First you need to define the "Pacific North-West". Do you mean all of the west coast of North America, from California, through Canada, to Alaska?

Add up the populations of Washington, Oregon and Idaho and you have your answer.

Since that area is undefined (is Canada included? How far east is the cutoff?), no exact answer can be determined. Must be millions, but you can research that yourself with census statistics.
