'IMPORTANT NOTE

Many of the figures presented on this page must be incorrect, because they conflict with other reports. The purpose of showing these data is to examine the discrepancies. It is an abuse of the intent of this essay, and it is intellectually dishonest, to post one table or set of figures from this page in isolation, and to use those numbers to "prove" a political point about Jewish or Arab rights in Palestine.'
