Some other surveys also have slightly different numbers but Judaism really never goes over 15 million…Yet it seems to be the target of most controversy, but when you consider that there are 11 other religions or belief systems with a greater population then Judaism why don’t those belief systems get more coverage?
First of all, this is one set of statistics that differs quite a bit from others I’ve seen. In the second place, the groups mentioned are not all of the same kind. For instance, “secular/nontheistic/atheist/etc.” is a broad category defined purely in negative terms. It’s not a “belief system” at all–people falling under that category no doubt have a wide variety of belief systems. Similarly, “traditional Chinese religion” is a set of cultural practices rather than an organized religion. And so on.
The traditional “big five” (someone else mentioned a “big three,” but those are just monotheistic religions) are Hinduism, Buddhism, Judaism, Christianity, and Islam. These are the ones I focus on in my “Religions of the World” course (though less on Christianity, because we are a Christian college and the students take other courses dealing with Christianity). Of course, even among these five there are huge differences–is Hinduism really a “religion” in the same way Christianity is, for instance? But these are the five traditions that folks tend to focus on.
This is not because of numbers. I am not sure where you get the assumption that one focuses on religious groups primarily because of the numbers of their adherents. Obviously this is one factor, but another huge one is cultural influence and influence on other religions. That’s why Judaism is important. Judaism is in some sense the root tradition for the other two “Abrahamic” religions–Christianity and Islam. It has also had a huge cultural impact, not only through the Hebrew Bible and its appropriation by Christianity (and its echoes in Islam) but through the contributions Jews have made to Western and Middle Eastern culture.
Sikhism, by comparison, may have more adherents, but it is a derivative of Hinduism heavily influenced by Islam. When you understand Hindu bhakti devotionalism, and you understand Sufi mysticism, you have many of the basic ideas of Sikhism already. So in my course I spend one day on Sikhism, sometimes two, while spending two to three weeks on Judaism. And I think this is thoroughly defensible. The academic study of religion is not “one person, one vote.” It focuses on movements that are deemed to be particularly important.
That doesn’t mean that Sikhism isn’t deserving of a lot more attention than it usually gets. It is. But Judaism is fully deserving of all the attention it gets.
