Romantic couples with a large age gap often raise eyebrows. Studies have found partners with more than a ten-year gap in age experience social disapproval. But when it comes to our own relationships, both men and women prefer someone their own age, but are open to someone 10-15 years their junior or senior.
While there is variation across cultures in the size of the difference in age-gap couples, all cultures demonstrate the age-gap couple phenomenon. In some non-Western countries, the average age gap is much larger than in Western countries. For example, in some African countries about 30% of unions reflect a large age gap.
