National Immigration. 

 Studies on the eugenical aspect of immigration were continued in collabora- 

 tion with the Committee on Immigration and Naturalization of the House of 

 Representatives and the Department of Labor of the United States Govern- 

 ment. On November 21, 1922, the results of the studies up to that date, 

 with particular reference to the relation between social inadequacy and mod- 

 ern immigration, classified according to race and specific type of disorder, 

 were laid before the House Committee on Immigration. These were pub- 

 lished under the title, "Analysis of America's modern melting pot" (pp. 725 

 to 830 of the hearings before the Committee on Immigration and Naturaliza- 

 tion, House of Representatives, sixty-seventh Congress, third session, serial 

 7-C). These hearings comprise an analysis of the detailed diagnostic and 

 racial returns from 445 State and Federal institutions for the socially inade- 

 quate classes. In these institutions which collaborated in the study were 

 found a total of 210,835 inmates (date of returns being from January 1, 1921, 

 to March 31, 1922). The particular classes studied were as follows: 



The feeble-minded, all types; the feeble-minded, the moron group; the insane, all types; 

 also the dementia praecox group; the manic depressive group; the senile psychosis group; 

 the criminalistic, all types; the criminalistic juvenile group and adult group; the epileptic; 

 the inebriate; the tuberculous; the blind (including the "blind and deaf"); the deaf; the 

 deformed ; the dependent, all types, children and adults ; all classes of the socially inadequate 

 as a unit; the feeble-minded (census of 1920, survey of 1921) and the insane, all types 

 (census of 1920, survey of 1921). 



The analysis was made on the basis of quota fulfillment; each nation and 

 nativity group was allotted an expected quota for each type of degeneracy, 

 based upon the total relative numbers of persons of the particular racial or 

 nativity group in the whole country according to the census of 1910. The 

 quota fulfillment shows a comparison between the number of persons expected 

 and the number found in State and Federal custodial institutions. 



The results logically deducible from this particular investigation show 

 that in reference to nervous stability and social adjustment the immigrants 

 who represent the present foreign-born population of the United States are 

 much more poorly equipped, mentally and physiologically, than the immi- 

 grants whose blood is to-day represented by the group "Native White, both 

 parents native-born." Further, the immigrant himself is better individually 

 than the germ-plasm which he carries and from which his children develop. 

 This shows particularly in the case of the feeble-minded, who themselves, 

 while legally being entirely excludable, showed a quota fulfillment of 21,56 

 per cent^l.25, while the native white, both parents foreign-born, show a 

 quota fulfillment of 165.39 per cent=±=1.34. The native white, one parent 

 native, one foreign-born, show a quota fulfillment of 190.27 per cent ±2.05. 



Representing the House Committee on Immigration as expert eugenics 

 agent, and the United States Department of Labor as special immigration 

 agent to Europe, Dr. Laughlin sailed for Europe August 8 to make studies in 

 several of the European countries on the possibility of determining, in the 

 home towns and the ports of departure, the facts concerning the hereditary 

 qualities and social values of would-be immigrants, and to determine, further, 

 the probable cost to the United States Government, per would-be immigrant, 

 of such practice, should it be enacted into law. 



During the spring and early summer of 1923, Mr. A. E. Hamilton, formerly 

 associated with the Eugenics Record Office, made studies on immigration in
