20 C.F.R. § 641.360
The two documents address some of the same areas, but are prepared at different points in time. The equitable distribution report is prepared by State grantees at the beginning of each fiscal year and provides a "snapshot" of the actual distribution of all of the authorized positions within the State, grantee-by-grantee, and the optimum number of participant positions in each designated area based on the latest available Census or other reliable data. The State Plan is prepared by the Governor, or the highest government official, and covers many areas in addition to equitable distribution, as discussed in § 641.325 , and sets forth a proposed plan for distribution of authorized positions in the State. Any distribution or redistribution of positions made as a result of a State Plan proposal will be reflected in the next equitable distribution report, which then forms the basis for the proposed distribution in the next State Plan update. This process is iterative in that it moves the authorized positions from overserved areas to underserved areas over a period of time.
