It is situated to the south of the borough of Dukes and connected to Algonquin by the Broker and Algonquin bridges. Broker was named after King George III's bastard son who came to America. Streets in Broker are been named after Western-era cowboys and cowboy-related words (Cassidy Street, Deadwood Street, Earp Street, Hickock Street, and Kid Street are some examples).

Broker and Dukes are the only boroughs in the metropolitan area that share an island. Waters separate all other boroughs.
Broker's central business district is it's Downtown neighborhood, which is a successful business district beside Outlook Park with tall buildings. Broker is a very poor borough shown in other areas though; around BOABO and Schottler there are many hobos. Near Niko's safehouse in Hove Beach, there are many Russian thugs with weapons hanging around. If Niko exits his safehouse in Hove and shoots the sky, these thugs will be notified and start blasting Niko.
Broker has a very large diversity in the characters of various districts. The western districts (East Hook, BOABO) are gritty, run down and industrial, however in some cases gentrification is common. In other districts, like Outlook, Rotterdam Hill and South Slopes, a diverse, middle-class population of yuppies, immigrants, businesspeople and hipsters resides, There are also districts with their own individual, ethnic minority identities, these include; Eastern European: Hove Beach, African American: Firefly Projects and Jamaican/Caribbean: Schottler & Beechwood City, The borough also offers areas with important uses, such as a business district and urban center: Downtown Broker, Entertainment: Firefly Island and an affluent, gated, residential area for Liberty City's wealthiest: Beachgate.
