'the White House', IPA: [adˈdaːr ɫbajdˤaːʔ]) is the largest city in Morocco and the country's economic and business centre. Located on the Atlantic coast of the Chaouia plain in the central-western part of Morocco, the city has a population of about 3.22 million in the urban area, and over 4.27 million in Greater Casablanca, making it the most populous city in the Maghreb region, and the ninth-largest in the Arab world.
Casablanca is Morocco's chief port, with the Port of Casablanca being one of the largest artificial ports in Africa, and the third-largest port in North Africa, after Tanger-Med (40 km or 25 mi east of Tangier) and Port Said. Casablanca also hosts the primary naval base for the Royal Moroccan Navy.
