Historians D'Emilio and Freedman put the beginning of casual sex, including college hookups, further back in history, to the early 1800s, and explain the phenomenon as shaped by historical and cultural forces.

They give as examples planter class white men who had casual sex with enslaved African American women, and white male college students who had casual sex with both white and black women.

For example, a study of Canadian college students who planned to hook up while on spring break showed that 61% of men and 34% of women had sex within a day of meeting their partner.

Another study was based on a survey of over 18,000 college students from ages 18–25.

Freitas' study has found that students on these campuses generally feel that the decision about whether or not to be in a relationship is out of their control and that "hookup culture dictated for them that there would be no dating and that they simply had to endure this reality." Oftentimes, men and women seem to not be on the "same page." According to Bogle, many males believed that females often invested themselves or had an ulterior motive for pursuing a hookup like situation.

For instance, when a male student was asked if he felt that women looked for different components in a hookup; his response was that most females generally did not lean towards a "one and done" thing.Today, according to one study the vast majority, more than 90% of American college students say their campus is characterized by a hookup culture, Nationally, women now outnumber men in college enrollment by 4 to 3, leading some researchers to argue that the gender imbalance fosters a culture of hooking up because men, as the minority and limiting factor, hold more power in the sexual marketplace and use it to pursue their preference of casual sex over long-term relationships.One study has found that the strongest predictor of hookup behavior was previous experience hooking up.People are marrying and beginning families at ages later than previous generations while becoming sexually mature at an earlier age.As a result, Garcia and other scholars argue that young adults are able to reproduce physiologically but are not psychologically or socially ready to 'settle down' and begin a family.Young women tend to be honest about their sexual encounters and experiences, while young men tend to lie more often about theirs.
