According to federal census reports, on June 1, 1860 there were nearly 4.5 million Negroes in the United States, with fewer than four million of them living in the southern slaveholding states. Of the blacks residing in the South, 261,988 were not slaves. Of this number, 10,689 lived in New Orleans. The country's leading African American historian,
Duke University professor John Hope Franklin, records that in New Orleans over 3,000 free Negroes owned slaves, or 28 percent of the free Negroes in that city.
To return to the census figures quoted above, this 28 percent is certainly impressive when compared to less than 1.4 percent of all American whites and less than 4.8 percent of southern whites.
The statistics show that, when free, blacks disproportionately became slave masters.
The majority of slaveholders, white and black, owned only one to five slaves. More often than not, and contrary to a century and a half of bullwhips-on-tortured-backs propaganda, black and white masters worked and ate alongside their charges; be it in house, field or workshop. The few individuals who owned 50 or more slaves were confined to the top one percent, and have been defined as slave magnates.
In 1860 there were at least six Negroes in Louisiana who owned 65 or more slaves
