A short WINEP article:
While Syrians constitute the largest segment of foreign nationals in Jordan, however, the census shows that some 3 million of its 9.5 million residents are not Jordanian. These include nearly 636,000 Egyptians, 131,000 Iraqis, 31,000 Yemenis, 23,000 Libyans, and 634,000 non-naturalized Palestinians.
