The Our World in Data team had a fascinating chart visualising who we spend time with, by age.
Summary of the research reads as follows:
Who we spend time with evolves across our lifetimes. In adolescence we spend the most time with our parents, siblings, and friends; as we enter adulthood we spend more time with our co-workers, partners, and children; and in our later years we spend an increasing amount of time alone. But this doesn’t necessarily mean we are lonely; rather, it helps reveal the complex nature of social connections and their impact on our well-being.
While the data is from Americans, I suspect some of these patterns hold in various places around the world.
This chart struck me as the single best argument made for the importance of self-compassion.
Be kind to yourself, you are going to spend many hours with yourself as you grow older.
