As I noted in my review of Shall the Religious Inherit the Earth (also see John Derbyshire’s review) “In 1960 15 percent of elementary age students in Israel were Arab or Haredi. In 2010 ~50%….” Additionally, while the Arab Israel TFR has been dropping, that of the ultra-Orthodox has not. In 2001 30% of births in Israel were to Arab Israelis. In 2008 25% were. The difference was a function of dropping Arab fertility combined with no decrease among the ultra-Orthodox. Projecting current trends 40 years the Haredi will be a majority of Israelis. I don’t think this projection is reasonable though, at some point the lack of proportionate Haredi participation in the labor force will result in a fiscal crisis and the Israeli nation will have to restructure itself.
