The housing shortage in big cities is enormous because the conditions are not right: most properties are far too big for the number of their residents.
One number sums up the local housing problem better than any other: 73 percent. That is the proportion of one- and two-person households in this country. In plain language: almost three quarters of the homes are home to a maximum of two people – either as a couple or as an adult with a child. The typical household is therefore quite small.
Only one in four apartments has more than two people living in it. The proportion of traditional families (two parents, two children) is only nine percent. At least, that is what the new census of the Federal Statistical Office shows.
