Among these four divisions, New England had a significantly higher proportion (84%) of two or more stories homes. New home started with two or more stories in the Middle Atlantic, South Atlantic and Pacific were 76%, 56% and 64%.

In the Midwest (East North Central and West North Central), 57% of new homes started were one story, while the shares in the East South Central and West South Central were 55% and 60%.
