Oh, slaves out-numbered whites better than 10 to one ⦠in Haiti.
In the Southern states of the USA, only a small proportion of white families owned slaves, and even then the average ownership was small (about four or five). Those were mainly house servants, and essentially lived very close to their whites.
It is often mentioned that states forbade teaching slaves to read, which is technically true. But in practice, many slaves were at least partly literate, taught by their owners, or sometimes learning by themselves or from other slaves.
Thomas W. Dixon wrote in his autobiography that in old Virginia one of the family servants would go hunting for rabbits, using his own rifle.
