76 Heredity and Child Culture 



The following table that I have prepared 

 from data collected by the Federal Children's 

 Bureau will give some idea of the development 

 that was found among a large number of Ameri- 

 can children from two to six years of age.

In a study of nearly 40,000 children of pre- 

 school age in Iowa, it was found that the boys 

 from birth to six years were uniformly taller 

 and heavier at all ages than the girls. It was 

 also noted that the percents of total stature 

 and weight at six years showed that the height 

 doubled in these cases during the first six years 

 after birth and the weight increased four times. 

 The rural Iowa children were above the urban 

 ones in stature and weight from birth to six 

 years.
