You might try actually reading the article that started this thread. Benson's claim is that the Southern states "chose to withdraw from a Union for which they were paying 83% of all the expenses, while getting precious little back for it, save insults from the North." In other words, generating 83% of all revenue. When Vigilanteman questions such an outrageous claim you referenced the "Statistical History of the United States". So are you now saying that there is no breakdown of imports by region in there? That the South did not generate 83% of the tariff revenue? That you were, in fact, engaging in non-sequitur all along?
I read the article. You were given the location for the statistics. You understand where the 83% originated.
You asked for the breakdown of imports by region. I will be glad to give you that information. But since the southern states imported both European goods as well as northern domestic manufactures, what will it tell you?
