Time series on living arrangements reveal clear signs of demographic transition processes. In 1971, 5.4% of men and 12.1% of women were living alone in private households. In 2020, already 15.8% of men and 18.5% of women were living alone. In contrast, the share of persons in married unions with children sharply decreased (1971: men 30.4%, women 27.3%; 2020: men 21.4%, women 20.8%). This decrease was partly compensated by an increasing number of non-married, cohabiting couples with children.
Living arrangements change over the course of a lifetime and also differ significantly between the sexes. From the age of 20, the realities of men's and women's lives diverge: While more than two-thirds (68.8%) of sons aged 20 to 24 still live with their parents, only 57.8% of daughters at this age still live in their parents' household. In the 25- to 29-year-old age group, three out of ten women (29.7%) already live with children, compared to only one in seven men (14.3%).
From the age of 30, both men and women live predominantly in families
with a partner and children. While this remains the case for men up to the age
group of 55
Relative to the total population, only a very small proportion of people live in institutional households (2018: 1.6%). However, the proportion of people in institutional households increases sharply in old age groups, especially among women. In addition to the results of the Population Censuses, results of the Register-Based Census on the population in institutional households, broken down by age, gender and type of institution, have been available since 2011.
