Friendship is one of the most important things in life for our happiness and well-being. Yet, people today have fewer friends than ever. One survey found that the number of adult Americans who reported having no friends went from 3% in 1990 to 12% in 2021. Another study found that Americans went from spending on average seven hours a week with their friends in 2003 to only spending less than 3 hours a week with their friends by 2021.
