Tunisian dinar
It is a criminal offence in Tunisia to import or export dinar. Every year, each citizen can convert into foreign currency up to 6,000 Tunisian dinars before departure from the country. Therefore, prices at duty-free shops are in convertible currencies such as euros, US dollars and British pounds. There are many converting ATMs in the country for tourists.
Tunis
Because of the concentration of political authority (headquarters of the central government, presidency, parliament, ministries and central government) and culture (festivals and mainstream media), Tunis is the only nationally ranking metropolis. Tunis is the heartland of the Tunisian economy and is the industrial and economic hub of the country, home to one third of Tunisian companies—including almost all the head offices of companies with more than fifty employees, with the exception of the Compagnie des Phosphates de Gafsa, headquartered in Gafsa—and produces a third of the national gross domestic product. Tunis attracts foreign investors (33% of companies, 26% of investments and 27% of employment), excluding several areas due to economic imbalances. According to the Mercer 2017 Cost of Living Rankings, Tunis has the lowest cost of living for expatriates in the world. The urban unemployment rate of university graduates is increasing and the illiteracy rate remains high among the elderly (27% of women and 12% of men). The number of people living below the poverty line, falling at the national level, remains higher in urban areas. In addition, unemployment is high in young people aged 18 to 24, with one in three unemployed as compared to one in six at the national level. In Greater Tunis, the proportion of young unemployed is at 35%.
