Satisfaction with marriage shows the subjective assessment of each individual on the quality of his/her marriage. The sampling survey was conducted once in a transect across 1,819 household representatives from 9 communes / wards in 7 provinces / cities across the country, of which men accounted for 48%. The sample has an average age of 44.6 years, a standard deviation of 11 years. Marriage satisfaction in general and its 6 aspects (husband and wife affection, consensus / understanding between husband and wife, sex life, material life, husband / wife's family work and personality / Behavior of spouse) is assessed on 11 steps from 0 (very unhappy) to 10 (very satisfied). Social demographic information of individuals and households is also collected. Research results show that, in general, the research object is quite satisfied with his marriage (GPA = 8.2) as well as with the aspects of marriage (GPA ranges from 7.58 to 8.37). Marital affection with husband and wife has the strongest predictability for satisfaction with marriage in general.
