Here in Belgium there's a village that's famous for doing this. Currently there's about 100 people there who are living with another family. https://nl.wikipedia.org/wiki/Gezinsverpleging_(Geel) If you translate you can read about it.

Since you're from the "local" area (Belgium), do you happen to know why the numbers have declined over the years? From this article [1] it seemed like it was hugely popular pre-WWII (3,750) with that article quoting 500 in the modern era.

Less acceptable currently, other alternatives? Still seems famous and popular, just not quite as much as it used to be.
