and girls who go to work at the earliest ages. Their nearest 

 competitors are the Italians, but they are only half as 

 numerous, forming 18.3% of the total. The native-born of 

 native parentage form the third group with 16.1% of the 

 total. They are followed by the British, the Germans and the 

 Slavs in the order named. 



The sex distribution, although brought out in the foregoing 

 table, is indicated more clearly below. Table 12 indicates the 

 percentage of each sex among the children of the various 

 nationalities 



TABLE 12 



Percentage of Boys and Girls in Each 

 Nationality or Race Stock 



The English, Scotch and Irish evidently send the highest 

 proportion of boys to work; they show 61.0% of boys, and only 

 39.0% of girls. Next come the native-born of native parentage, 

 of whom 57.4% are boys. Germans, Jews and Slavs then fol- 

 low each other in succession. In no case does the proportion 

 of boys vary greatly from the average, which is 53.7%. It is 

 only among Italians that we find the relationship reversed, so 

 that the girls are in the majority, constituting 52.4% of the 

 total number of applicants. 



Table 13 indicates the average height and weight by na- 

 tionality, and by half-year age- periods:
