According to one writer, conservatives are 15% more likely to be married than liberals, and after controlling for race, age, sex, income, and education, conservatives are still 11% more likely to be married.1
Despite certain variables being controlled (age because people tend to become more conservative as they get older; income because marriage is higher for incomes above a certain level; etc.), it is still unclear why this difference between marriage rates exists. After all, marriage is highest among the university-educated in America,2 which tends to be liberal-leaning.
Many people who report never being married claimed that they never found the right partner or were not chosen. We don’t know if this is caused by a lack of desire, nor can we rule it out.
Conformity vs. Servility vs. Privacy
