In 1960, one in eight American households was a single person; today it is nearly one in three, some 38.1 million homes. The loneliness the headlines promised did not follow: US daily loneliness peaked at 25 percent in March 2021 and settled back to around 20 percent by late 2024, and Scandinavia, where close to half of all households are one person, is where people are most likely to say they have someone to count on. Living alone, being isolated, and feeling lonely are three different conditions, as Klinenberg put it, "nothing is lonelier than living with the wrong person." The real risk sits in a smaller group, mostly old, often male, sometimes broke. Sort them out from the 38 million, most of whom are doing fine, and you can actually help them.
