From the above tables, we see that the city of New York, with its neighboring dependencies, will have made in growth in thirty years, between 1830 and 1860, increasing its population 5 times. During the same period, The 5 largest Atlantic cities and suburbs, including New York, increased 4 1-10 times. The 10 largest Atlantic cities and suburbs, including New York, increased 4 " The 15 largest Atlantic cities and suburbs, including New York, increased 3 8-10 " The 20 largest Atlantic cities and suburbs, including New York, increased 3 8-10 " And that the 5 largest cities of the great plain, during the same period, increased 9 " And the 10 largest cities of the great plain, during the same period, increased 10 7-10 " And the 15 largest cities of the great plain, during the same period, increased 10 7-10 " And the 20 largest cities of the great plain, during the same period, increased 10 6-10 " If the number of cities and towns of each section were increased to twenty-five, thirty, and thirty-five of each section, the disparity would increase in favor of the interior cities, most of these to be brought into comparison, having come into existence since 1830. We commend the comparison between the old and the new cities so far back as 1830, to give the former a better chance for a fair showing. If a later census should be chosen for a starting point, the advantages would be more decidedly with the interior cities.
