For urban residents, the rapid population growth undoubtedly brings about a lot of negative impacts. A larger urban population means heavier operational pressure on cities. In most cases,urban development fails to keep pace with this population increase, which lead to numerous problems. For instance, high population density leads to more frequent traffic congestion, competition for high-quality job opportunities becomes increasingly fierce, and urban environmental pollution is aggravated by a large population. All these issues undermine citizens’ quality of life and hinder the sound and sustainable development of cities.
