Cities Now Home to More Than Half of All People Over half the world's people now live in The latest "Global Report on Human Settlements" says the historic change took place last The report came out this week from UN Habitat， a United Nations A century ago， less than 5% of all people lived in By the middle of this century it could be 70% ， or almost 6，500，000，000 Already 3/4 of people in developed countries live in Now most urban population growth is in the developing Urbanization can lead to social and economic progress， but also pressure on cities to provide housing and The new report says almost 200，000 people move into cities and towns each It says worsening inequalities， driven by social divisions and differences in wealth， could lead to violence unless cities plan Another issue is urban This is where cities expand into rural areas， sometimes at a much faster rate than urban population Sprawl is common in the United S Americans move a In a recent study， Art Hall at the University of Kansas found that people are moving away from the major cities to smaller He sees a trend toward "de-urbanization" across A But urban economies still provide possibilities that rural areas do 城市人口过半 如今世界过半数人口都居住在城市。据最新一份“全球人居报告”显示，在去年这一情况发生了巨大变化。联合国人居机构在本周发布了这项报告。 一个世纪前，全球城市人口不足5%到本世纪中叶，城市人口可能上升至70%，约有65亿人。发达国家现有四分之三的人口为城市人口。现在，大多数城市人口增长发生在发展中国家。 城市化推动了社会和经济的向前发展，但同时也增加了城市提供住房和服务的压力。据这份最新报告显示，每天约有20万人口向城镇转移。报告也同时指出，除非城市能有更好的规划，否则日益严重的不平等，社会分工以及贫富差距，均有可能导致暴力的发生。 另一个问题就是城市的扩张。城市向乡村地区扩张的速度有时候甚至比城市人口增长速度更为惊人。 这一现象在美国很普遍。美国搬迁的人数众多。卡萨斯州大学的阿特。霍尔在其最新研究中发现，人们正在从大城市搬迁至小城市。他将这称之为美国的“逆城市化”趋势。 但是城市经济仍然可以提供农村地区不能提供的可能性。
