The study also discovered that from 1650 to 1850, the average person was a fourth cousin to their spouse. In 1950, the average person was the seventh cousin to their spouse. The research believes today, humans are 10th to 12th cousins away from each other.

Many states began to ban cousin marriages after the Civil War. In 2018, 24 states have continued the cousin marriage ban but there are still at least 20 states where the ban does not exist.
