What subregions of the US industrialized first?

The northeastern United States, particularly areas like New England and the Mid-Atlantic, industrialized first during the early to mid-19th century. This region benefited from abundant water power, a growing labor force, and access to shipping routes, facilitating the establishment of textile mills and factories. The Great Lakes region also saw significant industrial growth later on, particularly in steel production and manufacturing, as railroads expanded and resources became more accessible.
