The east also benefits from favorable geography. Its abundant rivers and natural harbors made transportation and trade easier, fostering early industrialization. The Midwest, particularly the area around the Great Lakes and Mississippi River, became an agricultural and industrial hub, attracting even more people due to job opportunities. Cities like Chicago and Detroit thrived during the Industrial Revolution.
In contrast, the western regions of the U.S. were more sparsely populated, partly due to the rugged terrain of the rocky Mountains and the arid climate of much of the West. Additionally, the expansion of the railroads and the Homestead Act encouraged further development in the east and Midwest, solidifying the population imbalance. Today, the east Coast remains home to major financial, cultural, and political centers, continuing its legacy as the more and more densely populated region.
