The National Basketball Association (NBA) is one of the largest professional sports leagues in the world. It consists of 30 teams that are divided into six divisions in order to promote competitive balance within the league. But what exactly are these divisions, and how did they come about? In this article, we’ll go over the history behind the NBA’s six divisions as well as a brief explanation of each one.
Divisions in professional sports have been around for decades, though their purpose has changed drastically over time. Initially, divisions were used to group teams geographically so that travel costs would be reduced and teams could play against nearby rivals more frequently.
As the leagues grew larger and began to span multiple countries, divisions became less focused on location and more focused on creating an even playing field among teams of equal strengths and abilities. This is what we now see in the NBA – six distinct divisions that are designed to create parity in competition between teams and create exciting matchups throughout the season.
History Behind the Divisions
The history of divisions in the NBA can be traced back to 1967 when the league was first divided into two conferences, East and West. These two conferences were then further divided into four divisions: Atlantic, Central, Midwest, and Pacific. This divisional structure remained largely unchanged until 1970 when the Mid-Atlantic Division was added and changed its name to the Southeast NBA Division in 1974.

In 2004, the NBA adopted a new divisional structure consisting of six divisions — Northwest, Pacific, Southwest, Central, Atlantic, and Southeast — that remain in use today. Each division consists of five teams that are grouped together based on their geographical locations or their competitive abilities.
This divisional structure helps create parity among teams by ensuring that they compete against opponents that are at similar levels of talent and ability. It also allows for exciting rivalries between teams within each division as well as inter-division matchups throughout the season.
Divisions also serve a practical purpose as they help determine which teams qualify for playoff contention at the end of each regular season. The top three teams from each division make it to the playoffs while the remaining three spots are filled by the next best teams from across the entire league regardless of their divisional affiliation. This allows for a fair system where teams from all divisions of the NBA have an equal chance of making it to the postseason regardless of their geographic location or strength relative to other teams in their division.
All NBA Divisions – List
NBA Northwest Division
The Northwest Division today is composed of the same 5 teams that it was originally designed for. The Seattle Supersonics were relocated to Oklahoma City in 2008 and renamed the Oklahoma City Thunder.
This division is part of the Western Conference, where teams compete against each other for a chance at a playoff spot. The top three teams from each division make it to the postseason, while the remaining spots are filled by teams with the best records from across the entire league regardless of their divisional affiliation. This system ensures that all divisions in NBA have an equal opportunity to qualify for playoffs each season.
NBA Pacific Division
The Pacific Division of the NBA consists of five teams: the Los Angeles Clippers, Los Angeles Lakers, Golden State Warriors, Sacramento Kings and Phoenix Suns. These teams are part of the Western Conference and have been competing in it since the creation of the NBA in 1940. Initially, the Pacific Division featured the LA Lakers, Portland Trail Blazers, San Diego Rockets, San Francisco Warriors and Seattle SuperSonics.

Over time however, these teams have changed up due to expansion or relocation. Today’s Pacific Division teams provide some of the most exciting matches throughout the season as they strive to become one of the top three teams that qualify for playoffs contention at the end of each regular season.
NBA Southwest Division
In 2004, the league created the Southwest Division to accommodate its expansion to 30 NBA teams. It includes five teams: the Houston Rockets, San Antonio Spurs, Dallas Mavericks, Memphis Grizzlies and New Orleans Pelicans. These teams all compete in the Western Divisions of the NBA. The latest two additions to the division were the Grizzlies and Pelicans who relocated from other cities in order to join it.
The Southwest Division NBA system has been around since the inception of the league in 1940 and has evolved over time to ensure that teams are grouped together based on their geographical locations or their competitive abilities. This helps create parity among teams while also allowing for exciting rivalries between teams within each division as well as inter-division matchups throughout the season.
NBA Central Division
The Central Division of the NBA has been a staple since 1967. It comprises the Detroit Pistons, Milwaukee Bucks, Indiana Pacers, Cleveland Cavaliers and Chicago Bulls. These teams are part of the Eastern Conference, and have all been members of the Central Division NBA since its re-formation in 1970.

Prior to this, it had existed for one season during 1949-50 with 4 teams; The Atlanta Hawks, Baltimore Bullets, Cincinnati Royals and Cleveland Cavaliers. This expansion into 17 teams saw them move over from the Midwest Division as the NBA grew to include two conferences – East and West.
NBA Atlantic Division
The Atlantic Division has been a part of the NBA since 1970, when it was formed with the Philadelphia 76ers, Boston Celtics, New York Knicks, and the now defunct Buffalo Braves. These four teams have continued to compete in the Eastern Conference divisions ever since.
Today, the Atlantic Division is made up of five teams: the 76ers, Toronto Raptors, Celtics, Brooklyn Nets and Knicks. This divisional system has been around since the early days of professional basketball and continues to create exciting rivalries between teams while also ensuring that each team has an equal chance at making it to the playoffs.
NBA Southeast Division
The Southeast Division remains an integral part of the NBA and is home to some of the most exciting teams in the league. It includes the Atlanta Hawks, Orlando Magic, Miami Heat, Charlotte Hornets and Washington Wizards. Each team competes within the Eastern divisions of the NBA and strives to be the best.

The Southeast Division is a highly competitive one with each team having a chance to compete for playoff contention at the end of each season. With such exciting matchups between rivals as well as inter-divisional games throughout the regular season, this division provides fans with plenty of thrilling action.
Winning a Division
When a team wins their Division, they are rewarded with an NBA divisional banner and immortalized in the history books. Although most teams choose not to hang the banner, it serves as a testament to a strong regular season performance and potential playoff berth.
Prior to the 2015-16 season, winning a Division was guaranteed to earn a top 4 seed in the Conference Playoffs, regardless of overall record or standing. This rule has since been abolished; however, its effects were relatively minor.
Did the NBA get rid of Divisions?
Despite the rule changes discussed above, there is still some misunderstanding that Division winners are guaranteed a top four seed and home court advantage. Although this was once true, it is no longer the case. Since the 2015-16 season, Divisions primarily exist for scheduling purposes only, with any added benefits being minimal at best. Nevertheless, winning a Division is still an impressive feat and serves as an indication of strong regular season performance.
Conclusion
In conclusion, the divisions within the NBA have evolved over time to provide a more balanced competitive environment and exciting matchups. While they used to provide teams with a guaranteed top four seed and homecourt advantage, these benefits have since been abolished. Nevertheless, winning a Division is still something that teams strive for as it serves as an indication of strong regular season performance.
