How many people today show up unannounced at the residence of someone else?

The ring of the doorbell when you’re not expecting anyone is, at the least, odd. Above all in big cities, where distances between homes can be long and the act of going to see someone implies a certain amount of preparation to traverse the town. In far-flung neighborhoods, the chance that someone was merely in the area is low and the sound of someone at the door is more commonly tied to the arrival of a delivery person or a letter carrier. Unexpected visits are getting less common, be they from friends, family members or neighbors who show up unannounced with the aim of having a little chat.
Such encounters happen often in small urban centers and rural areas where neighbors don’t just share walls, but also, in a certain way, their free time. A lack of new residents can lead to deeper personal relationships with one’s existing neighbors that aren’t limited to a simple “hello” and “goodbye,” as they are in larger-sized cities. In contrast, social relationships that develop in the neighborhoods of major metropolises, particularly those groupings of persons who are tied together by nothing more than the simple fact that they share space, are in danger of extinction. Such are the claims of some neighborhood associations that are bearing witness to a massive exodus of local populations, supplanted by temporary neighbors, inhabitants of tourist apartments in which they rent rooms or the entire apartment and spend a short amount of time in the city. Rent increases that have taken place in recent years, added to the impossibility of saving up enough to buy one’s own home, are transforming the urban social balance.
As the article suggests, this is a massive shift from much of human history where people lived in smaller communities and tended to have closer ties with people around them. Today, we are more used to choice in selecting our relationships. Still, we encounter people we do not know regularly, whether that is looking at them from our moving vehicle or in a store or at a public event.
What if the future looks like a Black Mirror episode where people do not have to interact with anyone they do not want to? Or could technology provide us information about people as we pass near them?
