This article is an analysis of the frequency and characteristics of unrelated individuals between 1900 and 1950. The much-heralded rise of the primary individual during the 20th century has been offset by a decline in the frequency of secondary individuals. The overall percentage of persons residing without family did not exceed turn-of-the-century levels until the 1970s. Using data from national microdata samples of the census for 1900, 1940, and 1950, the study applies decomposition techniques and life-course analysis to investigate these patterns. The results show that the decline of the secondary individual from 1900 to 1950 was largely a function of changing demographic composition, but the increase of primary individuals is linked to changing residential preferences.
本文是对1900年至1950年间非亲属个体的频率和特征的分析。20世纪备受瞩目的主要个体的增加，被次要个体频率的下降所抵消。直到20世纪70年代，没有家人同住的人的总体比例才超过世纪之交的水平。该研究利用1900年、1940年和1950年全国人口普查微观数据样本的数据，应用分解技术和生命历程分析来研究这些模式。结果表明，1900年至1950年间次要个体的减少主要是人口构成变化的结果，但主要个体的增加与居住偏好的变化有关。
