The states comprising the Union in 1860 accounted for $175 million in exports in 1860, mostly farm products and manufactured goods.

198,389,351 from the South.

78,217,202 from the North.

276,606,553 total for both.

198,389,351 divided by 276,606,553 = 0.717225781

Add in the portion of Northern exports fed by Southern material sent to the North, and it goes over 73%.

The states comprising the CSA in 1860 accounted for $225 in exports, much of it cotton.

That’s 56.25%.

71.26 % at least. Check my math above.
