As you can see, all Union slave states were at the very bottom in percentage of slaveownership. All other Union states had zero slaves.
the VAST majority of southerners were TOO POOR to own a slave, even had they wanted to. the TRUTH is that there were relatively FEW slave owners in dixie, but that those who DID own slaves owned MANY. (for example, in my home county in 1860, there were 3 total slavers. one owned one (his WIFE), one had 2 slaves & one had MANY.)
according to the TAX RECORDS the percentage of overall slave-ownership was about 5.75%.
peddle your "statistics" elsewhere. as my grandfather used to say, "figure don't lie, but liars sure figure."
