High Social Mobility Leads to Delayed Reproduction

Many important family decisions, such as when to have offspring, essentially manifest different life history strategies, ranging from slow to fast ones. The current research examined how one critical societal factor, social mobility (i.e., the shift of socioeconomic status in a society), may contribute to such slow (vs. fast) life history strategies. With four multi-method studies, including archival data at the national level, a large-sample survey (N = 6787), and experimental studies (N = 497), we found that a high level of social mobility predicted and resulted in delayed reproduction. Specifically, a high level of social mobility, indexed by both objective reality and subjective perception, predicted individuals’ positive future expectations. This further leads them to focus on long-term goals and foster a slow life history strategy, i.e., preferring delayed reproduction. Theoretical implications are discussed. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
