Where have many large cities sprung up according to the conversation? [originalt

W: You’re an expert on urban problem, Mr. Cross. [1] I wonder how you would describe the characteristics of these enormous cities which have sprung up in Asia and Latin America?
M: The first point to make is that they are different from large cities in Europe and America.
W: Surely all large cities are essentially similar.
M: It’s true that in all large cities there are the same problems of provision of housing and services, but the difference lies in the time factor.
W: Surely some of the cities we are considering are just as old and, in some cases, much older, than cities in the United States, for instance.
M: Very true, but the large cities of Europe and the United States grew relatively slowly. [2] London had a population of more than a million at the beginning of the nineteenth century and this number grew for more than a hundred years until it reached its maximum of more than eight million. And this growth was parallel to industrial growth throughout the country. The same is true of New York, for example.
W: But this is not true of Mexico City or Buenos Aries?
M: No, it is not. [3] Throughout Latin America and in parts of Asia, cities have grown much faster than industry, or agriculture for that matter. Some of these cities have quadrupled in size in less than two decades, while industrial growth over the same period may only have reached thirty or forty percent.
