"Urban" refers to areas characterized by high population density and vast human-made structures, such as buildings, roads, and bridges. These areas are typically associated with cities and towns, where economic, social, and cultural activities are concentrated. Urban environments often provide various services, including education, healthcare, and entertainment, making them hubs of opportunity and innovation. Urbanization is the process through which rural areas transform into urban ones, often driven by migration and economic development. This shift can lead to challenges, such as overcrowding and pollution, but it also fosters diversity and cultural exchange. Key aspects of urban life include public transportation, housing, and infrastructure, which are essential for supporting large populations.
