Your numbers look like they come from the utterly discredited book "From Time Immemorial." There was no where near, not even close, to 40% Jewish population in the Late Ottaman period.  Utterly laughable and Trump like "alternative facts." Give me a footnote.

A Palestinian identity had arose in the late Ottoman Empire.  The term Palestine had been used since Aristotlelian times.  The Palestinians have an unbroken occupation in Palestine.  Genetic studies show that todays Palestinian are related to the biblical Jews.  Which makes since, since they are the indigenous people of that area.  The Ashkenazi Jews came from Europe in a colonial enterprise to usurp Palestinian lands.  Too bad they cannot accept a glaringly good deal and take 78% of the land.  Instead they keep stealing more Palestinian lands.
