How New York Became America’ Largest City
In the 18th century New York was smaller than Philadelphia and Boston. Today it is the largest city in America. How can the change in its size and importance be explained?
To answer this question we must consider certain facts about geography, history, and economics. Together these three will explain the huge growth of America’s most famous city.
The map of the Northeast shows that the four areas with the largest populations in this region are around seaports. At these points materials from across the sea enter the United States, and the procts of the land are sent there for export across the sea.
We know that places where transportation lines meet are good places for making raw materials into finished goods. That is why seaports often have cities nearby. But cities like New York needed more than their geographical location in order to become great instrial centers.
About 1815, when many Americans from the east had already moved toward the west, transportation routes from the seaports to the central regions of the country began to be a serious problem. The slow wagons of that time, usually draw by horses, were too expensive for moving
heavy freight very far. ①In New York a canal seemed the best answer to the transportation problem. From the eastern end of Lake Erie all the way across the state to the Hudson River there is a long strip of low land. Here the Erie Canal was built. After several years of work it was completed in 1825.
The canal proced an immediate effect. Freight costs were cut to about one tenth of what they had been. New York City, which had been smaller than Philadelphia and Boston, quickly became the leading city of the coast.
The coming of the railroads made canal shipping less important, but it tied New York even more closely to the central regions of the country. It was easier for people in the central states to ship their goods to New York for export overseas.
Exports from New York were greater than imports. ②As a result, shipping companies made every effort to fill their ships with passengers on the return trip from Europe. And so passenger could come from Europe very cheaply.
Thus New York became the greatest port for receiving people from European countries. Many of these people remained in the city. For these great numbers of new Americans New York had to provide homes, goods and other things. Their labor helped the city become grea
