I think the Industrial Revolution led to the rapid growth of cities in the northeastern states because in this region were located the big factories and fabrics that introduced mass production as their form to produce goods.
Many people from the south. who lived in the rural areas of that region, decided to move to the larger cities of the northeast precisely to get a job in the fabrics. Many immigrants came to the United States to work in factories, They came from Europe and Asia. They went to New York or Chicago, and many other cities.
Of course, the population grew and these workers, as they were poor, they had to live in poor overcrowded spaces with no ventilation at all and where disease spread quickly and easily.

The Patriots had more supplies, could get supplies easier, had a home court/familiar territory advantage, and had more motivation. The British had less supplies, had to ship supplies overseas, were unfamiliar with the territory/far from home, and had little motivation. The patriots won because of their surplus in supplies, the British lost because they ran out of supplies.
