Native Jordanians are mostly descended from people of villagers and Bedouin descent originating in the Arabian Peninsula.
In addition, there's Jordanian minorities like the Circassians, Chechens, Arameans and Armenians.
However, there are a number of other ethnicities present, including communities of Kurds, Assyrians and Mandeans which are refugees from the 2003 Iraqi war.
According to UNRWA, there are 1,951,603 Palestinian refugees in Jordan as of June 2008, 31.5% of Jordan's population.
Though that number doesn't include all Jordanians from Palestinian descent. There are also approximately one million Iraqis currently residing in the country.
Also, hundreds of thousands of guest workers from Egypt, Syria, Indonesia, and South Asia work as domestic and construction employees. Also, there are a few thousand residents of Lebanese origin who came to Jordan when civil strife and war broke out in their native country. They primarily reside in Amman.
The official language is Arabic, but English is used widely in commerce and government.
About 70% of Jordan's population is urban; less than 6% of the rural population is nomadic or semi-nomadic.
Most people live where the rainfall supports agriculture.
