Current version, with additions and removals from the July 5, 1994 version.
(b) State Planning and Research.—(1) Fifty percent of the amounts made available under section 5338(g)(3) of this title shall be apportioned to States for grants and contracts consistent with the purposes of sections 5303–5306, 5312, 5315, 5317, and 5322 of this title. The amounts shall be apportioned so that each State receives an amount equal to the population in urbanized areas in the State, divided by the population in urbanized areas in all States, as shown by the latest available decennial census. However, a State must receive at least .5 percent of the amount apportioned under this subsection.
(2) A State, as the State considers appropriate, may authorize part of the amount made available under this subsection to be used to supplement amounts available under subsection (a) of this section.
(3) An amount apportioned under this subsection—
(A) remains available for 3 years after the fiscal year in which the amount is apportioned; and
(B) that is unobligated at the end of the 3-year period shall be reapportioned among the States for the next fiscal year.
