In the USA, there are a number of factors which lead to marriage stability. One is education - high school dropouts have a high divorce rate, college graduates have a lower divorce rate. Another is age at marriage - people who marry before the age of 23 tend to have a higher divorce rate than those who marry at or after 23. Income factors in as well - those with a good income tend to have more stable marriages ( https://www.bls.gov/opub/mlr/2013/article/marriage-and-divorce-patterns-by-gender-race-and-educational-attainment.htm https://www.bls.gov/opub/mlr/2013/article/marriage-and-divor... ). In terms of premarital sexual partners, the given chart shows divorce rates after five years of marriage. It doesn't tell me much - I would think if one were going to divorce, the best time to do so would be within the first few years, before having children. There are many studies of divorce rates after 15 or 20 years, that is what I would be curious to see.
