Here is what the online dictionary says about race:

"A local geographic or global human population distinguished as a more or less distinct group by genetically transmitted physical characteristics.
"A group of people united or classified together on the basis of common history, nationality, or geographic distribution: the German race.
"A genealogical line; a lineage.
Humans considered as a group.
"Biology.
"An interbreeding, usually geographically isolated population of organisms differing from other populations of the same species in the frequency of hereditary traits. A race that has been given formal taxonomic recognition is known as a subspecies.
"A breed or strain, as of domestic animals.
"A distinguishing or characteristic quality, such as the flavor of a wine."

According to that, one might easily refer to the 'English race' or to the 'Canadian race' or the 'Amish race', inexact as it may be.
