District 1's industry is manufacturing luxury items for the Capitol. Due to the nature of its industry, District 1 considered the wealthiest district, the only other wealthier place being the Capitol itself
District 2's industry is masonry, but also manufactures weaponry, makes trains, and supplies the nation's Peacekeepers. The main military complex in the district is known as the Nut. Citizens of District 2 are sometimes called "the pets" of the Capitol. They are the biggest supporters of the Capitol and therefore are pampered and given many extra conveniences.
District 3's primary industry is general electronics of many types, though it is known for also making various mechanical products such as automobiles and firearms. Their tributes are skilled with electronics and engineering. Some notable tributes are Wiress and Beetee.
District 4's industry is fishing, thus most residents have experience using nets and tridents, making fishhooks from scratch, swimming, and identifying edible sea life. It is considered a Career district, alongside District 1 and 2, and notable victors from this district are Finnick Odair, Mags, and Annie Cresta. Finnick was an important ally of Katniss Everdeen in the Quarter Quell
District 5's industry is power production, which is emphasized by the presence of a large hydroelectric dam in the district. Foxface, a clever tribute nicknamed by Katniss in the 74th Hunger Games, was from District 5. In the 75th Hunger Games the man from District 5 was the first person to die, while he attacked Katniss.
District 6's industry is transportation. In the 75th Hunger Games, two of the past winners ended up becoming morphling addicts. Another known tribute from District 6 was Titus.
District 7's industry is lumber and many of its residents have experience with hatchets, axes, saws, and other tree cutting tools. Katniss notes that District 7 children begin work at an early age. Katniss and Peeta furthermore note they had to travel through District 7 to get to the Capitol. Johanna Mason and Blight came from this District.
District 8's industry is the production of textiles, and they have at least one factory that is primarily used for making Peacekeeper uniforms. It was the first district to rebel after Katniss Everdeen spurred the revolution after the 74th Hunger Games. The rebellion worsened conditions for residents and some, including Bonnie and Twill, escaped. However, Bonnie and Twill never made it to safety in District 13. Cecelia and Woof were victors from District 8.
District 9's industry is grain. Little is known about this district, just that there are large numbers of farmland for the production of grain. In the 74th Hunger Games, the boy from District 9 was the first person to be killed in the book.
District 10's industry is livestock. Not much is known about this district, but some known information is that its marriage rituals are similar to that of District 4's. In the 74th Hunger Games, Katniss names the boy from District 10 "the boy with the bad leg" as he was crippled.
District 11's industry is agriculture - orchards of various fruits, fields of grain, and cotton surround the district. Almost everything grown is shipped directly to the Capitol, leaving little for its district residents. As such, it is one of the poorest districts in Panem, second only to District 12. In addition, it is also one of the districts where the Peacekeepers are the strictest, with a fortified wall surrounding the district. Ironically, this directly results in its residents generally being malnourished and underfed despite its focus on agriculture. Rue and Thresh were notable tributes.
District 12's industry is coal and is located somewhere near what was the Appalachian mountains. The district has the distinction of being one of the poorest districts, if not the outright poorest, in all of Panem. Before Katniss Everdeen and Peeta Mellark won the 74th Hunger Games, the district had not had a winner of the Hunger Games emerge from the ranks of its residents for twenty-four years since Haymitch Abernathy, a raging alcoholic and an embarrassment to the district, won the 50th Hunger Games. Before Haymitch, there was only one other victor (Lucy Gray Baird) from District 12, forty years before Haymitch's victory in the 50th Hunger Games and the last female victor before Katniss's joint victory with Peeta in the 74th Hunger Games, 64 years later.
District 13 was one of the thirteen districts of Panem. Its main industry was nuclear research and technology, including the production of nuclear weapons. In addition it served as the Capitol's original command and control center for its military-industrial complex. District 13 was the instigator of the First Rebellion and led the other twelve districts in revolution against the oppression of the Capital. At the climax of the First Rebellion, the district was supposedly obliterated as a warning to the other twelve districts of the Capitol's might and that further resistance was futile. In the years following the Dark Days, the Capitol led Panem's population to widely believe that the main industry of District 13 was graphite mining and that the district was now an uninhabitable ruin, supposedly still smoldering from the toxic bombs dropped upon it.
