男女不平等在家庭内外都很普遍。一个促成因素可能是一种性别在婚姻中的分散，这在与群体的关系中建立了性别特异性差异。在这里，我们利用生态多样性和不同的社会结构，在中国西南地区发现性别偏见的分散对性别分工的不平等的作用。我们使用可穿戴健身跟踪器和验证读数，确认参与者的每日“步数”与高能量活动（如农业和畜牧业工作）的时间呈正相关，与低能量活动（如休闲和放松）呈负相关。我们采用多层次比较的方法来研究不同分散状态下的性别之间的相对工作负荷模式。我们的研究结果揭示了两个特点，导致一个不利的分工工作量：女性和分散在婚姻。这与以下假设是一致的，即男性留在纳塔尔时，讨价还价的能力有所增加，从而导致工作量的不平等。
Inequality between the sexes is pervasive both outside and inside the home. One contributing factor could be the dispersal of one sex at marriage that sets up sex-specific differences in relatedness to the group. Here we exploit the ecological diversity and different social structures found in southwest China to investigate the role of sex-biased dispersal on inequality in the sexual division of labor. We use a wearable fitness tracker and validated readings by confirming that participants' daily "steps"were positively correlated with time spent in high-energy activities, such as agriculture and animal husbandry work, and negatively correlated with low-energy activities, such as leisure and relaxation. We applied multilevel comparative approaches to examine the relative workload pattern between the sexes under different dispersal states. Our results reveal two characteristics that lead to an unfavorable division of workload: being female and dispersing at marriage. This is consistent with the hypothesis that males have increased bargaining power when remaining in their natal home, leading to inequality in workload.
