Changes in Family Structure during Shantytown Redevelopment and Their Correlation with the Living Space

Abstract

Amid rapid urbanization, shantytown redevelopment profoundly transforms urban environments and catalyzes substantial changes in social, economic, and family structures. Yet, most previous studies have focused narrowly on the outcomes of single residential mobility events, overlooking the complex dynamics that unfold across the pre-redevelopment, during-redevelopment, and post-redevelopment phases. This study investigates changes in family structure and their correlation with living space throughout all three phases of shantytown redevelopment in Heze City, Shandong Province, China, from 2016 to 2023. Collecting data through a community survey, we gathered 1035 valid responses to analyze family structure and residential characteristics. Our analysis, which included Sankey diagrams and cross-lagged panel models (CLPM), revealed a predominant trend of large families fragmenting into smaller nuclear units and demonstrated a significant positive correlation between family structure complexity (FSC) and living space. Notably, the FSC from a previous phase had a significant influence on the living space of the following phase, indicating lagged effects where housing choices are influenced by prior family structure. Further comparisons across different housing types and tenures during the temporary phase highlighted diverse structural changes among families. These insights are crucial for policymakers to refine urban redevelopment strategies, better meet residents’ needs, and enhance the efficacy of policies.
