Jordan contains some of the oldest Christian communities in the world, dating as early as the 1st century AD after the crucifixion of Jesus. Christians today make up about 4% of the population, down from 20% in 1930, though their absolute number has grown. This is due to high immigration rates of Muslims into Jordan, higher emigration rates of Christians to the West and higher birth rates for Muslims. Jordanian Christians number around 250,000, all of whom are Arabic-speaking, according to a 2014 estimate by the Orthodox Church, though the study excluded minority Christian groups and the thousands of Western, Iraqi and Syrian Christians residing in Jordan. Christians are exceptionally well integrated in the Jordanian society and enjoy a high level of freedom. Christians traditionally occupy two cabinet posts, and are reserved nine seats out of the 130 in the parliament. The highest political position reached by a Christian is the Deputy Prime Minister, currently held by Rajai Muasher. Christians are also influential in the media. Smaller religious minorities include Druze, Baháʼís and Mandaeans. Most Jordanian Druze live in the eastern oasis town of Azraq, some villages on the Syrian border, and the city of Zarqa, while most Jordanian Baháʼís live in the village of Adassiyeh bordering the Jordan Valley. It is estimated that 1,400 Mandaeans live in Amman, they came from Iraq after the 2003 invasion fleeing persecution.
