Qatar has a population of 2.6 million of which 313,000 are citizens, and the rest are expatriates. An Expatriate is someone temporarily or permanently living outside of their native country. I am not sure what the difference is from an Immigrant, other than perhaps intent. Is the relationship of an Expat purely commercial? With 90% of the population Expats, Qatar has the highest GDP per capita in the world at about $125,000 per person. Although a small country by population and size, it has the world's third-largest reserves of natural-gas. Qatar took part in the Arab Revolt that helped defeat the Ottoman Empire in World War I. The United Kingdom then gave recognition to the hereditary title of Sheikh Abdullah as leader of a 'Trucial State'. The area had previously been known as the Pirate Coast. The British controlled foreign policy, defence, and arbitration. Independence came in 1971. Qatar did not join the also newly formed federation of the United Arab Emirates.
