Trans-Jordan exported unskilled casual labor to Palestine; but before 1948 its civil service attracted a good many educated Palestinian Arabs who did not find work in Palestine itself. Demographically speaking, however, neither movement of population was significant in comparison to the decisive factor of natural increase. Daniel Pipes responded to Porath by granting that From Time Immemorial quoted carelessly, used statistics sloppily, and ignored inconvenient facts. Nonetheless, he explained that:Miss Peters's central thesis is that a substantial immigration of Arabs to Palestine took place during the first half of the twentieth century. She supports this argument with an array of demographic statistics and contemporary accounts, the bulk of which have not been questioned by any reviewer, including Porath.Porath replied with an array of demographic data to support his position. He also wrote that Peters's demographic statistics were inexplicable: ...nowhere in her main text or in the methodological appendices (V and VI) did Mrs. Peters bother to explain to her readers how she managed to break down the Ottoman or Cuinet's figures into smaller units than subdistricts. As far as I know no figures for the units smaller than subdistricts (Nahia; the parallel of the French commune), covering the area of Ottoman Palestine, were ever published. Therefore I can't avoid the conclusion that Mrs. Peters's figures were, at best, based on guesswork and an extremely tendentious guesswork at that. Modern era , Israeli and Palestinian statistics for the overall numbers of Jews and Arabs in the area west of the Jordan, inclusive of Israel and the Palestinian territories, are similar and suggest a rough parity in the two populations. Palestinian statistics estimate 6.1 million Palestinians for that area, while Israel's Central Bureau of Statistics estimates 6.2 million Jews living in sovereign Israel. Gaza is estimated by the Israeli Defense Forces (IDF) to have 1.7 million, and the West Bank 2.8 million Palestinians, while Israel proper has 1.7 million Arab citizens. According to Israel's Central Bureau of Statistics, as of May 2006, of Israel's 7 million people, 77% were Jews, 18.5% Arabs, and 4.3% "others". Among Jews, 68% were Sabras (Israeli-born), mostly second- or third-generation Israelis, and the rest are olim – 22% from Europe and the Americas, and 10% from Asia and Africa, including the Arab countries. According to these Israeli and Palestinian estimates, the population in Israel and the Palestinian territories stands at from 6.1 to 6.2 million Palestinians and
