2. (b) Determination of State allotment percentages The “allotment percentage” for any State shall be 100 percent less the State percentage; and the State percentage shall be the percentage which bears the same ratio to 50 percent as the per capita income of such State bears to the per capita income of the United States; except that (1) the allotment percentage shall in no case be less than 30 percent or more than 70 percent, and (2) the allotment percentage shall be 70 percent in the case of Puerto Rico, the Virgin Islands, Guam, and American Samoa.
