According to the in-game Public Broadcasting documentary, Bohan is a Dutch word meaning "Dutch word" (Although this is untrue. The real Dutch word for "Dutch word" is "Nederlands woord"). Most Bohan avenues are named after major prisons, with Alcatraz Avenue, Rykers Avenue, Sing Sing Avenue, San Quentin Avenue, and Guantanamo Ave being five examples, while others are named after breakdancing moves, such as Worm Street, Spin Street, Applejack Street and Valdez Avenue. South Bohan is also advertised in the game as the birthplace of hip-hop.
Bohan's financial state is poor and it is the most deprived of the four boroughs in Liberty City, mainly consisting of run-down housing projects, pockets of small time businesses and stores, abandoned buildings and decrepit warehouses. South Bohan and Fortside are the best examples of this type of location. Whilst there is often evidence of gentrification in other deprived districts across Liberty City, there is very little evidence of it in these neighborhoods with the exception of Northern Gardens. More often than not, Bohan statistically outperforms the other boroughs in crime rate. This is especially alarming when considering that it is also the smallest borough - meaning that the crime would naturally affect more people. Bohan is also home to two different street gangs - the Spanish Lords and the Albanian Mob, as well as one of the five major mafia families in the Commission - the Lupisella Family (though the Lupisella are not physically seen on the streets).
South Bohan and Fortside are large residential areas within southern Bohan , and are very impoverished and full of crime. They primarily consist of apartment complexes, some small-time stores/businesses and abandoned/boarded-up buildings. South Bohan also contains one of the largest housing projects in Liberty City, and the largest in Bohan. There is a strong gang presence in these neighborhoods, with a high level of gang violence in these two districts, with South Bohan and Fortside being Spanish Lords' primary turf.
Chase Point and Bohan Industrial generally consist of abandoned warehouses and archaic docking facilities, serving as Bohan's declining industrial districts. Prostitution is very common in these districts, far more so than anywhere else in Liberty City. Street prostitutes can be found congregating on many street corners during the nighttime. Also, at night, muggers and street thugs will roam freely. Luis Lopez warns Arnaud, after he is mugged, that things can often get rough, and he shouldn't wander around alone.
The police rarely give a concern for any of the crime in Bohan, more prominently than anywhere else, noted when Niko Bellic is able to enter a warehouse and kill a gang of drug dealers, all without any police trouble for Manny Escuela, who was making a documentary about the crime and corruption of the borough. Manny's camera man comments after Niko kills the gang: "More senseless death, and the police aren't even here yet...".
Northern Gardens is a less deprived working-class area which primarily consists of housing projects, a busy road to the north, and a beach in its northern limits, but still is home to many homeless people that thrive on its resources. It provides Bohan's policing and medical services. The major function of the neighborhood is its housing of the Northern Gardens Projects, one of the largest housing projects in all of Liberty City. While Northern Gardens is still considered to be "the hood", the projects' main complex shows signs of gentrification with the presence of small convenience shops and comparatively modern housing facilities. The police station is directly connected to Northern Gardens Projects by means of a short staircase, presumably to allow for an improved police presence and more effective response to crime.
Boulevard is Bohan's largest and busiest district in terms of traffic. Boulevard primarily consist of a large busy boulevard running through along with various overpasses. Boulevard also contains considerable parkland and a beach in its northern limits. Boulevard is mostly non-residential with the exception of a few low-rise apartments on the boulevard edge. The areas to the south of the district are more urban in character and is focused around the Grand Boulevard thoroughfare. Boulevard has a much lower crime rate compared to the rest of Bohan primarily because it contains few housing areas.
Little Bay is in the far east of Bohan and is the borough's smallest locale. It contains low-rise apartment housing but is very run-down and deprived. Little Bay is also the territory of the Albanian Mob, whom cause much of the crime in the area.
The population of Bohan are mainly of Latin American origin; this population trend is particularly concentrated around Puerto Rican South Bohan and Dominican Fortside. Other ethnic enclaves include the predominant African-American demographic of Northern Gardens and an Albanian presence in Little Bay.
