198 UNIVERSITY OF COLORADO STUDIES 
The above table shows the large number of persons among the popu- 
lation of the West and especially in Colorado of middle and younger ages 
as persons of such ages constitute the element engaged in gainful occu- 
pations. The decline in the percentage for Colorado from 1890 to 
1900 is probably due to the increase in the number of children and also 
to the popularity of Colorado as a health resort and tourist attraction. 
Age distribution is further shown by the fact that of the United 
States Colorado ranks third in percentage of population from 4o to 49 
years, being exceeded only by California and Nevada; fourth in per- 
centage of population 30 to 39 years, being exceeded by Montana, Wyom- 
ing and Washington, and sixth in percentage of population from 15 to 
59 years, being exceeded by District of Columbia, Montana, Wyoming, 
Nevada and California.‘ The large percentage of the population in 
the productive ages is somewhat striking when compared with that of 
the other divisions of the United States as appears from the following 
table.
