Age difference in relationships
Age difference between partners is a social phenomenon and describes the sometimes relatively large differences in age between two partners in a relationship. It is the subject of numerous publications and scientific studies.
The acceptance of larger age differences in love relationships is influenced by social and economic conditions. There have been different views over the centuries and it differs in other cultures regarding the partnerships that are practiced, the type and course of the relationship. For example, there can be a marriage, concubinage and harem. Examples of relationship types are monogamy or polygamy, and the course of a relationship may include divorce, adultery or affair.
Several studies have shown that men and women in different age groups are most attractive. For example, women in their early to mid-twenties are considered particularly attractive, while men reach their peak of attractiveness between the ages of their mid-thirties and early forties. So, on average, there is a difference of 13 years between the both in terms of greatest attractiveness.
"Half-your-age-plus-seven" rule
As a rule of thumb for a socially accepted age difference in relationships, the half-of-age-plus-seven rule is sometimes used, which may have French origins.
The rule used to have a different interpretation than it does today, when it was understood as a formula for calculating a bride's ideal age, rather than a socially accepted lower limit of a woman when dating.
The half-age-plus-seven rule appears in the 1903 book The Little Shepherd of Kingdom Come and the 1965 The Autobiography of Malcolm X.
According to this rule, a 28-year-old would date no one younger than 21 (half of 28, plus 7) and a 50-year-old would date no one younger than 32 (half of 50, plus 7).
