Other Interpretation

The world's Jewish population is a remarkable study in concentrated survival, constituting a nation-sized global diaspora where nearly half the world's Jews live in Israel, another half in a handful of other nations, yet collectively form just 0.2% of humanity—a testament to their enduring, outsized cultural and historical impact.
