# List of Apodiformes by population

This is a list of Apodiformes 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 Apodiformes have had their numbers quantified.
