Abstract: The analysis of processes that significantly affect the formation of future families, namely in the border region, as well as crisis phenomena in marital and family relations, demonstrates that religion is one of the important factors influencing these processes. Religious differences is one of the paramount and most complicated aspects that impacts mutual understanding and communication. Within the framework of family relationships, religious differences along with the cultural play a crucial role. The authors set a goal to determine the influence of religion upon the formation of marital and family relations within the environment of modern student youth. The conducted sociological survey involved the representatives of different nationalities and religious confessions (V=400 of the respondents – residents of Astrakhan and Astrakhan Region), which also allowed analyzing the impact of various factors, including religious, upon the formation of values of a modern young family. It is also worth noting that the acquired results testify to the fact that the majority of respondents hold an opinion on the insignificance of religious affiliation of a person in consummation of their own marriage. Since in most instances an interfaith marriage suggests conversion of one partner into religion of the other, the obtained data confirms that more it is a man who initiates such transition.
