RAMALLAH, July 8 (Xinhua) -- The number of Palestinians living in the West Bank and Gaza Strip is estimated at 4.05 million, Palestinian Central Bureau of Statistics (PCBS) said Thursday.

About 2.51 million of the population lives in the West Bank and 1.54 million in the Gaza Strip, PCBS said in a report issued ahead of the World Population Day which falls on July 11, adding there are 2.06 million males and 1.99 million females.

The city of Hebron is the highest populated area in the West Bank, as the report said some 600,000 people live there.

In the Gaza Strip, where the Islamic Hamas movement holds sway since 2007, Gaza city witnesses the highest number of residents, 535,000, compared to other areas in the coastal enclave.

The report also revealed that the Palestinian territories have a young population, as people aged under 14 constitute 41.3 percent of the total population.

The Palestinians believe that having more children and extended families is part of the national struggle to make a demographic domination over Israel.
