No, what i said is that the poorer the nation (and in turn the higher propensity for religious fever), the higher the name rate is the big cheese himself.
Be that Jesus, Or Mohammad.
Whereas in the less desperete places they tend to go for religiously linked names but not to choose the leader of the religion.
Strange huh? And not always true but run the numbers yourself and you will probably agree that there is some correllation there.
I see what you mean, I'd agree that piety is related to poverty. The more prosperous an individual the less likely they are to be inately devout.
However, the name Jesus is as common among wealthier Hispanic communities as the poorer so I expect the convention for naming children is more based in the culture than relative wealth.
