Consanguineous Marriages in the American Population

"Consanguineous Marriages in the American Population" by George B. Louis Arner is a study from the early 1900s examining marriages between relatives in America and how they affect society. The book looks at how common these marriages were, what effects they had, and what people thought about them, using statistical data and social reasons. The study starts by explaining that it wants to show information about these marriages and how they affect the health of children. Arner points out that not enough good data exists from previous studies, so he used information from family history records. He argues that governments should do more to collect data to better understand these marriages and their outcomes in things like reproduction and how the public views them, and through examples from smaller communities, Arner is trying to begin a complete look at this important social and scientific topic.
