with most UNESCO world heritage sites. Demographics In 2010, there were 1.2 million people living in the greater Palermo area, 655,875 of which resided in the City boundaries, of whom 47.4% were male and 52.6% were female. People under age 15 totalled 15.6% compared to pensioners who composed 17.2% of the population. This compares with the Italian average of 14.1% people under 15 years and 20.2% pensioners. The average age of a Palermo resident is 40.4 compared to the Italian average of 42.8. In the ten years between 2001 and 2010, the population of Palermo declined by 4.5%, while the population of Italy, as a whole, grew by 6.0%. The reason for Palermo's decline is a population flight to the suburbs, and to Northern Italy. The current birth rate of Palermo is 10.2 births per 1,000 inhabitants compared to the Italian average of 9.3 births. , 97.79% of the population was of Italian descent. The largest immigrant group came from South Asia (mostly from Bangladesh and Sri Lanka): 0.80%, other European countries (mostly from Albania, Romania, Serbia, North Macedonia and Ukraine): 0.3%, and North Africa (mostly from Tunisia): 0.28%.

The original inhabitants were Sicani people who, according to Thucydides, arrived from the Iberian Peninsula (perhaps Catalonia). Antiquity In the 8th c. BC the Phoenicians built a small settlement on the natural harbour of Palermo, which became known as (, ). It became one of the three main Phoenician colonies of Sicily, along with Motya and Soluntum. The first settlement was later known as Paleapolis meaning "Old City". The site chosen by the Phoenicians was connected to the mountains with two roads that today have become Via Cappuccini and Corso Pisani. The Neapolis or "New City", the nucleus of the subsequent expansion of the colony, soon developed in the area between the Paleapolis and the port. The new district expanded rapidly, exceeding the size of the old quarter, and soon became the site of markets, artisan and commercial activities. The walls were extended to embrace the new urban perimeter and two new gates ere made, while the old gate at the port was moved to make room for the new
