[edit] Standard Federal Regions

The ten standard Federal Regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions," in April, 1974, and required for all executive agencies. In recent years, some agencies have tailored their field structures to meet program needs and facilitate interaction with local, state and regional counterparts. The OMB must still approve any departures, however.

[edit] Grand Divisions

Each of the regions below is legally defined as a "Grand Division", with boundaries entrenched in the state's constitution. The document also has rules restricting geographic bias in the makeup of many state commissions. For example, the state's Supreme Court is required to sit in each of the three Grand Divisions each year, and no more than two of the Court's five Justices may reside in any one Grand Division.
