* District 1: Luxury goods (jewelry, precious metals, gemstones)
* District 2: Masonry, weaponry, Peacekeeper training
* District 4: Fishing
These three districts were the most loyal to the Capitol and known for their ruthless training programs and highly skilled tributes in the Games. While District 4 was primarily focused on fishing, they also had a history of producing strong tributes, as seen with Rue in *The Hunger Games*.
It's important to note that District 11 also had some connection to the career districts, as they primarily worked in agriculture and were known for their close relationship with District 2.
While not officially considered a "career" district, District 3 also had a strong presence in the Games due to their technology-based industry. They often produced tributes with strategic and tactical skills.
