This document discusses urban problems in large cities of developed countries. As people moved from rural areas to cities for jobs and improved standards of living, urban populations rapidly increased. This growth led to issues like crime, homelessness, traffic congestion, high housing costs, and environmental pollution in city centers. Outer suburbs faced problems like expensive commuting and crime. Inner cities struggled with racial tensions, unemployment as factories closed, poor housing, and a lack of amenities and services. The rural-urban fringe also saw crime and expensive housing. These economic, social, environmental, and housing stresses created cycles of poverty that governments and communities worked to overcome.
