Abidjan instance of million city
By 1950, Abidjan had just exceeded a population of 50,000 (at the end of 1948). Reaching a population of a million by the end of 1975, the city grew at a rate of 10 to 12% per year, doubling every six or seven years. However, this growth underwent a sharp decline due to the crises of the 1980s and 1990s. In the last 20 years of the 20th century, the growth rate dropped to 3–6%. Birth rate growth was supplemented by migration, with the influx being substantial and the outflow only partly offseting the arrivals. The migration, prior to the census of 1988, contributed a growth of about 80,000 with 50,000 people from within Côte d'Ivoire, and about 30,000 from abroad per year.
From within Côte d'Ivoire, the migration pattern was dominated by Akan (South-east, 48%), then Mandé (North-west, 24%) and Krou (South-west, 20%). From abroad, the migration was Burkinabes (30%), Malians (22%), Ghanaians (19%), Nigerien (11%), and Guineans (9%). Of the non-African migration, Lebanese migration was highest, followed by European migration, with the French being largest of this latter group. All in all, people of non-African origin represent 3% of the total population of Abidjan, which remains the highest in the region.
