The population of the city of Tunis exceeds 2,000,000 inhabitants. After independence, the Tunisian government implemented a plan to cope with the population growth of the city and country, a system of family planning, to attempt to lower the rate of population growth. However, between 1994 and 2004, the population of the governorate of Tunis grew more than 1.03% per annum. It represents, in the 2004 census, 9.9% of the total population of Tunisia. As in the rest of Tunisia, literacy in the region of Tunis evolved rapidly during the second half of the 20th century and has reached a level slightly higher than the national average. The education level is only exceeded by the neighboring governorate of Ariana which has many institutions of education.
