This document discusses the issues and implications of urbanization. It begins by defining urbanization as the process by which cities grow and higher percentages of populations live in cities. Nearly half of all people now live in urban areas for jobs, education, and entertainment. However, rapid urbanization in developing countries is causing socioeconomic problems like unemployment and poverty due to not enough jobs. It is also causing environmental issues like pollution, flooding, and crime. Politically, urbanization requires better governance and management of resources to deal with these problems. Sustainable development of urban areas will require integration, tackling land use and infrastructure issues, as well as promoting economic growth and green spaces.
