Starting the ’70s, with divorce on the rise, social psychologists got into the mix.

For African American women, the marriage rate increases with age compared to White Americans who follow the same trends but marry at younger ages than African Americans. [69] One study found that the average age of marriage for black women with a high school degree was 21.8 years compared to 20.8 years for white women. [69]
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
