JENKS— ETHNIC AMALGAMATION 



Exactly the same story of fecundity decreased by amalgamation is 

 told by the data in Table C as is told by the preceding tables. Each 

 half-breed group is less fecund than its nearest related pure-bred 

 group. 



The fourth column in each half of the table, presenting the aver- 

 age number of married years of the mothers (to the age of 42) per 

 child born, shows more conclusively than Table B that more married 

 years are required per child in the half-breed families than in the pure- 

 bred families.

Lake Benton furnishes us 12 families farther along in the amalga- 

 mation process than the half-breed family. They are families whose 

 two heads are themselves half-breeds, or quarter-breeds, etc. Those 

 families average 1.91 children. This is one child for each 6.91 married 

 years. This is a longer period of time than is required by any of the 

 pure-bred groups, and longer even than is required by any of the 

 half-breed groups in Table C, except the Irish. 



Table D, entitled "Ethnic Amalgamation versus Ethnic Cohesion 

 in Minneapolis," brings the results of a study of the antagonistic 

 forces of cohesion and amalgamation in eight large ethnic groups in 

 Minneapolis. 



Ethnic cohesion is a complex of conditions resulting in the ten- 

 dency of men and women of the same ethnic group to marry. Ethnic
