Historically, the Yazidis lived primarily in communities located in present-day Iraq, Turkey, and Syria and also had significant numbers in Armenia and Georgia. However, events since the end of the 20th century have resulted in considerable demographic shift in these areas as well as mass emigration. As a result, population estimates are unclear in many regions, and estimates of the size of the total population vary.
The majority of the Yazidi population lives in Iraq, where they make up an important minority community. Estimates of the size of these communities vary significantly, between 70,000 and 500,000. They are particularly concentrated in northern Iraq in Nineveh Governorate. The two biggest communities are in Shekhan, northeast of Mosul and in Sinjar, at the Syrian border 80 kilometres (50 mi) west of Mosul. In Shekhan is the shrine of Sheikh Adi ibn Musafir at Lalish. In the early 1900s most of the settled population of the Western Desert were Yazidi. During the 20th century, the Shekhan community struggled for dominance with the more conservative Sinjar community. The demographic profile has probably changed considerably since the beginning of the Iraq War in 2003 and the fall of Saddam Hussein's government.

According to the Human Rights Watch, Yazidis were under the Arabisation process of Saddam Hussein between 1970 and 2003. In 2009, some Yazidis who had previously lived under the Arabisation process of Saddam Hussein complained about the political tactics of the Kurdistan Regional Government that were intended to make Yazidis identify themselves as Kurds. A report from Human Rights Watch (HRW), in 2009, declares that to incorporate disputed territories in northern Iraq—particularly the Nineveh province—into the Kurdish region, the KDP authorities had used KRG's political and economical resources to make Yazidis identify themselves as Kurds. The HRW report also criticises heavy-handed tactics."
Yazidis in Syria live primarily in two communities, one in the Al-Jazira area and the other in the Kurd-Dagh. Population numbers for the Syrian Yazidi community are unclear. In 1963, the community was estimated at about 10,000, according to the national census, but numbers for 1987 were unavailable. There may be between about 12,000 and 15,000 Yazidis in Syria today, though more than half of the community may have emigrated from Syria since the 1980s. Estimates are further complicated by the arrival of as many as 50,000 Yazidi refugees from Iraq during the Iraq War.
The Yazidi population in Georgia has been dwindling since the 1990s, mostly due to economic migration to Russia and the West. According to a census carried out in 1989, there were over 30,000 Yazidis in Georgia; according to the 2002 census, however, only around 18,000 Yazidis remained in Georgia. However, by other estimates, the community fell from around 30,000 people to fewer than 5,000 during the 1990s. Today they number as little 6,000 by some estimates, including recent refugees from Sinjar in Iraq, who fled to Georgia following persecution by ISIL. On 16 June 2015, Yazidis celebrated the opening of a temple and a cultural centre named after Sultan Ezid in
Varketili, a suburb of Tbilisi. This is the third such temple in the world after those in Iraqi Kurdistan and Armenia.
According to the 2011 census, there are 35,272 Yazidis in Armenia, making them Armenia's largest ethnic minority group. Ten years earlier, in the 2001 census, 40,620 Yazidis were registered in Armenia. They have a significant presence in the Armavir province of Armenia. Media have estimated the number of Yazidis in Armenia to be between 30,000 and 50,000. Most of them are the descendants of refugees who fled to Armenia in order to escape the persecution that they had previously suffered during Ottoman rule, including a wave of persecution which occurred during the Armenian Genocide, when many Armenians found refuge in Yazidi villages.
The Ziarat temple in Aknalich, Armenia
There is a Yazidi temple called Ziarat in the village of Aknalich in the region of Armavir. Construction on a new Yazidi temple in Aknalich, called "Quba Mere Diwan," is underway. The temple is slated to become the largest Yazidi temple in the world and is privately funded by Mirza Sloian, a Yazidi businessman based in Moscow who is originally from the Armavir region.
The Yazidi community of Turkey declined precipitously during the 20th century. Most of them have immigrated to Europe, particularly Germany; those who remain reside primarily in their former heartland of Tur Abdin.
This mass emigration has resulted in the establishment of large Yazidi diaspora communities abroad. The most significant of these is in Germany, which now has a Yazidi community of more than 200,000 living primarily in Hannover, Bielefeld, Celle, Bremen, Bad Oeynhausen, Pforzheim and Oldenburg. Most are from Turkey and, more recently, Iraq and live in the western states of North Rhine-Westphalia and Lower Saxony. Since 2008, Sweden has seen sizeable growth in its Yazidi emigrant community, which had grown to around 4,000 by 2010, and a smaller community exists in the Netherlands. Other Yazidi diaspora groups live in Belgium, Denmark, France, Switzerland, the United Kingdom, the United States, Canada and Australia; these have a total population of probably less than 5,000.
