19 ~5.42mln (+ ~300k outside top 40) -> so 5.7mln+
US+UK - 4.4mln+
Canada - 100k+(?)
Japan ~70k(including deluxe edition -> counted separately)
19's sales could stand @ 5.85-5.9mln IMO. It was not a big hit in other countries even after 21's release, but I might be wrong...
What about Brazil? I believe it made the Top 10 there...
In Canada 19 was certified double platinum (200k) in May 2012
In Spain it's been certified platinum (80k) for a long time
In Ireland it was the 3rd biggest selling artist album of 2011 behind 21 and buble. Considering it's sales ratio compared to 21 is probably similar to that in the UK (2.1m:4.4m), and 21 has sold ~240k in Ireland, I would imagine 19's sales could be close to 100k there.
So if you adjust Canada and add Ireland/Spain to the above list, that makes a total of 5.9 million.
Then you have Belgium: ~30k, Italy: ~35k, Scandinavia: ~45k+, NZ: ~15k
That's another ~125k+ to add, which makes a total of 6.1 million.
And that's before adding the rest of the world.
What do you think Arab, does that seem reasonable?
