APPENDIX C 



Graduated Numbers of the Male Population of the Continental United 



States, Ages 18-49, by Single Years of Life and Conjugal 



Condition, Estimated for the Year 1918 



NOTE. The actual age returns, by single years of life, according to the Census, 

 include numerous inaccuracies in matters of minor detail. It has therefore seemed 

 advisable to graduate the data in conformity to standardized methods of sta- 

 tistical practice. The combined totals for the three groups, by conjugal condi- 

 tion, varies slightly from the estimated graduated total, but the differences 

 are relatively unimportant. The estimates are, of course, without refer- 

 ence to the effect of the first and second selective drafts, and the mortality of 

 the American forces at home and abroad since the outbreak of the war.
