The process of population shift from rural to urban areas, coupled with the increasing concentration of residents in relatively dense settlements, is a key demographic trend studied in AP Human Geography. It encompasses not only the physical growth of cities but also the social, economic, and political changes that accompany this transformation. For example, the rapid growth of megacities in developing countries, such as Lagos, Nigeria, exemplifies this trend, highlighting the challenges and opportunities associated with increasing urban populations.
Understanding this process is crucial for comprehending global patterns of development, resource allocation, and environmental change. It influences infrastructure development, economic opportunities, social structures, and the demand for resources like water, energy, and housing. Historically, it has been driven by factors such as industrialization, agricultural advancements, and migration patterns, each contributing to the evolution of urban landscapes and the experiences of their inhabitants. Studying its historical context provides valuable insight to understanding current issues in urban areas.
