Another notable fact brought out by the thirteenth census was that the growth of the cities was greater than during the preceding ten years. The rate of growth of the medium-sized cities was more rapid than that of the large cities. This was not the case during the preceding decade. Of the total population of continental United States, 46.3 per cent were urban. That is, 42,623,383 of the inhabitants resided in cities and towns having a population of 2,500 or more. The same territory in 1900 and 1890, similarly classified as urban, contained 40.5 and 36.1 per cent, respectively, of the total population of the country. In all but two States, Montana and Wyoming, the urban population has increased faster than the rural population. The increase, since 1900, in the population living in urban territory was 11,035,841 or 34.9 per cent, while the increase in population living in rural territory during the same period was 4,941,850 or 11.1 per cent. For the United States as a whole, therefore, the rate of increase for the population of urban areas was three times that for the population living in rural territory. In the States of the east north-central division, including Ohio, Indiana, Illinois, Michigan, Wisconsin, the urban gain was 31.2 per cent, but there was a decrease in rural population of 0.2 per cent. The urban increase of Illinois was 31.2 per cent, but the rural territory of the State showed a loss of 7.5 per cent. The rural loss in Indiana was 5.5 per cent, and in Ohio 1.3 per cent. Michigan's rural gain was 2 per cent and Wisconsin's 5.7. per cent. There were fourteen States in which more than one-half of the population in 1910 were living in urban territory. Among these States were Massachusetts, Rhode Island, and Connecticut with nine-tenths of their population urban; Illinois with 62 per cent, and Ohio with 56 per cent.

The longitude is approximately: 1790, 76.2; 1800, 77.0; 1810, 77.6; 1820, 78.6; 1830, 79.3; 1840, 80.4; 1850, 81.3; 1860, 82.8; 1870 83.7; 1880, 84.7; 1890, 85.5; 1900, 85.8; 1910, 86.5 ] The rapid growth of our industrial and manufacturing interests during the past quarter of a century is shown by the fact that 22 per cent of the people of the country are massed in cities of 100,000 inhabitants and over. In the three largest cities alone--New York, Chicago, and Philadelphia--there are almost one-tenth the population of the whole country. There were five cities with populations between 500,000 and 1,000,000; eleven between 250,000 and 500,000; 31 between 100,000 and 250,000; 59 between 50,000 and 100,000; 120 between 25,000 and 50,000; 374 between 10,000 and 20,000; 629 between 5,000 and 10,000, and 1,173 between 2,500 and 5,000.
