No, you didn't use the 91% number, but you repeatedly cited the $331 million-south/$31 million-north import numbers. Arriving at 91% is just math.
Then, when it's considered that the north had four times the population, the per capita consumption of imported goods in the south, becomes roughly 40x that of the north.
You also cited the 1860 Treasury report from the State of the Union address as the source for the numbers, giving a general link and telling us to go find it ourselves. Well, we did find it, only to discover that those numbers were nowhere in that document. Nor could they be extrapolated through any amount of interpretation and study, as you suggest. No, the closest that document comes is in giving the total collected tariffs for each quarter of the preceding year. So why did you tell us all that was the place we could find the numbers?
"You also cited the 1860 Treasury report from the State of the Union address as the source for the numbers,"
I did, and it gave you the import number to begin. I told you that it would take some work.
"giving a general link and telling us"
The link was specific, and I told Grand Old the topic to search for.
"Well, we did find it, only to discover that those numbers were nowhere in that document."
The import/export and tariff data were and are all there.
"Nor could they be extrapolated through any amount of interpretation and study, as you suggest."
It can and does with the right study.
"No, the closest that document comes is in giving the total collected tariffs for each quarter of the preceding year. So why did you tell us all that was the place we could find the numbers?"
Tell us all? Who are you representing?
I told you the source of the data on import value. I told you that the value of import consumption could be determined. I have even explained it to you in a post above.
You still don't get the point do you?
