Migration trends refer to the patterns and movements of people from one place to another, often driven by economic, social, political, or environmental factors. In the context of the growth of cities like Atlanta during industrialization, these trends reflect how populations shifted towards urban areas in search of better job opportunities, improved living conditions, and a chance for upward mobility. Understanding these migration trends helps to grasp how industrialization not only shaped the economy but also transformed the demographics and culture of the regions involved.
