been assimilated into the population over the millennia, with influences of population from Phoenicians/Carthaginians, Romans, Vandals, Arabs, Spaniards, Ottoman Turks and Janissaries, and French. There was a continuing inflow of nomadic Arab tribes from the Arabian Peninsula. After the Reconquista and expulsion of non-Christians and Moriscos from Spain, many Spanish Muslims and Jews arrived in Tunisia. According to Matthew Carr, "As many as eighty thousand Moriscos settled in Tunisia, most of them in and around the capital, Tunis, which still contains a quarter known as Zuqaq al-Andalus, or Andalusia Alley." Languages Arabic is the official language of Tunisia. Tunisian Arabic, known as Tounsi, is the national, vernacular variety of Arabic used by the public. There is also a small minority of speakers of Berber languages known collectively as Jebbali or Shelha in the country. French also plays a major role in Tunisian society, despite having no official status. It is widely used in education (e.g., as the language of instruction in the sciences in secondary school), the press, and business. In 2010, there were 6,639,000 French-speakers in Tunisia, or about 64% of the population. Italian is understood and spoken by a small part of the Tunisian population. Shop signs, menus and road signs in Tunisia are generally written in both Arabic and French. Religion Tunisia's constitution declares Islam as the official state religion—and the absolute majority of its population, or around 98%, report to be Muslims, while some 2% follow predominantly Christianity or Judaism. According to a 2018 survey conducted by the Arab Barometer, the vast majority of Tunisians (99.4%) continue to identify as Muslim. The survey also found that more than one third of Tunisians identify as non-religious. The percentage of Tunisians identifying themselves as non-religious has recently increased from around 12% in 2013 to around 33% in 2018, making Tunisia the least religious country in the Arab world. Nearly half of young Tunisians described themselves as non-religious, according to that same survey. The most recent 2021 Arab Barometer survey reported that 44% of Tunisians consider themselves religious, 37% somewhat religious, and 19% non-religious. Tunisians enjoy a significant degree of religious freedom, a right enshrined and protected in its constitution, which guarantees the freedom of thoughts, beliefs and to practice one's religion. The country has a secular culture where religion is separated from not only political, but also public life. Individual Tunisians are tolerant of religious freedom and generally
