Singles worldwide - Statistics & FactsIn industrialized countries, the share of singles has been rising over the last decades. This phenomenon can be observed in geographically and culturally diverse countries such as the United States, France, and Japan. In Japan, for instance, changing demographics have led to the emergence of a real "single culture", dubbed the ohitorisama movement in Japanese. Not everyone is affected by this shift though: as of 2019, Hindus and Muslims around the world were the least likely to live in households where just one adult was present.
