Urbanization: The process by which a population becomes increasingly concentrated in urban areas, leading to the growth of cities and the transformation of social, economic, and cultural structures.
Push-Pull Factors: The combination of factors that drive people to leave rural areas (push factors) and attract them to urban areas (pull factors), such as lack of economic opportunities, access to education, and availability of jobs.
Informal Settlements: Unplanned, unauthorized, and often overcrowded residential areas that develop in urban centers as a result of rural-urban migration, where migrants may lack access to basic services and infrastructure.
