I'm not sure where the 100 million estimate comes from, either, but on the other hand, I have no idea what your reports have stated. I'm not clear on how religious motivation should exaggerate their data. Does it help to intentionally overreport and claim that religious people are underrepresented? Is it better to intentionally underreport and go for the angle of persecuted minority group, so that the greater international community, and perhaps even the general populace would have sympathy? Maybe both, depending on the situation. Are there studies on the difference in accounting of the number of self-professing religious believers in a population as reported by religious and nonreligious sources?
