The present research is descriptive co-relational survey and of purposeful purpose. The statistical population of the present study was all students of the Humanities Department of Science and Research Branch, Islamic Azad University, Tehran whose number was 288. The number of samples was 143 who randomly selected based on the Morgan table. Data were collected from two researcher-made questionnaires: 1-social factors (family attitude, friendship, education, economic status) including 41 questions and 2-cultural factors (religion, customs, traditions, beliefs and beliefs) which included 33 questions based on the five-value Likert spectrum used in this study. Findings of the research indicated that the components of religion and religion, customs, traditions, beliefs and beliefs, family attitudes, friends' attitudes, education, and economic status affect the organization of youth marriage. The results also showed that there is a significant difference between the eight components of marriage organizing: the economic situation with a mean of 6/83, the first rank, and the best grade and component of the tradition with the average score of 1/89 and the lowest ranked students. It can be concluded that each of the factors of religion, customs, traditions, beliefs and beliefs, family and friends' attitudes, education and economic status affect the organization of youth marriage, but their degree of influence is different. So, the economics and attitudes of friends can have more impact than other components.
