The 2011 census found 37 percent of private dwellings were home to just one person. It means just over 17 percent of the population lives alone.
More than half the population lives in homes with two or three people, the 2011 census said, though there were more than twice as many two-person households as three-person ones.
And 60.3 percent of households were home to a family. The census clarified that 33 percent of all households were families with children, and 28 percent were childless couples. The division of families into different categories meant single-person homes were Germany’s most common form of household.
And within the group of families with kids, 54 percent had just one child.
Meanwhile, 22 percent of German homes housed pensioners (those over 64) and in around nine percent of households, over-64s and younger people lived together.
Around 95 percent of pensioners lived in private households (including old people's homes) compared with four percent living in other accommodation such as housing communities, according to the census.
