UN General Assy Resolution 181
The Arab leadership opposed the plan, arguing that it violated the rights of the majority of the people in Palestine, which at the time was 67% non-Jewish (1,237,000) and 33% Jewish (608,000).
They criticised the amount and quality of land given to Israel. The Jews had been offered 55% percent of the land when they only owned 7%. Although it should be noted that much of the land area was not actually owned by anyone (Jewish or Arab) -- it was desert under the control of the British Mandate.
The population for the proposed Jewish State would be 498,000 Jews and 325,000 non-Jews. The population for the proposed Arab State would be 807,000 non-Jews and 10,000 Jews. The population for the proposed International Zone would be 105,000 non-Jews and 100,000 Jews.
