Final answer:
The highest proportion of enslaved workers in North America were in the Deep South, particularly in states like Alabama, Louisiana, Mississippi, and South Carolina. New Orleans was significant, housing the country's largest slave market.
Step-by-step explanation:
The highest proportion of enslaved workers in North America primarily resided in the Southern states of the United States, especially in parts of the Deep South including Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina, and Texas. These states had a high demand for labor due to the plantation agriculture which focused mainly on cash crops such as tobacco, rice, and cotton.
The city of New Orleans housed the largest slave market in the country, where enslaved people, brought from regions both East and West, were sold for work. Despite the presence of a substantial free Black population in the antebellum South, slavery remained deeply entrenched and dictated the economic dynamics of these regions.
