Those population statistics you are citing Wolfgang, grossly distort the population realities of the region. Here are some facts which more accurately represent the intentional Zionist political settlement of the Jewish population in the region:

Population and Modern Palestine of the 1920-1947 British Mandate Period:

In-Migration and Demographic Transformation: Palestine in 1882 had a small, native, and migrant religious Jewish community of roughly 24,000 among a Palestinian population of nearly 500,000. There were several waves of politically inspired immigration into the country. The first occurred between 1882 and 1903 and totaled about 25,000. The second, between 1904 and 1914, brought in around 35,000 immigrants, which resulted in a total Jewish population of 85,000. The third wave between 1919 and 1923 brought another 85,000 immigrants, mostly Polish and middle class. The December 1931 British census of the country showed that of the 1.04 million people, 84 percent were Arab and 16 percent were Jewish. While the increase in the Jewish population was due largely to in-migration, the Palestinian population increased naturally at 2.7 percent per year. Because of the rise of Nazism, 174,000 Jews migrated to Palestine between 1932 and 1936. Suddenly the Jewish population in Palestine rose to an estimated 28 percent of the total inhabitants. This radical change, occurring in a brief span of only five years, must certainly be recognized as an important cause of the Palestinian Arab rebellion of 1936 against British Mandate authorities. Both legal and illegal Jewish immigration (according to Mandate authorities) into Palestine increased during World War II and its aftermath. By the end of 1947, Palestine Mandate government estimates indicate that of a total population of 1.9 million, Jews made up only 31 percent. Thus, only a year before the state of Israel was unilaterally declared, the Jewish population constituted less than one-third the total inhabitants. Nevertheless, the Jewish minority in Palestine became a powerful community.
