1) What are the population factors behind the growth of the suburbs? We have seen no massive outflux of inner city families into the suburbs. Nor have we seen a massive increase in the nation's home ownership rate since 1997 (perhaps 2-3%) Hence, who are the people buying these new houses in the housing boom?

Your premise is incorrect. Innercity families are moving to the suburbs. In the case of African Americans in the Phila region, at lot of suburbs are increasingly Black. It tends to be more middle class Black families.
Economics and quality of living issues.
A lot of income and race, but both are changing.
