摘要:AbstractThis study investigated cross-cultural differences in the privacy regulation and perception of crowding among two Iranian sub-cultures (Yazdi and Northern women). The research methodology was designed on interview and questionnaire. A random size of 100 Yazdi and Northern women was selected in Yazd and Sari cities. Moreover, to examine the survey Chi-Square Test, Independent Sample Test and Analysis of variance (ANOVA) were conducted. The results show that Yazdi women desired more privacy in public spaces than Northern women. Regardless of culture, women's desired and achieved privacy levels have associations with the level of perceived crowding in public spaces. These findings assist environmental designers to present strategies for achieving privacy in relation to Iranian sub-cultures.
