Final answer:
The least accurate statement about nonagricultural slave laborers is that they were primarily found in the Southern colonies, as they also worked in diverse industries in the Northern colonies and contributed to economic growth.
Step-by-step explanation:
The statement about nonagricultural slave laborers that is the least accurate is that they were primarily found in the Southern colonies. While the majority of enslaved people labored in agricultural sectors such as cotton and sugar plantations in the Caribbean and Brazil, nonagricultural slave laborers were also employed in diverse industries, particularly in the Northern colonies. There, they contributed skilled labor to shipbuilding, carpentry, printing, tailoring, shoemaking, blacksmithing, baking, and weaving.
These diverse forms of labor contributed significantly to the economic growth of the regions. In the North, slaves sometimes worked side by side with their masters or were so skilled in their crafts that they competed with free labor. These facts indicate that slaves were not solely found working in the South, but also in northern urban areas, contributing to various industries.
