Although it is not dominated by retirees and families with young children, it does have its fair share of both. My neighborhood is dominated by military retirees and families. Most families here are introverts and only interact when they run into each other. Some interaction can be seen at the Little League games and at the parks where they incidentally meet. To gain information, one would accidentally run into one of the residents and discuss business.
Conversation circles about weather, who won the game, the newest restaurant, broad topics.
Issues of politics or religion are not typical conversation. Sometimes during the holidays, people become extroverts and share treats. We never hear of any civic meetings. Then, and only then, will we talk to each other. If we see someone out smoking, we'll talk to them.
