Highly Urbanized Areas (HUAs) are regions characterized by a significant concentration of population, infrastructure, and economic activity, typically defined as having a high percentage of urban population in relation to their overall population. These areas often serve as central hubs for commerce, culture, and services, playing a crucial role in shaping social and economic dynamics. As countries progress through different stages of development, the emergence of HUAs becomes more pronounced, reflecting shifts in demographic patterns as communities transition from rural to urban living.
