The Pew study shows similar results; it found that 71 percent of the LDS sample were married; only 9 percent were divorced or separated. Twelve percent had never married and 5 percent were widowed. The 71 percent was the second highest percentage of all the groups. Hindus were higher (78 percent) but that figure likely reflects the immigration of Hindu families together.
