Argentina has almost 37 million inhabitants and is sparsely populated, only twelve people per square kilometer. The Argentine population is a mix of national and ethnic groups. 97% of the population is white and 2% of Indian origin. The white inhabitants are mainly the descendants of Italian and Spanish immigrants. In the urban areas there are also many immigrants from Syria, Lebanon and other countries in the Middle East. The remaining indigenous population lives mainly in the north, west and south. Nearly 95% of the population can read and write, and thus Argentina has the lowest illiteracy rate in all of South America.
