Families are couples with or without children and single parents with children. Children, regardless of their age, are all biological, step- and adopted children living in the same household with both their parents or a single parent and without their own partner or their own children. Thus, parents with adult children also count as a family. Children who have moved out of the parental home are not taken into account. Each family represents a separate unit of analysis, regardless of whether it inhabits a household with other persons or families.
The results refer to the population in private households and come from the Microcensus Labour Force Survey (sample survey) and the Register-based Census / Register-based Labour Market Statistics (administrative data). The publication of the Microcensus Labour Force Survey refers to the previous year, that of the Register-based Census / Register-based Labour Market Statistics to the year before that.
