2. Midwest: The Midwest region, particularly states like Ohio, Illinois, and Michigan, saw significant growth as fertile farmlands attracted settlers, and cities like Chicago became hubs for transportation and manufacturing.
3. West Coast: The discovery of gold in California in 1848 led to a population boom in the West Coast, particularly in California and San Francisco, attracting settlers from all over the world.
4. Southern States: Industrial cities in the South, such as Atlanta and Birmingham, grew rapidly as centers for textile mills, iron production, and other industries.
