Cook County is divided into 15 subcircuits for the purpose of electing subcircuit judges. Three subcircuits are located entirely within the City of Chicago (subcircuits 5, 6, & 8) and four subcircuits are located entirely in the County outside of the corporate limits of the City of Chicago (4, 12, 13, & 15). Eight subcircuits have territory in both the City of Chicago and the outer County (1, 2, 3, 7, 9, 10, 11, & 14). These eight subcircuits have two maps, one for the territory inside the City and one for the area in the outer county region.

The boundary descriptions explain the outside border of each subcircuit, beginning in the northwest “corner” of the district and proceeding clockwise. The boundaries are described by streets and identifying lines. The maps appear first, followed by the legal descriptions.
