Dating at age 15
In all 37 cultures it was found that males preferred females younger than themselves and females preferred males older than themselves.These age preferences were confirmed in marriage records with males marrying females younger than them and vice versa.Another study also showed a higher divorce rate as the age difference rose for when either the woman was older or the man was older.In August 2010, Michael Dunn of the University of Wales Institute, Cardiff completed and released the results of a study on age disparity in dating.
A British psychological study published in Evolution and Human Behavior in 2010 concluded that men and women, in general, continued to follow traditional gender roles when searching for mates.
One of the concerns of relationships with age disparities in some cultures is a perceived difference between people of different age ranges.
These differences may be sexual, financial or social in nature. Socially, a society with a difference in wealth distribution between older and younger people may affect the dynamics of the relationship.
There are also social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.
Age-disparity relationships have been documented for most of recorded history and have been regarded with a wide range of attitudes dependent on sociocultural norms and legal systems. Relationships with age disparity of all kinds have been observed with both men and women as the older or younger partner.
