Population schedules in the cities and large towns were required to be completed within two weeks and in the rural districts within thirty days. The enormous labor of tabulating and classifying these answers was then begun by the 3,500 clerks in the Census Office at Washington. Much of this labor was performed by machines each capable of making 25,000 tabulations a day. Results of the first tabulation of the population in the cities were made known about June 1 and the count of the principal cities was completed by April 15. During September the population of the entire country was made known. Within two years the leading facts in the census were compiled and published as special bulletins. The entire cost of the census was about $13,000,000. The total population of the United States, including our territorial possessions and dependencies, was found to be about 101,000,000, thus for the first time passing the hundred million mark. The population of the United States proper was 91,972,266; of Alaska, 64,356; Porto Rico, 1,118,012; Hawaii, 191,909; Guam and Samoa, 15,100; the Philippine Islands about 7,700,000. These numbers indicate an increase in the population of continental United States of 21 per cent in the decade, or a slightly larger growth than the 20.7 per cent made during the preceding ten years. One of the striking facts brought out in the census is the absolute decline in the percentage of population compared with the previous decade in a number of the States of the East, South, and Middle West, and an increase of this percentage in the other States, especially among those of the Rocky Mountains and the Pacific Coast. The percentage of total increase of population in Alabama was 16.9 and the increase, according to the twelfth census, was 20.8; in Illinois, 16.9 as against 26 for the preceding census; Indiana, 7.3 against 14.8; Kentucky, 6.6 against 15.5; Massachusetts, 20 against 25.3; Minnesota, 18.5 against 33.7; Texas, 27.8 against 36.4; Montana, 54.5 against 70. Iowa showed an actual loss of three-tenths per cent of her inhabitants, while according to the preceding census there was a gain of 16.7 per cent in that State. In the following States the gains in percentages were as follows: North Dakota, 80.8 against 67.1 for 1900; South Dakota, 45.4 and 15.2; Kansas, 15 and 3; Nebraska, 11.8 and 0.3; Colorado, 48 and 30.6; Oklahoma, 109.7; Utah, 34.9 and 31.3; Nevada, 93.4 and 10.6; Idaho, 101.3 and 82.7; Washington, 120.4 and 45; Oregon, 62.7 and 30.2, and California, 60.1 and 22.4. In numerical advance, New York, Pennsylvania, California, Texas, and Illinois led. The increase in New York was nearly 2,000,000, in Pennsylvania over 1,000,000, and in the other three States nearly 900,000 each.
