This is more complex than you might thing. First, there's far more places to meet people - rather than having them over for coffee, we meet in a coffeeshop. Networks have provided a "together in time" alternative to "together in place", so people can game, talk, ... via voice and video rather than traveling to a common location. There's far more 2-working-member families than previously, so the ability to organize household events is reduced. Finally, there's far more organized sports activities that consume both child and parent time. These pull everybody out of the house.
