People With a Similar Risk of Divorce are More Likely to Marry Each Other

A study by the Max Planck Institute for Demographic Research (MPIDR) and the Norwegian Institute of Public Health found that spouses tend to be very similar in terms of their risk of separation. Marriage is shaped not only by a person's own background, but also by that of their partner. The analysis of over 350,000 Norwegian marriages reveals a previously underestimated phenomenon: people with a similar risk of divorce tend to marry one another.
