The suburbs became very popular during the 1950s because of post WWII economic prosperity as well as other factors. American cities were viewed as decaying, there were racial fears that led to a phenomenon called "white flight" of whites moving from cities to the suburbs because of racial fear, and also there was affordable housing to be found in the suburbs that provided more space and luxury for the average American family.
