THE POPULATION OF THE UNITED STATES

outline: map to show the density op population op the united states: the 



number op inhabitants per square mite 



contained 28 per cent of the total popu- 

 lation, while in 1910 they contained not 

 less than 31 per cent. Of the total in- 

 crease in population, 46 per cent was in 

 these cities and 54 per cent in the re- 

 mainder of the country. 



THE MANUFACTURING STATES 



In a general way we may, on the basis 

 of the last column of the table on page 

 36, classify the States as urban and 

 rural, or by their prevailing industries,, 

 as manufacturing and commercial on the 

 one hand and agricultural on the other. 

 The criterion is not a perfect one, as the 

 minimum of city population, 25,000, is 

 too high. If urban centers down to 

 2,500 inhabitants were included, the re- 

 sults might, in certain cases, be different. 

 Moreover, in measuring the ruling in- 

 dustry of a State by the relative magni- 

 tude of its city population, we find in 

 several cases that a single city induces 

 the result. Thus, Illinois as a whole is a 

 manufacturing State; i. e., nearly half 

 its people are in cities, engaged in those 



avocations carried on only in such com- 

 munities ; but, outside of Chicago, Illi- 

 nois is distinctly a farming community. 

 The same is the case in Maryland outside 

 of Baltimore, and Delaware outside of 

 Wilmington. 



Drawing the line at a little below 40 

 per cent of urban population, so as to 

 include Pennsylvania and Ohio, both 

 well known as predominantly manufac- 

 turing States, we may make the following 

 classifications : 



Manufacturing and Commercial States: 

 Massachusetts, Rhode Island, Connecti- 

 cut, New York, New Jersey, Pennsyl- 

 vania, Delaware, Maryland, District of 

 Columbia, Ohio, Illinois, California, 

 Washington. 



Agricultural States: Maine, New 

 Hampshire, Vermont, Virginia, West 

 Virginia, North Carolina, South Caro- 

 lina, Georgia, Elorida, Alabama, Missis- 

 sippi, Louisiana, Texas, Arkansas, Okla- 

 homa, Tennessee, Kentucky, Indiana, 

 Michigan, Wisconsin, Minnesota, Iowa, 

 Missouri, North Dakota, South Dakota,
