According to the International Organization for Migration, there are 13 million, of which 5.8 million reside in Arab countries. Arab expatriates contribute to the circulation of financial and human capital in the region and thus significantly promote regional development. In 2009 Arab countries received a total of 35.1 billion USD in remittance in-flows and remittances sent to Jordan, Egypt and Lebanon from other Arab countries are 40 to 190 per cent higher than trade revenues between these and other Arab countries.
According to Saudi Aramco World, the largest concentration of Arabs outside the Arab World is in Brazil, which has 9 million Brazilians of Arab ancestry. Of these 9 million Arabs, seven million are of Lebanese ancestry, making Brazil's population of Lebanese greater than that of Lebanon itself. Most other Brazilians of Arab descent are mainly Syrian. Other large Arab communities includes Argentina, Venezuela,Colombia, Mexico (about 400,000 Mexicans of Lebanese descent) and Chile. Palestinians cluster in Chile and Central America, particularly El Salvador, and Honduras (between 150,000 and 200,000). The 500,000 strong Palestinian community in Chile is the fourth largest in the world after those in Israel, Lebanon, and Jordan. Arab Haitians (a large number of whom live in the capital) are more often than not, concentrated in financial areas where the majority of them establish businesses. In the United States, there are around 3.5 million people of Arab ancestry. Most Arabs of the Americas are of Lebanese, Syrian, or Palestinian ancestry. The Lebanese minority in America are mostly Christian, but with sizable Muslim and Jewish groups.
The Lebanese diaspora, while historically trade-related, has been linked more recently to the Lebanese Civil War, and the 2006 Lebanon War. In October 2006, shortly after the 2006 Second Lebanon War had concluded, the Edinburgh Middle East Report ran an article covering the brain drain from Lebanon's universities. Increasing numbers of Lebanese students are travelling abroad to further their education in safer environments.
As of June 21, 2007, the U.N. High Commissioner on Refugees estimated that over 2.2 million Iraqis had been displaced to neighboring countries, with up to 100,000 Iraqis fleeing to Syria and Jordan each month. As a result of growing international pressure, on June 1, 2007 the Bush administration said it was ready to admit 7,000 Iraqi refugees who had helped the coalition since the invasion. According to Washington-based Refugees International the U.S. has admitted fewer than 800 Iraqi refugees since the invasion, Sweden had accepted 18,000 and Australia had resettled almost 6,000.
As of 2012, at least 127,860 Iraqis live in Sweden. As of 2004, France is home to an estimated 5 to 6 million of people both Arabic and Berber speaking from North Africa. There is also a medium-sized Arab community in Australia (home to roughly 400,000 Arabs, mostly Lebanese), where Arabic is the fourth most widely spoken second-language. The number of Muslim and Christian Arab Australians are roughly equal with a slight Christian majority. See Australian population: ethnic origins.
