The number of traditional fairs in Turkey has been gradually decreasing due to social, economic and technological developments. According to our ongoing project, samples of traditional fairs currently have been protecting their existence in 63 settlements located in 54 districts of 21 provinces in Turkey. Within the national-scale research project which investigates traditional fairs in Turkey, this paper attempts to explain factors determining motivation of visitors. With this purpose, 13 traditional fairs distributed over four geographical regions of Turkey have determined as sample area. It was aimed to conduct 200 surveys to visitors and 50 surveys to service providers (tradesmen) for each fair by considering gender and age groups limits. In total, 2582 and 611 surveys were conducted to visitors and tradesmen, respectively. It was aimed to evaluate relationships between the most utilised functions in traditional fairs (entertainment, shopping, picnic and etc.) and socio-economical characteristics of visitors (age, gender, education, income). For this purpose, non-parametric Chi-square Independency test were used to examine whether an independency or a relationship is exist between two variables. This test is based on hypothesis of significance between observed and expected frequencies. According to Pearson Chi-square values obtained from analyses, the factors affecting participation of visitors are found significant at 0.05 significance level according to gender, age groups, education and income variables. The relationship between some characteristics of visitors (age, gender, education, and income) and preferred sections is also found significant.
