NATIONAL ORIGINS PROVISION OF IMMIGRATION LAW 
Senator Reep. You are also secretary of the quota board, are you 
not? 
Mr. Bogas. Yes, sir. 
Senator Rep. That is the board created by the immigration law 
for the ascertainment of these quotas? 
Mr. Boges. Yes, sir; the committee of six. 
Senator Rerp. Have you been secretary of that board constantly 
since its organization ? 
Mr. Boas. Since its active work was begun on the national-origins 
quotas about three years ago. 
Senator Reep. Mr. Boggs, do you consider the national-origins 
methods and the 1890 foreign-born method so that you are able to 
make a comparison between the two of them from the standpoint 
of accuracy? 
Mr. Boges. I would not want to say anything that would discredit 
the present quota system in itself. Buf I have had to study the 
present quotas in order to gather such information as they had 
utilized, and to learn anything I could from their processes, in order 
to get a good start on the work of determining the national-origin 
uotas. 
4 The national-origins quotas have, as we have used them, four sepa- 
rate factors: First, the immigration, that is, the foreign-born, re- 
ported in the 1920 census in the terms of postwar geography; sec- 
ond, the children of foreign-born who are reported interms of pre- 
war geography; that is, the countries from which their immigrant 
parents came; and then, for statistical convenience and practical 
necessity, as I think Doctor Hill has previously explained, we have 
utilized figures concerning, third, the colonial stock, and fourth, the 
oe stock other than the foreign born and the children of 
oreign born. So that we have four streams. 
The immigrants, and children of foreign-born immigrants—— 
Senator Corer.axp. Pardon me just a moment. Those four streams 
represent the colonial stock and the immigrants? 
Mr. Boees. The postcolonial stock, which we have also called the 
“immigrant stock,” comprises what we call the grandchildren and 
later generations of postcolonial stock, the children of foreign born, 
and the foreign born themselves. That is simply for statistical con- 
venience. 
Senator Remp. Take the first of those streams, the foreign born, 
is there any element of uncertainty in that? 
Mr. Boges. There is practically none, because it is reported in 
terms of post-war geography and it is in itself, of course, much more 
usable than are the 1890 foreign-born statistics in determining the 
present quotas, because it is in terms of post-war geography, whereas 
the 1890 foreign-born data have to have a good manv adjustments 
made because of the geographic changes. 
The Cmairman. The second of the sources that you used, how is 
it as to accuracy? 
Mr. Bocas. The children of the foreign-born are reported, as I 
say, in terms of pre-war geography, as of necessity, because they 
could not tell the countries, in terms of post-war geography, from 
which their parents came; many would not know of the geographical 
changes in Europe. But we have to use with that statistical table
