The San Francisco study found that the migrants were half as likely to be separated, divorced, or widowed as the blacks they encountered upon arrival. Overall, wherever they went, they tended to be “more family-stable compared both to those they left behind at their origin and those they encountered at their destination,” the sociologist Thomas Wilson wrote in 2001. “They are less likely to bear children outside of marriage and less likely to be divorced or separated from their spouses.”
