Earlier this week, sociologist Herbert Gans passed away. From what I have read of postwar sociology studies of the growing American suburbs, I would place his 1967 book The Levittowners at the top of the list:

Similarly, Dr. Gans challenged conventional wisdom about postwar suburbia in “The Levittowners” (1967). For more than two years, he lived in Levittown, N.J., later renamed Willingboro, and concluded that the residents had strong social, economic and political commitments, and that notions of suburbanites as conformist, anxious, bored, cultureless, insecure social climbers were wrong.
Here is my summary of the book in the Oxford Bibliographies entry on “Suburbanism”:
Gans moved into one of Levittowns, located in New Jersey, in its infancy and lived there for several years. The book challenged several critiques of mass produced suburbs including homogeneity, blandness, and that suburbs damaged families and individuals. However, Gans suggested Levittown had its own problems including limited activities and space for teenagers, ongoing conflict, difficulty engaging with pluralism, and unresolved tensions between private home life and community structures.
For example, here is what Gans concluded about what shaped the community in the new suburb:
Perhaps the most significant fact about the origin of a new community is that it is not new at all, but only a new physical site on which people develop conventional institutions with traditional programs. New towns are ultimately old communities on new land, culturally not significantly different from suburban subdivisions and urban neighborhoods inhabited by the same kinds of people, and politically much like other small American towns.

On this point, he thought the Levittowners showed similar characteristics to what De Toqueville found in American civil society.
At the same time, he expressed critiques of the new suburban life. Here are my notes from pages 431-432 about his recommendations: “(1) most important priority for future suburban planning is the population mix (2) suburbia must be made available to all who can and want to come – especially made available to poor and nonwhite families (3) communities should be planned with block homogeneity and community heterogeneity.”
Many others have studied suburban life and communities but this thorough study set a high bar.
