Urban population refers to the number of people living in cities and towns. This field of research explores various aspects of urbanization, including population growth, migration patterns, housing, infrastructure, social services, and economic development in urban areas. Researchers in this area analyze trends and patterns in urban population dynamics, as well as the impacts of urbanization on society, the environment, and overall quality of life. The study of urban population is important for policymakers, urban planners, and researchers to understand the challenges and opportunities associated with rapid urban growth and to develop effective strategies for sustainable urban development.
