Anthro / Geo. Hydro view would be “97% of water is saline” and Ethno “4 religions account for over 77% of the world's population”

Please correct me if I’m wrong.

Ethnic is not relative to religion per se, but language and traditions.

For what I find on search engines, Ethno is relative to race, people, culture. that includes language, traditions and religions.
