Now you [BroJoeK] may ask why '64 and '65 data is at some variance. Reason being is that Census/Customs data was published at the end of the callendar year. Treasury data was compiled and published on a June 30/July 1 schedule.

I read something the other day on why tariff revenue jumped up in 1864. The reason given was that importers removed items from the warehouses in advance of an impending higher tariff rate.

Regardless, the data clearly shows the Union economy and Federal tariff revenues were not as dependent on Deep South cotton as some have claimed.
