The numbers of the indigenous Palestinian people
Joan Peters in her research calculated that in 1882, just the non-nomadic, settled Muslims in Palestine numbered 141,000. Among them, those that resided in Palestine before the 1831 Egyptian invasion numbered 75 percent, or 105,700.
If we calculate these 105,700 indigenous Muslims population based on natural rates of population growth according to the same rate as the populations of neighboring Syria, Egypt and Lebanon for which rates we have reliable data. That rate of growth was 1.1% per annually. Using a compounded interest formula the number of total Muslims descendants of those native people in 2015 yields a total number of 453,000.
According to the 2015 World Almanac, the “Palestinian” population, including Israeli Arabs, and Arab residents of Gaza, Golan, Judea and Samaria totals 10,523,715 people. 453,000 descendants of indigenous Muslim residents constitute only 4.3% of these “Palestinian” population. Therefore the other 95.7% of present-day “Palestinians” are clearly those Arabs and their descendants who migrated to Israel between 1831 and 2015.
