摘要
自二十世纪中叶以来，单人家庭的增加是西方社会最重要的社会人口现象之一。在家庭传统上在决定生活安排方面起着重要作用的社会中，这是一种特别令人感兴趣的现象。在西班牙，1991年独居的人口仅占4.1％，而目前这一比例超过10％，大约四分之一的家庭是单人家庭。这项研究分析了这些家庭的代换过程，并考虑了四个社会人口统计学变量：年龄，性别，婚姻状况和受教育程度。这些变量的影响以及劳动状况，1991年至2011年期间，通过应用人口统计分析和多元Logistic回归模型对西班牙国家统计局的微数据样本进行普查，对独居生活进行了研究。结果表明，过去三十年来，跨年龄段的独居生活增加了，影响了所有年龄段，而且西班牙居民的人口统计学特征也发生了变化。在经济衰退期间，这一趋势并未中断，尽管被雇用增加了人们独自生活的可能性。导致男人单独生活的可能性增加的其他因素是男人和受教育程度较高（尤其是女性）。我们发现这些家庭的社会学特征发生了显着变化：年轻人单身者的相对体重增加，而丧偶者的体重下降，有利于单身。在西班牙经历了社会变革的背景下讨论了这些结果
ABSTRACT
The rise in one-person households is one of the most significant sociodemographic phenomena Western societies have undergone since the mid-twentieth century. It is a phenomenon of particular interest in societies where family has traditionally held an important role in determining living arrangements. In Spain, only 4.1% of the population lived alone in 1991 while currently such percentage is more than 10% and approximately one in four homes are one-person households. This study analyses the process of generational replacement of these households taking into consideration four sociodemographic variables: age, sex, marital status and level of education. The influence of these variables, together with labour status, on solo-living is examined between 1991 and 2011 by applying demographic analysis and multivariate logistic regression models to census microdata samples from the Spanish National Institute of Statistics. Results show an inter-generational increase in solo living, affecting all age groups, as well as a diversification of the demographic profile of solo dwellers in Spain over the last three decades. This trend did not interrupt during the economic recession although being employed increased the probability of living alone invariably. Other factors contributing to a higher probability of living alone were being man and having higher education level (particularly among women). We find notable changes in the sociological profile of these households: an increase in the relative weight of young solo-dwellers and a drop in the weight of widowhood in favour of singlehood. These results are discussed in the context of the social changes that Spain has undergone
