What is it about?
Using one million Chinese pregnancies from pre-pregnancy checkup exams, we provide the first documentation of strong and robust evidence of assortative mating by ABO blood type. Compared to random matching, individuals are 5-18% more likely to marry partners with the same blood type (see Table 1 in the paper). The pattern remains when we control for socioeconomic variables such as education, region, and behavior.

Why is it important?
Assortative mating on blood type could have implications for organ transplants, for example.
