The sample of the study included 300 migrant couples selected randomly from among all couples who were living in Jam city at the time of research. Research findings indicated that most of the families were young with an average age difference of 7 years. A considerable percentage of them (around 40 percent) had kinship relationship. Most the families came from Bousher province. The main problems of these families, as indicated by the survey, related to welfare and educational facilities. The main assets of the region, from the respondents' viewpoint were security and being together as a family.Study findings also indicated that martial satisfaction of native people, housewives, safe people, couples with kinship relations and arbitrary migrants was more than that of couples in other categories. Regression analysis, further, revealed that interference from their families, sex, joint entertainment facilities, educational level, mental health, relationship with their families, age and friendship groups, in order of level of effect, had substantial impact on marital satisfaction. They, altogether, accounted for around 47 percent of the variation of the dependent variable.
