List of odd-toed ungulates by population

This is a list of odd-toed ungulate species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.

This list is not comprehensive, as not all ungulates have had their numbers quantified.
