assuming you mean real not virtual processors. World population is 6.5B. Optimistically 25% can afford any electronics with 32bit processors (i.e. percentage not preoccupied solely with survival and bare necessities). Roughly 1.6B. Some have many (pc, laptop, pda, camera, mobiles); if on the average each person has 2 - including those collecting dust in the closet - that's 3.2B. It jibes with the estimated total number of mobile subscribers (about 2.6B) worldwide. wouldn't manufacturers keep track of unit production?
