(Catholic Encyclopedia)
Present condition of the City (1905)
""5. Jerusalem (El Quds) is the capital of a sanjak and the seat of a mutasarrif directly dependent on the Sublime Porte. In the administration of the sanjak the mutasarrif is assisted by a council called majlis ida ra; the city has a municipal government (majlis baladiye) presided over by a mayor. The total population is estimated at 66,000.
The Turkish census of 1905, which counts only Ottoman subjects, gives these figures:
Jews, 45,000; Moslems, 8,000; Orthodox Christians, 6000; Latins, 2500; Armenians, 950; Protestants, 800; Melkites, 250; Copts, 150; Abyssinians, 100; Jacobites, 100; Catholic Syrians, 50. During the Nineteenth century large suburbs to the north and east have grown up, chiefly for the use of the Jewish colony. These suburbs contain nearly Half the present population..""

... Haifa, Ashdod, Ashqelon which are not part of israel right now, just under israeli occupation. That's the formal legal status.
'Palestinians' (the term is so Fuzzy and new for 'arabs'), Don't have a right to come to Israel.
All of the Refugees were the result of the Arab-Started War in 1948.
Israel was created in 1948 from Res 181. No one was Forced to leave.
It was a partition-for-Rule/Change of sovereignty for some arabs, but NO ONE had to leave.
Many did leave at the Urging of Arab leaders to get out of the way while they wiped out the Jews.. to return and collect the spoils. That's War.
Of the original 600,000 refugees only perhaps a few thousand are even living.
However, this Ridiculous situation has now balooned/ PREPOSTEROUSLY to 4 Million, 2nd, 3rd, and even 4th generation 'refugees'.
Many didn't leave/Stayed in Israel, now comprising 20% of it's populace.
All the OTHER refugee groups of the period have been settled.
2 MILLION 1945 Sudeten Germans, moved and absorbed by their Brethren.
10's of MILLIONS fom the 1947 Pak/India Partition.. all moved and settled.
The above not only setttled but Codified in Law there is NO 'right of return'.
Only a few hundred thousand 'palestinians' are not settled!
Kept in Refugee Camps by THEIR Arab Brethren; DENIED Citizenship, Land Ownership, and Jobs, to be used as Pawns against The Jews.
