Are Orthodox Jews happier with their marriages than others? Do the demands of taharas ha-mishpachah translate into a better relationship? There now is some evidence of better marriages within the Orthodox community, as reported in the Wall Street Journal:
According to the Aleinu Marital Satisfaction Survey—an anonymous online study conducted by the Orthodox Union in conjunction with a program of Jewish Family Service of Los Angeles and the Rabbinical Council of California—72% of Orthodox men and 74% of Orthodox women rated their marriages as excellent or very good. By contrast, only 63% of men and 60% of women in the public at large told the General Social Survey, conducted by the National Opinion Research Center at the University of Chicago, that they were very happy in their marriages.
