Using census and survey microdata from 69 countries worldwide, in this paper we document levels of intergenerational coresidence over the life course and examine changes in recent decades. We present evidence of a generalized pattern of increase in intergenerational coresidence during the initial decade of this century. This is most evident among people aged 20–30 and, at least in regions such as Europe and North America and in Latin America and the Caribbean, affects women as much or more than it does men. Rates of increase are fastest in Asia (especially among men), robust in Europe and Latin America, and relatively slow in Africa. This shift is occurring in a variety of demographic, economic, and cultural contexts and appears to run counter to expectations that intergenerational coresidence would gradually decline with modernization and cultural change. We discuss the extent to which these results challenge existing interpretations of the role of the family in contemporary society.

全球青年代际同居水平不断上升

使用来自全球 69 个国家的人口普查和调查微观数据，在本文中，我们记录了生命历程中代际同居的水平，并研究了近几十年来的变化。我们提供了在本世纪最初十年中代际同居增加的普遍模式的证据。这在 20-30 岁的人群中最为明显，至少在欧洲和北美以及拉丁美洲和加勒比等地区，对女性的影响与男性一样多，甚至更多。亚洲（尤其是男性）的增长率最快，欧洲和拉丁美洲强劲，而非洲则相对缓慢。这种转变发生在各种人口、经济、和文化背景，似乎与代际同居会随着现代化和文化变革而逐渐减少的预期背道而驰。我们讨论了这些结果在多大程度上挑战了对家庭在当代社会中作用的现有解释。
