responsibility of carrying out the enumeration in their respective 

 reservation areas. 



In order to obtain information on certain characteristics of par- 

 ticular significance to the Indian population, a special schedule (Form 

 MM 3-397) was again prepared. In addition to the 32 items of infor- 

 mation requested from the general population of the United States, 

 this Indian schedule contained 14 additional items. A brief summary 

 of the content of the more pertinent of these items reveals the scope 

 of the decennial census in its coverage of the Indian population at 

 this time. Among the items on the regular schedule were questions 

 relating to the respondent's ability to speak English, or, if unable 

 to do so, what language was spoken ; the person's occupation and in- 

 dustry ; and whether the person was able to read, write, or was cur- 

 rently attending school. The enumeratoi-s were instructed to enter 

 "Kation Indian" in the space provided for the respondent's occupa- 

 tion and industry if tlie Indian in question had no occupation and 

 was wholly dependent upon the Government for svipport. If this 

 dependency was apparently partial, the enumerator was instructed 

 to enter the letter "R" beside the person's reported occupation and 

 industry. 



The 14 additional items also were designed to determine the indi- 

 vidual's tribal affiliation; that of his father and of his mother; his 

 proportions of Wliite, Indian, and Negro blood ; the number of times 

 the Indian had been married; whether he was living in polygyny at 

 the time of the census, and if so, whether his wives were sisters (sororal 

 polygyny). Finally, the Indian schedule included inquiries concern- 

 ing what educational institution, if any, the individual had attended 

 and from which he was graduat-ed ; whether the individual was taxed ; 

 whether he had received an allotment of land ; whether he was residing 

 on his own lands; and whether he was living in a "civilized" or an 

 "aboriginal" dwelling. 



It is evident that the 1910 enumeration was designed to furnish a 

 remarkably comprehensive description of the socioeconomic condition 

 of the Indians, and the degree to which they had been acculturated 

 through contacts with the general society of the nation. 



The general population totals for the Navaho, as returned in this 

 census, are shown in table 23 together with the figures submitted to the 

 Commissioner of Indian Affairs by the Navajo Agency in 1910 and 

 1911. Examination of these figures indicates that the proper discrep- 

 ancy in the total given is to be found in the figures for Arizona, where 

 the 1910 census returned a total of 11,001 Navahos, while the cori-e- 

 sponding number given by the Navajo Agency was 18,150. Dr. Roland 

 B. Dixon, who, together with Dr. F. A. MacKenzie, directed the tabula- 

 tion and analysis of the results of the 1910 Indian enumeration, ex-
