CBS Chicago sums it up:
The Prairie District station at 300 E. 29th St. dates from 1952. It serves an oddly-shaped precinct, extending north of Cermak Road and west to the Penn Central railroad tracks to include Chinatown and parts of Bronzeville, then proceeding south down the lakefront east of Cottage Grove Avenue.
At its southern edge, the district borders include the entire Hyde Park neighborhood except for Jackson Park, and extend south to 61st Street between Cottage Grove and Dorchester avenues so as to include the entire U of C campus.
The U of C also has its own private police department, which patrols even farther south into the neighboring Grand Crossing District.
But the Chicago Sun-Times recently pointed out that the nearly 60-year-old station could be merged with the Wentworth District to the west, given that its resources are no longer dominated by crime in the now-demolished Robert Taylor and Stateway Gardens public housing high-rises along the State Street corridor.
Yet, while crime in Hyde Park and around the U of C campus is vastly lower than in many nearby neighborhoods, security is still a concern.
