That is how much they spend for housing. That includes all those things mentioned both in 1950 and in 2004.
The costs are per household not per family. Single parent, single person and families all count.

I suspect that you mean the Dept. of Labor. And you can cherry pick or invent any figures you like. If you dispute the examples that I myself provided, then that's something different.
