Why do cities attract people in the late 19th century

As the 19th century drew to a close, the rapid development of cities served as both a uniting and diving factor in American social, economic, and political life. Cities attracted a rich cross-section of the world’s population, creating a diverse, metropolitan atmosphere. At the same time, cities forced people from entirely different backgrounds to live and work together in close proximity for the first time, which served as a uniting factor. The never-ending influx of immigrants from Germany, Ireland, Britain, and Scandinavia created an ethnically diverse population united by their common financial plight, social oppression, and shared American Dream. Hope this helped you! :3
