The caveat does help, and I notice the article is better researched and written than it was when I commented two years ago. However, observationally, I do see an ethnic component. My town is a predominantly middle-class suburb of 46,000, with a much higher percentage of blacks, Latinos, and Armenians than the U.S. or state averages. These middle-class families tend to be more multigenerational than white middle-class families; thus, I think it is more acceptable for white middle-class families to be multigenerational here.  03:11, 11 October
