This is likely exacerbated by the trends towards single family homes. A few generations ago, when you lived together with aunts, uncles, cousins, nieces, nephews, brothers, sisters, parents, grand parents, great grand parents, there's always someone to interact with. But nowadays, if your spouse is at work and your children are at school or some activity, there's nobody around. The situation is even worse when you are single. I think the trend of loneliness will increase due to technology unless the stigma in current society of living with your family goes away, but I'm not holding out much hope for that.
