assumed to be "at least" 26 percent, since this was the proportion 

 obtained from data pertaining to the general population of the United 

 States. 



Applying this proportion to the estimated school-age Navaho popu- 

 lation for the year 1945-46 produced an estimated total Navaho 

 population of over 82,000.*® At the other extreme, the proportions 

 aged 5 to 9, 10 to 14, and 15 to 19 as reported in the Human Dependency 

 Survey of 1936-38 were summed, giving a percentage of 40.6 for the 

 age group 5 to 19, inclusive. As a further check of this figure, a

-Enrolled Navaho populations for selected agencies, bands, and 

 periods— 1880-19^8 ' 



1 The percentages given for each sex at all ages are based upon the total population. The percentages 

 given for the school-age population, both sexes, male, and female, are based upon the total population in 

 each of these categories. In order to minimize the effects of possible variations due to the very small fre- 

 quencies involved, I compiled a series of "synthetic" totals by summing the figures given into 4-year 

 groups. The first of these groups is the sum of the frequencies reported for the years 1880, 1881, 1882, and 

 1883. The second group is the sum of the values given for the years 1885, 1886, 1887, and 1888, etc. The to- 

 tals shown for the longer timespans are merely tlie sum of their component 4-year groupings. The average 

 Ramah population during any one of these 4-year periods would approximate one-fourth of the figures given 

 in this table for tliat period.

8 The data on the Ramah Navaho community were supplied by Dr. David F. Aberle, of the University 

 of Oregon, with the kind permission of the late Prof. Clyde Kluckhohn of Harvard University. The data 

 were compiled from photostats, in the possession of Dr. Aberle, showing single-year distributions, by sex, 

 for the Ramah Navaho as of January 1 of each year from 1880 to 1948. 



^8 From an unpublished report on "Navajo Population" in the files of Robert W. Young, 

 assistant to the general superintendent of the Navajo Agency at Window Rock. This high 

 figure was recognized as an overestimate, and was evidently calculated to illustrate the 

 range of population estimates that could be derived from different assumptions regarding 

 the number and proportion of school-age Navahos.
