linear effect, therefore age squared is also included in the model. In terms of area, based on the argument of nuclearization, people who live in a rural area are expected to be more likely to live in stem or extended households than nuclear households, while their urbanized counterparts are more likely to live in nuclear households due to different housing costs in various regions. In addition to demographic variables, as the research focuses on the relationship between household composition and childcare needs, household-context variables are also taken into account. In this study, the availability of family members is essential to the argument that people with young children are more likely to live in stem or extended households. Therefore, household-context variables specifically include the availability of respondents’ parents, respondents’ brothers, and sisters. It is presumed Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 351 that the number of elderly parents alive has a positive relationship with the likelihood of people living in stem or extended households, since people with parents around are more likely to seek childcare support by living with their parents than those whose parents passed away. The number of brothers is presumed to have a negative relationship with the likelihood of people living in stem or extended households whereas the relationship of the number of sisters and household composition is not clear. The aforementioned traditional Chinese family setting expects that a son would coreside with their elderly parents and care for them. In practice, if there were more than one son, as one of the sons takes the coresidence responsibility, other sons are more likely to practice filial piety through financial support or regular visits. Consequently, the number of brothers may have negative relationship with people living in stem or extended households. Data, Variables, and Methods Data Data analyzed in this paper were collected in the third cycle’s second year, fourth cycle’s second year, and sixth cycle’s second year surveys of the research project “Taiwan Social Change Survey.” The project was conducted by the Institute of Sociology, Academia Sinica, and sponsored by the Ministry of Science and Technology, Republic of China. The data were collected through face-to-face interviews of registered non-institutional residents in Taiwan ages 18 or older. (Academia Sinica 2015). The consistency of the datasets is an important advantage for comparisons overtime. As the survey topic varies each year in TSCS, this study adopts the data from 1996, 2001, and 2011 for their suitability. To help the analysis focus on the association between childcare needs and household composition, data of survey respondents from 18 to 50 years old are selected since respondents of this age range are at the life stage of child rearing. Dependent Variable To examine the changes of household composition, household type is used as the dependent variable. In the analysis, household type consists of two categories: (1) nuclear; (2) stem and extended household, which were generated from the four household types: (1) one-person (including households of people living with non-kin), (2) nuclear, (3) stem, and (4) extended. One-person households are excluded from the analysis as they are not related to the research focus in this study. This classification of household is based on Yang, Li, and Chen’s (2008) household types, which is based on the coresidence condition of each family member reported in the TSCS data. In TSCS, there is no variable specifically Downloaded by [University of Kang Ning] at 01:45 15 October 2015 352 CHINESE SOCIOLOGICAL REVIEW indicating in which “household type” that respondents live, household types have to be constructed based on the variables associated with living arrangements. Based on 42–50 variables in the TSCS, which ask whom you live with, Yang et al.’s classification can catch most cases according to the relationships between the respondents and other members in the same household. Table 1 shows the family relationships used in their classification. As we can see, there are two types of kinship: lineal and collateral. And in each type, the relationships are classified as elder, same, and junior generations. In terms of theory, Yang et al.’s classification follows the family study tradition with nuclear, stem, extended households as the core household types. This is theoretically coherent with my research question, which focuses on associations between childcare needs and household composition by comparing the likelihood of people living in nuclear and stem/extended households. Figure 2 summarizes the details of the four household types. In the analysis, one-person households are excluded while stem and extended households are recoded into one category. One-person households include respondents who live alone or with nonrelatives. Nuclear households generally include respondents who live with partners and children. However, single-parent households and households of married couples without children are also categorized as nuclear household in the classification. Stem households include two generation households with married children or elderly parents and three generation households with grandchildren or grandparents. Extended households include two or more collateral partnered relatives. More specifically, the definitions of each household type are as follows: 1. Nuclear: respondents at the age of marriage and childbirth who live with only nuclear family members would be identified as living in the “nuclear” household. Table 1 Relationships of Family Members Relationship Members Lineal Elder1 Elder2 Same generation Junior1 Junior2 Grandparents Parents, parents in law Spouses, partners Children, children- in-law Grandchildren Collateral Elder Same generation Junior Uncle/aunt Siblings, cousins Nephew/niece Other Unspecified kin, friends, others SUMMER 2015 353 Downloaded by [University of Kang Ning] at 01:45 15 October 2015 Figure 2. Four major household types. Note: Please see household composition classification schema from Yang, Li, and Chen (2008). 2. Stem: stem households include two generation households with married children or elderly parents and three generation households with grandchildren or grandparents. 3. Extended: extended households include two or more collateral partnered relatives. Explanatory Variables Explanatory variables include sex, age, age squared, area, presence of young children under age 3, mothers’ employment status, number of available parents, number of brothers, and number of sisters. As sex and age are taken from the original data without recoding, the explanations of these two variables are omitted in this section. Area is generated based on survey respondents’ current residence. In the original data of TSCS, the current residence is coded based on the administrative regions. Population size and population density of each region determines the classification of the region. A total of 358 regions are classified into three categories: cities, towns, and rural area. Household-context variables include the number of available parents, the number of available brothers, and the number of available sisters. The three variables are all constructed based on the household information reported by the respondent. Respondents are asked to answer the questions whether their parents are still alive and how many brothers or sisters they have. In addition, the household information of respondents’ spouse is also provided. The number of available parents is then generated based on the number of Downloaded by [University of Kang Ning] at 01:45 15 October 2015 354 CHINESE SOCIOLOGICAL REVIEW respondents and their spouses’ elderly parents who are still alive. Due to data limits, proximity and health status of elderly parents are not accounted for. The number of brothers and sisters are generated in the same way. Both variables take respondents and their spouses’ brothers and sisters into account as they are also potential childcare providers. Presence of children under age 3 is constructed based on the information of the presence of children and the age of children. According to literature, childcare is specifically deemed as the responsibility of mothers and family before children reach age 3 (Wang and Sun 2003; Wang 2011). Nevertheless, for comparisons, later in the analysis the presence of children under age 6 is also used. In most rounds of TSCS, respondents are asked to report their present employment status and their spouses’. The questions are detailed with regard to sector, salary, previous working experience, workplace, and the respondent’s relationship with their employer. As only a few questionnaires of different years in the TSCS have asked about working hours, it is not available in many years of the survey. Moreover, as part-time jobs are not common in Taiwan, working hours are not taken into account. On the other hand, because the research question is about childcare needs, working mothers as employees or employers may make a difference in childcare arrangement, as employers or the self-employed have higher autonomy to arrange their working hours and make time for childcare. In the same vein, women work for their family business are also expected to be given higher flexibility at work. Therefore, mothers’ employment status is recoded into three categories: employed (i.e., employees working for private companies or government), self-employed (i.e., employers, self-employed/independent workers, or family workers), and unemployed or inactive (i.e., housewives, students, and retirees). Methods Cross-tabulations and logistic regression are adopted to analyze the data. While cross-tabulations are used to explore the relationship between explanatory variables and the outcome variables, binary logistic regression is adopted to examine the effects of childcare needs with other factors being held constant. Descriptive Results from Cross-Tabulations This section examines the relationships between the dependent variable and explanatory variables. For the benefits of understanding the research question with social changes in mind, the changes of household composition and the presence of young children over time from 1996 to 2011 are also explored. The results (not shown here for conserving space) indicate that Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 355 there is a distinct decline in the percentage of presence of young children under age 3 over time. However, the changes of household composition are not clearly indicated by the data collected in three different years. Table 2 shows the percentages of people ages 18–50 in different household types by demographic and household-context variables based on the 1996, 2001, and 2011 datasets from TSCS. The results indicate that men are more likely to live in stem or extended households than women. While people ages 36–50 are less likely to live in stem or extended households than their younger counterparts; city-dwellers are also less likely to live in bigger households than people who live in rural areas. Generally, the associations between demographic variables and household composition are as expected. However, the higher percentage of people ages 36–50 living in stem or extended households as compared to people ages 26–35 is intriguing. As age is related to life stages, childcare needs or a delay in leaving parental home may help explain this result. In terms of the household-context variables, generally people with more parents who are alive and people with more brothers are both more likely to live in nuclear households while the number of sisters does not show clear differences in the distribution of household types. Regarding childcare needs, Table 3 shows that people with children under age 3 are more likely to live in stem or extended households as compared to people without children under age 3. The difference between the percentages of people with children under age 3 living in stem or extended households and people without children under age 3 living in stem or extended households becomes even more evident once mothers’ employment status is taken into account. By selecting the data with mothers’ being employed based on mothers’ employment status, Table 3 also indicates that when mothers are employed, the likelihood of people with young children under age 3 living in stem or extended households is even higher than it is when mothers’ employment status is not considered. The associations between household composition and different employment status of mothers are compared in Figure 3. Figure 3 shows that different employment status of mothers is associated with different probability of people with young children under age 3 living in stem or extended households. By comparing mothers employed, people with young children under age 3 seem to be less likely to live in stem or extended households when children’s mothers are self-employed. To further analyze the relationship between childcare needs and household composition, the data of people without children are excluded. By comparison with all people ages 18–50, Table 3 shows the difference in the percentage of people living in stem or extended households associated with the presence of children under age 3, which decreases by 6.8 and 10 percent, respectively, once people without children are excluded from the analysis. However, in contrast with people with children, people with young 356 CHINESE SOCIOLOGICAL REVIEW Table 2 Characteristics of People Ages 18–50 in Each Household Type (percentage by row) Household type Downloaded by [University of Kang Ning] at 01:45 15 October 2015 Nuclear Stem/Extended N Sex (%) Male 64.9 35.1 1197 Female 67.1 32.9 1738 18–25 64.3 35.7 322 26–35 55.4 44.6 813 36–50 71.4 28.6 1800 City 71.0 29.0 1100 Town 67.0 33.0 1467 Rural area 48.6 51.4 368 0 88.2 11.8 76 1 69.1 30.9 301 2 71.2 28.8 943 3 61.0 39.0 761 4 62.4 37.6 854 0 67.4 32.6 622 1 58.6 41.4 425 2 56.9 43.1 378 3 60.9 39.1 435 4 68.0 32.0 366 5 and more 77.0 23.0 709 0 65.4 34.6 731 1 65.0 35.0 360 2 64.3 35.7 372 3 66.5 33.5 373 4 67.8 32.2 345 5 and more 67.6 32.4 754 Age (%) Area (%) Number of available parents (%) Number of available brothers (%) Number of available sisters (%) (Continued ) SUMMER 2015 357 Table 2 Continued Household type Nuclear Stem/Extended N Downloaded by [University of Kang Ning] at 01:45 15 October 2015 Year 1996 66.1 33.9 1133 2001 69.0 31.0 1048 2011 62.5 37.5 754 Total 1943 922 2935 children under age 3 are still more likely to live in stem or extended households especially when mothers are employed. Multivariate Regression Analysis In this section, logit regression analysis is used to examine the associations between childcare needs and the explanatory factors. The binary outcome variable for household composition contrasts living in stem or extended households with living in nuclear households (stem/extended household ¼ 1, nuclear household ¼ 0). Table 4 shows the results from the models using logit regression. As we can see from the table, all the explanatory variables are entered sequentially according to the modelling design based on research interest. Demographic variables and the presence of young children under age 3 are entered first, and then the employment status of mothers followed by household-context variables. By entering the explanatory factors to the models in this order, it is possible to compare the results from different models in the nested form. In Table 4, Model 1 focuses on the effect of demographic variables and the presence of young children under age 3. Overall the variables in Model 1 show significant effects with household composition. In contrast with nuclear households, people ages 18–50 who live outside of the cities, especially the rural area, are more likely to live in stem or extended households. While age shows a significant positive effect with living in stem or extended households, age squared shows a negative effect. The positive effect of age indicates that as people get old, they are more likely to live in stem or extended households. Nonetheless, the negative effect of age squared suggests a curvilinear relationship between age and household types and shows that after people reach a certain age, they become less likely to live in stem or extended households by comparison with nuclear households. This finding supports the argument that household composition changes with one’s life cycle. People change their household composition from nuclear to other household types when they grow older and change 67.5 52.9 66.2 No child age<3 With child age <3 All 33.8 47.1 32.5 Nuclear Stem/Ext. 2935 257 2678 N 66.2 48.7 67.7 33.8 51.4 32.3 Nuclear Stem/Ext. 1429 111 1318 N 60.3 53.3 61.1 39.7 46.7 38.9 Nuclear Stem/Ext. 2492 257 2235 N Household type of parents ages 18–50 Presence of child age>3 Household type of people Household type of people ages 18–50 with mothers ages 18–50 being employed Household Type Household Types by Presence of Children Under Age 3 (percentage by row) Table 3 57.8 49.6 58.6 Nuclear 42.2 50.5 41.4 Stem/Ext. 1141 111 1030 N Household type of parents ages 18–50 with mothers being employed Downloaded by [University of Kang Ning] at 01:45 15 October 2015 358 SUMMER 2015 359 Downloaded by [University of Kang Ning] at 01:45 15 October 2015 Figure 3.

With the demographic variables (i.e., sex, age, and area) held constant, the presence of children under age 3 shows a significant positive relationship with living in stem or extended households by comparison with nuclear households. This significant relationship persists and even increases when mothers’ employment status is added to the regression analysis in Model 2. In contrast with mothers being employed, when children’s mothers are self-employed or employers, people are more likely to live in stem or extended households than nuclear households. This result contradicts with the prediction based on the preliminary results from cross-tabulations. Based on the cross-tabulations, Figure 3 shows that there is a lower percentage of people with young children under age 3 living in stem or extended households given children’s mothers are self-employed than their counterparts with employed mothers. Accordingly, it is expected that people would be less likely to live in stem or extended households when mothers are selfemployed. However the result in Model 2 shows that when the demographic variables and the presence of children under age 3 are held constant, mothers being employed does not show a significant relationship with people living in stem or extended households, whereas mothers being self-employed has a significant positive relationship with living in stem or extended households. To explain, while self-employed mothers are presumed to have higher autonomy and flexibility at work, the nature of self-employment or family business is probably related to higher likelihood of living in stem 360 CHINESE SOCIOLOGICAL REVIEW Table 4 Logit Regression on Household Composition of People Ages 18–50 (contrast with nuclear) Model 1 Model 2 Model 3 Model 4 Model 5 Sex (Male ¼ ref) 0.216* 0.222* 0.198* 0.197* 0.107* 0.099* 0.101* 0.103* 0.090 0.002** 0.002** 0.002** 0.002** 0.002** Town 0.182* 0.185* 0.246** 0.249** 0.246** Rural area 0.947*** 0.935*** 1.076*** 1.084*** 1.079*** 0.327* 0.325* – Downloaded by [University of Kang Ning] at 01:45 15 October 2015 Female Age Age square 0.198* Area (city ¼ ref) Presence of children ages <3 (no child age <3 ¼ ref) With child age <3 0.381** 0.391** Mothers’ employment status (unemployed/inactive ¼ ref) employed 0.111 0.007 0.008 0.009 Self-employed/ employer 0.356* 0.328** 0.322** 0.321* Number of available parents 0.114** 0.113** 0.114** Number of available brothers 0.128*** 0.120*** 0.121*** 0.016 0.023 0.023 2001 0.113 0.113 2011 0.063 0.056 Number of available sisters Year (1996 ¼ ref) Presence of children ages <6 (no child age <6 ¼ ref) With child age <6 Constant Log likelihood Chi-square 0.193 1.795* 1.740* 1.972* 2.015* 1.807* 1805.5103 1801.3828 1777.5844 1776.3933 1777.2889 143.98 152.23 199.83 202.21 8.32 45.41 2.37 200.42 Model comparison X2 – P value N 0.0156 2,935 2,935 <0.001 2,935 0.305 2,935 2,935 Notes: *p < 0.05; ** p < 0.01; ***p < 0.001. or extended households in contrast with nuclear households. As for mothers being employed, after controlling for demographic variables and the presence of children under age 3, the insignificant correlation between mothers Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 361 being employed and living in stem or extended households by comparison with mothers being unemployed or inactive indicates that the positive relationship shown in Figure 3 could be explained by demographic factors. On the other hand, the comparison between Model 1 and Model 2 seeks to tease out the effects of childcare needs by taking mothers’ employment status into account in Model 2. After controlling for mothers’ employment status, people ages 18–50 with children under age 3 become even more likely to live in stem or extended households instead of nuclear households. Although different employment status of mothers may be associated with different levels of flexibility at work and hence different childcare needs, the presence of young children still shows a significant relationship with higher likelihood of coresiding with elderly parents or extended kin by comparing effects of the presence of young children within the group of the same employment status of mothers. Household-context variables are entered in Model 3. It is presumed that the number of elderly parents alive has a positive relationship with the likelihood of people living in stem or extended households. The significant positive relationship between the number of available parents and living in stem or extended households in Model 3 supports the assumption. While the result with the number of parents is straightforward, the significant negative relationship between the number of brothers and living in stem or extended households is intriguing. As discussed earlier, intergenerational coresidence between sons and elderly parents is expected in a traditional Chinese family. However, if there were more than one son, as one of the sons takes the coresidence responsibility, other sons are more likely to live in separate households and practice filial piety through financial support or visits. Moreover, due to space limits, it is less likely to form extended households with sons, sons’ spouses, and elderly parents under the same roof. Comparisons between Model 2 and Model 3 show that the strength of the effect of the presence of children under age 3 decreases while the effect of mothers being self-employed increases. This implies that the effect of the presence of young children on household composition could be partly explained by the availability of kin. In other words, as the availability of kin varies, the likelihood of people with young children living in stem or extended households changes. This finding is expected as the availability of kin predetermines the possibilities that people could live in stem or extended households. What is noteworthy is that, even after controlling for the number of parents, the number of brothers and sisters, the significant correlations between the presence of children under age 3 and living in stem or extended households still exists. As data used in this study spans fifteen years from 1996 to 2011, Model 4 adds years into the analysis. While all the other explanatory variables are held constant, there is no significant relationship between years and household composition as shown in Model Downloaded by [University of Kang Ning] at 01:45 15 October 2015 362 CHINESE SOCIOLOGICAL REVIEW 4. Although the result here implies that there is no significant changes of the household composition between 1996 to 2011, previous studies in China and Taiwan have generally agreed on a declining trend in three-generations or extended households during the past decades (Ren and Treiman 2015; Chang 2014; Yang, Li, and Chen 2008). The insignificant result may be because the data used in this study only spans fifteen years of time with data taken from three different years within this period. According to the literature, childcare responsibilities are mainly shouldered by mothers or families before children reach age 3 (Wang and Sun 2003, Wang 2011). Previous studies have also indicated that childcare is often arranged differently for children under age 3 and children ages 3–6 (Wang 2011). Therefore, it is argued that seeking childcare support from kin by coresidence could be temporary. After children reach age 3, private childcare providers would fill the need for childcare as parents would accept external care providers as reliable caregivers. To examine this argument, Model 5 is added into the analysis, which replaces the variable “the presence of children under age 3” with “the presence of children under age 6.” The result shows that unlike the presence of children under age 3, the presence of children under age 6 is not significantly correlated with household composition. This helps to further clarify the relationship between childcare needs and household composition in Taiwan. The temporary living arrangement––coresidence with elderly parents or extended family members, is not associated with childcare in general, but care of children under a certain age (i.e., 3). Discussion and Conclusion Generally the presumed relationship of childcare needs and household composition is supported by the results in this study. The distinct association between having children under age 3 and living in stem or extended households shown in Table 3 is also significant in the regression analysis after holding demographic and household-context factors constant. Although this finding could not imply that people with children under age 3 undertake a decision-making process and decide to strategically live with elderly parents or extended family members, it does show that there is an association between childcare needs and household composition. Weather living in stem or extended households is a strategic choice made by people or a usual custom is a question awaiting future studies. On the other hand, in the context of social change, as the size of households in Taiwan is getting smaller (Chang 2014), the finding seems to be paradoxical in a way that it indicates the association between childcare needs and living in stem or extended households while family support declines. Moreover, with the deterioration of family traditions, integrational coresidence may become even less common in the future. Accordingly, the Downloaded by [University of Kang Ning] at 01:45 15 October 2015 SUMMER 2015 363 finding does not seem helpful in terms of providing insights for childcare arrangements in today’s Taiwan. However, I would like to argue that the finding is valuable exactly because intergenerational coresidence declines. Taiwan is not a society with well-developed public childcare system or eldercare system. Traditionally, care is the responsibility of family. As the proportion of traditional households with elderly parents and children living together decreases, many people are worried that people who need care would be left without support. While it is likely true in many cases, this study shows that elderly parents or extended family members are still the potential support that people could turn to even when they are not living together. Elderly parents or extended family members are likely to provide childcare support through temporary living arrangements. The finding of a significant relationship between the presence of children under a certain age (i.e., 3) and living in stem and extended households shows that the coresidence is temporary. Regarding the limitations of this study, one of them is that this study could not really establish the causal relationship between having children under age 3 and living in stem and extended households as cross-sectional data is limited in identifying the timing of events over the life course. Therefore, for future studies of this topic, if longitudinal data is available, it may help understand the relationship of childcare needs and household composition better. Moreover, in-depth interviews with household members may provide information of the decision-making process of childcare arrangements and living arrangements.
