* Correction. On taking another look, I saw that Jews are shown, and am amazed at how small the chart shows them to be. 0.23% Can that be right? Are there really so few Jews? This shows them to be outnumbered by Sikhs, outnumbered by atheists. Only Baháʼí are shown to be less numerous than Jews.
The number of Jews in the world is 16 million. World population is 8 billion. Actually, yeah, about right. 16MM /8 Bn = .2%.
