Arabs are at least a fifth of the population and Mohammad is the most popular Arab name. So it's not surprising when most Arabs name their kids Mohammad everywhere. Jews use a wider variety of names than Arabs.
Also, this only includes Israeli citizens. The PLO/Hamas Arab Muslim Nazis of Judea, Samaria, and Gaza are not included. So the Arab population of Israel is much higher than reported.
Does the information also include Israeli citizens that live abroad in the population?
