Israeli media grossly misinterpreted a recent demographic study by Ariel University. According to the report, population growth in the settlements is thrice the Israeli average during the last twelve years. In reality, most of the increase occurred as Israelis, many of them new and poor immigrants, moved to the cheaper West Bank housing. The West Bank’s birth rate is 35 per 1,000 compared to the Israeli average of 20.
But – haredi Jews compose 30 percent of the West Bank population, four times the national average. They have a birth rate approximately four times higher than the national average, so we can guess reliably a birthrate of 80 per 1,000. Thus, out of 1,000 Israeli settlers there are 300 haredim with 24 children; the other 700 settlers have 35-24=11 children, or about 15 per 1,000 – somewhat below the national average of 20 per 1,000. This is because there are plenty of small atheist families in the West Bank, just as in Small Israel.
