presently i don't agree with those numbers you talked about. In my researches (in the last 9 years) i have a figure of 12 MILLION worldwide at the time of release of "Rattle and Hum", what means roughly 7 million outside USA.
Other figure appeared in the press when "Achtung Baby" was released in 1991, it was 14 MILLION worldwide.
The sales figures on the UKMix thread are all of almost 8 years after the initial release so they give accurate sales after all that time.
In my opinion "The Joshua Tree" sold more than 20 MILLION, how much more i still don't have an definite estimation, i will analyse that in some weeks time in the UKMix forum.
Take a look at the thread there if you are interested in this kind of stuff (sales).
Estimating the Joshua Tree's sales levels without the precise information for all of Europe and other regions of the world can be difficult. But, one should pay attention to the earliest sales figures which were mentioned in 1987 first, because often what happens is that further reports do not accurately update the sales information. They simply use the old figures from the first year of release. This appears to be what happened with the figures you listed above.
Even using your figure for the time of release for Rattle And Hum of 12 million, the Joshua Tree sold a further 5 million copies in the United States alone by September 1995 which would put total global sales well beyond 17 million copies by September 1995 once sales outside the United States after October 1988 are considered.
I believe the true figure for the Joshua Tree is very close to 30 million, probably around 28 million to be exact based on sales figures and reports I have seen. I have seen what is listed at the UKMIX Forum.
