The quantities in this chart are ICv2 estimates of initial raw orders to Diamond North America on titles scheduled for shipment in August 2002.  They do not include orders placed with Diamond UK, late orders, advance reorders, distributor over-orders, or reorders. 

Marvel, DC, Dark Horse and Image distribute 100% of their comic store orders through Diamond.  Some other publishers distribute directly to stores or through other distributors and as a result this analysis may underestimate their sales. 

Marvel, DC, Dark Horse, and Image distribute some of their titles through channels other than comic specialty stores, e.g., newsstands and bookstores.  These quantity estimates do not reflect distribution through those channels. 

The quantities above do not include advance reorders, late orders, or reorders.

Most of the titles on this chart are also distributed to Europe by Diamond UK, which can account for significant sales for the publisher, ranging from 3-20% of the US numbers.   Sales by Diamond UK are not included in the numbers above.

Even given the above, however, it is probably safe to say that these quantities reflect 80% or more of the total North American sales by the publisher on most periodical comics.   

One other factor to consider is that sales through Diamond and other comic distributors are non-returnable to retailers.  That means that there is a considerable unknown percentage of books unsold at the retailer level.  If that percentage is 10-20% of sales (a reasonable assumption), the estimates above may be quite close to actual sales to consumers.
