That Ramallah was not mentioned in historical sources does not mean they it did not exist or negates its importance, for there are many remnants of human populations that inhabited Ramallah throughout its extensive history. Yet these populations had built a civilization of their own in a certain site in Ramallah. And each site has its own name. There is no doubt that these human populations have mutual relationships, and some of these populations flourished while others perished, then others inhabited these sites and so on.
Circumstances have caused people to continue living in Khirbet Ramallah (the old town) and for it to be bought by the sheikh of the Haddadeen tribe which led to a thriving and expanding Ramallah that contained, as it flourished, the rest of the human populations. This later caused everyone to be part of one civilized entity under one name, Ramallah.
These human populations, of which we have not obtaind much information, except for whatever its residents had left us was manifested in Kafr Ghamla (Al-Tira), Khirbet Radana, Khirbet Ramallah (the old town), Khillat Al-'Adas, Al-Kafriyyah, Tarfidya, Al-Krei’nah, and other human habitation locations that have become part of the twin city city, Al-Bireh.
The population of the city of Ramallah is 32,000 people. The city is surrounded by 80 towns and villages. The total number of residents of the city and its environs is 278,000 people. The following table reveals the population growth in the Ramallah and Al-Bireh cities from 1912 to 1985.
The table indicates that the cities of Ramallah and Al-Bireh had seen an increasing population growth despite being influenced by political conditions that affected it like the rest of the Palestinian cities. In 1922, its population consisted of 4,582 people, which was a drop from the population in 1912. This was due to the immigration movement that the city had seen in the wake of the First World War. The population count then continued to increase and reached 8,000 people in 1945. In 1952, the population count made a significant leap to 26,225 people due to the influx of large numbers of Palestinian refugees in the aftermath of the 1948 war.
The population growth continued until it reached 32,781 people immediately before the 1967 war, while the population dropped to 25,171 people immediately after the war due to exodus witnessed by the city in the aftermath of the war.
