Hejaz
Historically, the Hejaz has always seen itself as separate from the rest of Saudi Arabia. The Hejaz is the most populated region in Saudi Arabia; 35% of all Saudis live there. Hejazi Arabic is the most widely spoken dialect in the region. Saudi Hejazis are of ethnically diverse origins.
Eastern Arabic numerals
In Arabic-speaking Asia as well as Egypt and Sudan both kinds of numerals are used alongside each other with Western Arabic numerals gaining more and more currency, now even in very traditional countries such as Saudi Arabia. The United Arab Emirates uses both Eastern and Western Arabic numerals.
