This is probably true, think of when more rural areas had thriving popluations. They aren't near a stadium or amusement park, a family's social life involved their church and "family outings" were organized by church groups. Populations grew around urban areas which have tons of churches in the US but also the opportunity to interact with many more types of people and an explosion of new types of activities. I think Big Outing also made sure sitcom characters went to major league sports stadiums and amusement parks which people aspire to attain.
