•The main cause is the centralism. People from other departments come to modern cities to find a better life and job opportunities. In consequence migration increases every year.
•Since 1950 Lima has grown rapidly making it into a megacity.
From where do people migrate
•Most of the people come from the highlands and jungle because these kinds of regions face strong agrarian problems.
•The development of the principal cities causes this migration.
• Between 1940 and 1993 Lima´s population has grown from 645000 inhabitants to 6’565 inhabitants.
Urban growth has increased from 30 to 70% in the mayor cities in Peru. In consequence there is less farm land.
