THE POPULATION OF THE 

 UNITED STATES IN 1910 



The Bureau of the Census has now 

 issued a bulletin giving the oificial fig- 

 ures of the thirteenth census, prelim- 

 inary statements of which have from 

 time to time been made public. The 

 population of the United States was 

 93,402,151, of which 1,429,885 belongs' 

 to the non-contiguous territory of 

 Alaska, Hawaii and Porto Kieo and 

 persons in the military and naval serv- 

 ice stationed abroad. There are still 

 to be added the inhabitants of the out- 

 lying possessions of the United States 

 — some eight millions — nearly all in the 

 Philippine Islands. The percentage of 

 increase from the preceding census is 

 21, being three tenths of a per cent, 

 larger than for the preceding decade. 

 The population of the United States 

 shows an increase of about one third 

 during each of the seven decades from 

 1790 to 1860, of about one fourth dur- 

 ing the three decades from 1860 to 



1890 and of about one fifth during 

 each of the last two decades. Thus 

 while the increase in population over 

 the preceding census continually in- 

 creases, the percentage of increase be- 

 comes continually less, and there is no 

 reason to suppose that the population 

 will increase indefinitely. Indeed, if it 

 were not for foreign immigrants and 

 their larger families, the increment of 

 increase of the population would he 

 very small. It should, however, be 

 added that there are those who hold 

 that the native population would in- 

 crease more rapidly if it were not for 

 the large immigration. 



The density of population and the 

 increase of population, as shown on the 

 accompanying maps, are very unequally 

 distributed over the United States. 

 There are ten states in which there 

 were in 1910 a population per square 

 mile of more than one hundred. Rhode 

 Island with 508, and Massachusetts 

 with 418 are the most densely popu-
