There has never been an accurate official census in Palestine since the roots of the recent aggression. Hadawi states that at the end of 1918 (WW1), there were 700,000 people living in Palestine. These were divided into 574,000 Muslims, 70,000 Christians and 56,000 Jews. Almost all the Palestinian Christians are Arabs and most of the Jews as well (up to around 1900 AD). These numbers check positively with the estimate that only 6% to 7% of the total Palestinian population was Jewish right after the first Zionist congress in Basel. It is also consistent with what David Newman's statement that: between 1800 and 1945, The Jewish Population of Palestine increased from approximately 25,000 to 600,000, eventually comprising some 33 per cent of the country's population.
