This chapter summarizes and analyzes the latest World Values Survey data on attitudes toward tax evasion in Turkey. In addition to examining the overall viewpoints of the 1601-person sample, we examine ethical attitudes from the perspective of the following demographic variables: gender, age, marital status, education level, employment status, occupation, social class, income level, happiness, position on the political spectrum, sector of employment, and confidence in government. Comparisons with other studies will be made to determine the similarities and differences between Turkish attitudes and the attitudes of people in other countries.
