The Germans are an eminently gregarious and social people, and all their leisure is combined with and comprehends lager. The Atlantic is the most cosmopolitan place of entertainment in the City; for, though the greater part of its patrons are Germans, every other nationality is represented there. While journalists and early sociologists both studied the matters, the series of studies initiated by Robert Park at the University of Chicago was the first systematic research program into social worlds as located in symbolic space. Sociologists have long recognized a correlation between urbanization and the development of voluntary associations. The resulting studies, and others carried out since that era, illuminate—whether explicitly or implicitly—the urban perspectives dominant in various social worlds. Sometimes conceptions of social class are salient, sometimes rurality appears in full force, sometimes the city's impersonality and anomie, or the city as a great place for fun, seems to pervade a world.
