The Kurd population, stretching across at least 4 countries, with a diaspora in many more, historically has been hard to quantify. In 1987, estimates suggested that probably numbering close to 16 million kurds, inhabits the wide arc from eastern Turkey and the northwestern part of Syria through Azerbaijan and Iraq to the northwest of the Zagros Mountains in Iran, respresented the population of what has been referred to as "Kurdistan." About half of all Kurds worldwide lived in Turkey. Most of the rest lived in adjacent regions of Iran, Iraq, and Syria. They represent by far the largest non-Arab ethnic minority of Iraq, accounting in 1987 for about 19 percent of the population, or around 3.1 million, and also Turkey's largest non-Turkish ethnic group. By 2008 Turkey still had the dominant Kurdish population in the region, with an estimated 14 million. Iraq was estimated to have a population of some 4-6 million Kurds, with another 4-5 million in Iran. Kurdish populations that represented less than 10 percent of the total population continued by that time in countries such as Syria and Azerbaijan as well.
To my knowledge, I haven't met a Kurd.
