Based on the data from the China Longitudinal Ageing Social Survey conducted in 2016,using Latent Class Analysis,this study analyzes the urban-rural differences in the types of intergenerational relations from a whole family perspective.Results show that the common characteristics of the three types of intergenerational relations (tight-knit,support but distant,and detached) from the perspective of whole family are that children have provided their parents with high-frequency financial and emotional support,and the increasing space barrier between generations contributes to the formation of “support but distant” type and “detached” type.The relationship types have significant urban-rural differences with urban areas dominated by the type of tight-knit,and rural areas dominated by the type of support but distant.The results of the analysis on the determinant factors of intergenerational relationship types show that,in both urban and rural areas,the oldest old are more likely to form the tight-knit structure with their children,older adults with chronic diseases are more likely to go into support but distant type with their children,the disabled and widowed older adults are less likely to become detached from their children,and the possibility of family becoming the tight-knit type is quite low in terms of older adults with more number of sons and daughters.Moreover,older adults’ ownership of independent housing increases the possibility of urban families becoming the type of tight-knit,but reduces the possibility of rural families being such type.
