以下是按课堂已讲方向整理的课后复习改进版。课堂重点讲了整体趋势、曼哈顿与其他五区的关系、上升表达、占比变化和开头段改写;具体年份和数字沿用课堂中明确提到的信息,不额外编造原因。
The tables illustrate how the total population of New York City changed over the given period, and how this population was divided between Manhattan and the other five boroughs.
Overall, the city’s population increased sharply across the period. At the same time, the demographic center shifted away from Manhattan and towards the other five boroughs.
In 1800, New York City had a total population of 79,216. More than three quarters of these people lived in Manhattan, while the other five boroughs accounted for a much smaller share.
By 1900, the total population had surged. Manhattan’s population also rose, but its percentage share fell to nearly a half, which means the other five boroughs were becoming much more important in the city’s population structure.
By 2000, the pattern had changed more clearly. Manhattan was no longer the main population center, as a larger share of the city’s residents lived in the other five boroughs.
