The Office shall allocate 80 per centum of the total amount available for grants under this chapter among the States on a weighted formula taking into consideration such factors as the size of population and the number of State and local government employees affected.

The amount allocated for each State under paragraph (1) of this subsection shall be further allocated by the Office to meet the needs of both the State government and the local governments within the State on a weighted formula taking into consideration such factors as the number of State and local government employees and the amount of State and local government expenditures. The Office shall determine the categories of employees and expenditures to be included or excluded, as the case may be, in the number of employees and amount of expenditures. The minimum allocation for meeting needs of local governments in each State (other than the District of Columbia, the Commonwealth of Puerto Rico, Guam, American Samoa, and the Virgin Islands) shall be 50 per centum of the amount allocated for the State under paragraph (1) of this subsection.

The amount of any allocation under paragraph (2) of this subsection which the Office determines, on the basis of information available to it, will not be used to meet needs for which allocated shall be available for use to meet the needs of the State government or local governments in that State, as the case may be, on such date or dates as the Office may fix.

The amount allocated for any State under paragraph (1) of this subsection which the Office determines, on the basis of information available to it, will not be used shall be available for reallocation by the Office from time to time, on such date or dates as it may fix, among other States with respect to which such a determination has not been made, in accordance with the formula set forth in paragraph (1) of this subsection, but with such amount for any of such other States being reduced to the extent it exceeds the sum the Office estimates said State needs and will be able to use; and the total of such reductions shall be similarly reallocated among the States whose proportionate amounts were not so reduced.

For the purposes of this subsection, “State” means the several States of the United States, the District of Columbia, the Commonwealth of Puerto Rico, Guam, American Samoa, and the Virgin Islands.
