One of the "normalization" phrases was that facilities should "harmonize with housing in the neighboring community. The number of residents should not exceed the number that can be assimilated by the general community services."
From this, one might expect very small residences in typical housing. This was not the case, however.
Denmark recommended a maximum of 300 children and 300 adults, either in separate or combined facilities.
Sweden advocated for "central institutions" of at least 100 and no more than 300.
The President's Committee recommended that institutions be no larger than 500.
