Mandatory Palestine (roughly Israel + Palestinian Territories today) had a population of ~750k in 1920 [0]. The population of Israel today is ~9m [1] and of the Palestinian territories another ~5m [2]. It would have probably still been a massive increase even without the migration of Jews into what is now Israel, as there are ~13m [3] Palestinians world-wide today and most of them live in the middle east (PT, Israel & refugees in neighboring countries). You can see similar albeit less extreme growth in neighboring countries (e.g. Egypt went from ~13m to ~100m in the same period). Like Oblio I would guess this is common for countries who were unindustrialized in 1920 as they have seen massive reduction in child mortality & massive increase in food supplies due to advances in modern medicine & agriculture in the last 100 years.
