Detroit is an independent city located in Wayne County, Michigan, covering a vast area of approximately 138.8 square miles (about 360 km²). For administrative convenience, the entire city is divided into 7 council districts, with one council member elected from each district.

However, everyday addresses or neighborhood names are often referred to by traditional neighborhood units rather than these electoral districts. The city of Detroit officially recognizes over 200 neighborhoods, which can feel somewhat complex for newcomers settling in the city.

The major areas can be broadly divided into Downtown, Midtown, Corktown, New Center, East Side, and West Side. Downtown is the core of the city, densely populated with the Renaissance Center, GM headquarters, major commercial facilities, and sports venues (Little Caesars Arena, Comerica Park, Stadium District). Midtown is centered around Wayne State University and is home to cultural institutions like the Detroit Institute of Arts (DIA), the Detroit Historical Museum, and the Motown Museum.

Corktown is the oldest residential area in Detroit, where Irish immigrants first settled in the 19th century, and it now features trendy restaurants, bars, and the Ford Michigan Central Station redevelopment area.

To the east, there are historic upscale residential districts like Indian Village and Park Fair, while to the northeast, the traditional market district around Eastern Market exists. The West Side features the historic Boston-Edison district, known for its well-preserved large homes built in the 1910s to 1930s.

Rivertown is an area along the Detroit River that is currently undergoing active residential and commercial development. West Village is a charming neighborhood filled with small independent shops and cafes, popular among younger crowds.

When understanding Detroit's administrative districts, it is important to distinguish them from the surrounding metropolitan area just outside the city limits. While the city of Detroit itself is quite large, many immigrant communities, including Koreans, reside in suburban areas outside the city boundaries.

To the north, major suburban cities include Troy, Novi, West Bloomfield, Southfield, and Auburn Hills in Oakland County; to the east, Sterling Heights and Warren in Macomb County; and to the west, Dearborn and River Rouge in Wayne County.

The entire Metro Detroit area is referred to as the Greater Detroit area, with a population of about 4.4 million. Considering the actual living radius, it is more practical to understand the region in terms of this metropolitan concept rather than just the city limits.

ZIP Codes in Detroit range from 48201 to 48239, with different ZIPs assigned to each neighborhood. For example, Midtown primarily uses 48201, Downtown uses 48226, and Corktown and the East Side have other numbers.

It is essential to verify the correct ZIP when receiving mail or using delivery services. For those settling in Detroit for the first time or needing information about specific areas, the Michigan community development website or the neighborhood information section of the official Detroit portal (detroitmi.gov) can be helpful resources.
