I did not delve into the method of all these figures, but I find it mighty interesting to compare these album sales, per country / part of the world. And worldwide of course.
Who would have thought that the so much criticized albums No Prayer for the Dying and Fear of the Dark sold more, worldwide, than all the later albums. Yes they were released 8 to 10 years before Brave New World was released, but still! We're 21 years after Brave New World now.
It's also weird to see that Killers sold more than Seventh Son of a Seventh Son, worldwide.
