Answer:
New England (which forms a part of North America) developed as an industrial economy by the mid-19th century.
New England was the first to witness industrialization between late 18th and early 19th century. Industrialization began with the establishment of several large textile mills, mainly in Massachusetts and Rhode Island.
New England, especially Massachusetts, was central to industrialization and hence, developed more of an industrial economy.
After New England, the western region of united states experienced industrialization and paved its way to become an industrial economy.
