Populations in thousands from here. [Note that this is a very pro-Israel site, so feel free to mine it for pro-Israel / anti-Arab arguments]

1915 1931 1945 1967

Arabs 590 693 1061 390
Jews 83 175 553 2383

Some caveats about these numbers:
1) In some cases the number for Arabs is actually for all non-Jews.
2) The different years are for differing geographical locations. For example, the 1915 population figure is for "Palestine". The 1967 numbers are for Israel (1967 borders).

If there is any way to interpret these numbers as anything but the Jews pushing the Arabs out, then I'm interested to hear about it.

If this happened in Texas, the Jews would be hanging from telephone poles, and you'd be defending the Texans.
