This table breaks exports down by product and by region.
I imagine the table is consistent with tabulations you have found."
Thanks for the highly informative link, but no, not 72%.
Your table shows 1860 exports as:
- Produced in the West: $61 million= 16%
- Produced in the East: $83 million = 22%
- Produced in the South: $229 million = 61%
- Total exports: $373 million
But even that number 61% is suspect, since tobacco is the number two item and it came mostly from Union states, none from the Deep South in 1860.
Other significant items include cotton cloth, which we cannot know the original sources of.
So a slightly more accurate number using this data would be 54% ($204 divided by $373 =54%).
But even that number is too high, since this source (page 605) shows total 1860 exports as not $373 million but $400 million, including specie.
That makes Deep South produced products just 51% at most.
Finally, it's hugely important to notice just what happened in 1861:
- Southern exports fell by over 70%, but nearly all the reduction was in raw cotton.
Other Southern exports held up pretty well, suggesting they really came from Union states, not the Deep South. - Western exports increased by 80% suggesting that outside cotton itself "Southern exports" were highly replaceable from other Union states.
- Eastern exports also increased, slightly, suggesting that whatever Eastern exports came from Southern raw materials were not overly dependent on them.
