25 This is not an official estimate of the Navaho Indian population. It was obtained 

 from a run of IBM cards prepared by the Branch of Education of the Navajo Agency. 

 The original data were collected by the school censuses conducted during the late 1950's. 

 Although these data were checked and family numbers assigned by the subagency officials 

 before transcription onto IBM cards, the resultant count is still regarded as deficient in 

 certain respects. First, families with no minor children present would be more likely 

 to be omitted in a school census whose major purpose is to enumerate children of school 

 age. Second, the listings include some members of other tribes and a few non-Indians 

 whose membership in an Indian family entitles them to Government services. Third, the 

 listings were originally prepared by the several school districts, so that a certain amount 

 of duplication was inevitable, given the high mobility of the population. Finally, these 

 school census data have not yet been reconciled or coordinated systematically with the 

 several other listings of Navajo population, notably the Navajo Tribal Roll. Although 

 these IBM card counts have not been granted the authenticity of an official population 

 estimate, the work of verifying the listings of the school censuses, eliminating duplica- 

 tions, separately identifying Navajos, and improving the coverage has progressed to the 

 point where these counts furnish information of considerable administrative value. (From 

 communications received from Robert W. Young. Tribal Relations Officer, Gallup Area 

 Office, Bureau of Indian Affairs, and from William H. Kelly, Director, Bureau of Ethnic 

 Research, University of Arizona.)

1 The age distributions from which these ratios were derived are shown In table 31, p. 156. The source 

 of each distribution is indicated in the footnotes to that table. 



2 The "child-woman ratio" is the number of children under 5 years of age per 1 ,000 women aged 15 to 49 

 years. This measure serves as a convenient index of the recent fertihty experience of a population. 



3 The "infant-child ratio" is the number of infants (children under 1 year) per 100 children under 5 years 

 of age. This measure is introduced here as an indicator of the degree of underregistration of births. In 

 a population experiencing substantial infant mortality, but with no appreciable underregistration of births, 

 this ratio should be somewhat in excess of 20 percent, assuming accurate age reporting. 



The number of infants given for the population of Navahos at the Fort Defiance Agency in 1915 is 

 estimated by me on the basis of the single-year age distribution obtained from an approximate 10 per- 

 cent sample of the original roll. This sample produced a total of 214 children under 5, of whom 31 were 

 under 1 year of age. Applying the ratio of 31 to 214 to the reported number of 2,585 children under 5 

 produces the estimated numlDer of infants as 374. 



* The number of infants was not reported for this population. 



5 Estimated from the proportion of persons under 5 years of age who were reported to be under 1 year of 

 age among Indians on the Navajo Reservation in 1960. These data actually pertain to all non- Whites of 

 enumeration districts falling within the boundaries of the Navajo Reservation.
