The Economist writes,
The 22 countries, including the unborn Palestine, that belong to the Arab League as “the Arab world” are home to a heterogeneous agglomeration of some 350m people. Maronites, Copts, Berbers, Kurds and Africans as well as Arabs and Muslims inhabit a miscellany of lands from the Atlantic to the Persian Gulf and from the Saharan desert to the foothills of Anatolia. One common characteristic, however, is the youthfulness of Arab society: the majority of Arabs are under 25 years old. But a shortage of jobs for the young means that political instability, in many Arabic countries, is likely to persist.
