IMM/GRA TION AND CRIME 377
North Atlantic Division is seen be to 24,883 ; the number of whites, foreign born, shown by column 9, is 7307. Adding the Chinese and Japanese in columns 15 and 16, the total number of foreign-born prisoners is 7322; deducting from the aggregate in column I, we have 17,561 native born. By reference to column 7, the number of natives having both parents foreign is seen to be 7006, leaving 10,555 native born of native parents.
Dividing the total number of male prisoners (24,883) by the total number of male inhabitants of voting age (5,055,239), we obtain .4920 as the ratio to a million, as shown in column i of the table.
The ratios for each class and for each state are obtained in the same way. The number of males of voting age and the number of prisoners for the " Northern States" is obtained by adding the "North Atlantic," "North Cen- tral," and "Western" Divisions.
