White] THE PUEBLO OF SIA, NEW MEXICO 41 
The percentage of the population under 20 years of age in Sia and 
in neighboring pueblos for 1930 and 1957 is shown in table 3. Data 
for 1930 are from “Survey of Conditions of the Indians in the United 
States” (U.S. Sen., 1932, pt. 19); figures for 1957 are from a Program 
Analysis of the U.S. Public Health Service, July, 1957 (their esti- 
mate for Sia’s population is 345 which is much less accurate, ] am 
sure, than our careful survey). 
It is apparent that Sia closely resembles her neighbors in these 
_ percentages. Apparent also is the fact that there was a uniform and 
an appreciable increase in percentage of young people in these 
pueblos between 1930 and 1957. ‘The significance of this increase is 
not clear, however. 
Table 4 and figure 7 show a comparison of the population of Sia 
(1957) by age groups with that of the State of New Mexico (1950). 
The percentages of the younger age groups in Sia exceed those of New 
Mexico up to age 25, after which percentages for Sia are smaller,
