Family is the primary institution in which the initial experiences of social relations take shape. Human beings are born into families and form their own families in return. The present study concerns the major preferences and criteria that Iranians hold for selecting the right spouse. The main question of the study is about the transformations that spouse choosing, and its underlying criteria, have undergone. It assesses the attitudinal aspects regarding the "ideal spouse" and is concerned about the choice of either husband or wife. The chief method of the study is secondary analysis of quantitative data gathered at the national level. The sources of the research are comprised of all surveys that measure Iranians 15 years old and above. The findings of the research indicate that the changes of Iranians' understanding of the "ideal spouse" have been next to nothing. People's behavioural patterns in choosing a spouse do not entirely match their attitudinal preferences; in other words, despite the change in behaviour, Iranians' preferences for the ideal spouse has hardly changed in attitude.
