The exact number of Zazas is unknown, due to the absence of recent and extensive census data. The last census on language in Turkey was held in 1965, where 150,644 people ticked Zaza as their first language and 112,701 as their second language. More recent data from 2005 suggests that the Zaza-speaking population varies from approximately 2 to 4 million. Many Zazas only speak Kurmanji Kurdish as it was believed that the Zaza language was an offshoot of Kurmanji. According to a 2019 KONDA survey, about 1.5 million people identified themselves as Zaza. Following the 1980 Turkish coup d'état, many intellectual minorities, including Zazas, emigrated from Turkey towards Europe, Australia and the United States. The largest part of the Zaza diaspora is in Europe, predominantly in Germany.
Ethnic consciousness
While Zazas largely consider themselves Kurds, some researches do consider Zazas as an ethnic group and treat them as such in their academic work.
Zaza is a Northwest Iranian language, spoken in the east of modern Turkey, with approximately 2 to 3 million speakers. There is a division between Northern and Southern Zaza, most notably in phonological inventory, but Zaza as a whole forms a dialect continuum, with no recognized standard. The first written statements in the Zaza language were compiled by the linguist Peter Lerch in 1850. Two other important documents are the religious writings of Ehmedê Xasi of 1898, and of Usman Efendiyo Babıc ; both of these works were written in the Arabic alphabet. The state-owned TRT Kurdî airs shows in Zaza. During the 1980s, Zaza language became popular among diaspora Zazas after meager efforts which was followed by publications in Zaza in Turkey.
Religion
Around half of the Zaza population adhere to Alevism and these predominantly live around Tunceli. The other half adhere to Sunni Islam, both Hanafi and Shafi‘i, whereas the Shafi‘i followers are mostly Naqshbandi. Historically, a Christian Zaza population existed in Gerger.
Zaza nationalism
Zaza nationalism is an ideology that supports the preservation of Zaza people between Turks and Kurds in Turkey. Turkish nationalistHasan Reşit Tankut proposed in 1961 to create a corridor between Zaza-speakers and Kurmanji-speakers to hasten Turkification. In some cases in the diaspora, Zazas turned to this ideology because of the more visible differences between them and Kurmanji-speakers. Zaza nationalism was further boosted when Turkey abandoned its assimilatory policies which made some Zazas begin considering themselves as a separate ethnic group. In the diaspora, some Zazas turned to Zaza nationalism in the freer European political climate. On this, Ebubekir Pamukchu, the founder of the Zaza national movement stated: "From that moment I became Zaza." Zaza nationalists fear Turkish and Kurdish influence and aim at protecting Zaza culture and language rather than seeking any kind of autonomy within Turkey. According to researcher Ahmet Kasımoğlu, Zaza nationalism is a Turkish and Armenian attempt to divide Kurds.
