Subject to subsection (c), the amount of a requirements payment made to a State for a year shall be equal to the product of—
(1) the total amount appropriated for requirements payments for the year pursuant to the authorization under section 21007 of this title; and
(2) the State allocation percentage for the State (as determined under subsection (b)).
The “State allocation percentage” for a State is the amount (expressed as a percentage) equal to the quotient of—
(1) the voting age population of the State (as reported in the most recent decennial census); and
(2) the total voting age population of all States (as reported in the most recent decennial census).
The amount of a requirements payment made to a State for a year may not be less than—
(1) in the case of any of the several States or the District of Columbia, one-half of 1 percent of the total amount appropriated for requirements payments for the year under section 21007 of this title; or
(2) in the case of the Commonwealth of Puerto Rico, Guam, American Samoa, or the United States Virgin Islands, one-tenth of 1 percent of such total amount.
The Administrator [1] shall make such pro rata reductions to the allocations determined under subsection (a) as are necessary to comply with the requirements of subsection (c).
A requirements payment made to a State under this subpart shall be available to the State without fiscal year limitation.
