Israel has the highest density of tech start-ups in the world. Comparing the density of startups in Israel vs. the entire US or the entire European region is misleading, because the US and Europe are so much larger and more heterogenous. It would be more accurate to compare the density of startups in Israel vs. Silicon Valley (comparable geographic area and population).
