Industrial cities are urban areas that primarily focus on manufacturing and production. These cities often developed during the Industrial Revolution, when advancements in technology led to the establishment of factories. As a result, they typically feature a high concentration of industries, such as textiles, steel, and machinery, which provide jobs for many residents. The growth of industrial cities has significant impacts on their economies and populations. They attract workers from rural areas seeking employment, leading to urbanization. However, this rapid growth can also result in challenges, such as pollution and inadequate infrastructure, which cities like Detroit and Pittsburgh have faced over the years.
