答案 The Development of World Urban Population This chart cited from the UN report reviews the rapid change of urban population in the 20th century. It demonstrates that there has been a sharp increase in the population of urban areas from 13% in 1900 to 49% in 2005. It is predicted that the population will amount to 60% in 2030. There are several factors leading to the rapid development of urban population in the world. Firstly, with the development of economy, many industries have boomed, attracting more skillful workers and employees to the urban areas. Secondly, with the migrant workers pouring into cities, the structure of the population has been changed greatly. Thirdly, the industrialization of the rural areas also contributes a lot to the increase of urban population. With the development of science and technology, the city will be developed at a relatively high speed. And with the increasing pace of industrialization both in the city and the countryside, the urban population will absolutely become larger and larger.
