Final answer:
In the 1760s, around 350,000 enslaved blacks were present in the US, but specific annual importation figures for that decade are not provided. The broader Transatlantic Slave Trade brought an estimated 500,000 to the United States over a period of 200 years.
Step-by-step explanation:
By the 1760s, slavery was firmly established in the United States and was essential to the economy. During this period, approximately 350,000 enslaved blacks lived in the colonies, with significant populations in Virginia, Maryland, South Carolina, Georgia, as well as in the northern colonies such as New York and New Jersey. However, specific data regarding the annual number of slaves entering the US every year during the 1760s is not provided in the reference information.
For a broader context, it is worth noting that the Transatlantic Slave Trade transported between 9.6 to 11 million Africans to the New World, though the United States received around 500,000 of those over the span of 200 years from 1600 to 1800. By 1800, though, the annual numbers had drastically declined due to a variety of complex reasons including changing laws, resistance, and economic shifts.In the 1760s, around 350,000 enslaved blacks were present in the US, but specific annual importation figures for that decade are not provided.
