District 3

District 3's main industry is electronics. They specialize in televisions, automobiles, and explosives. Before the rebellion it was one of the richest districts in Panem, but it is implied in Catching Fire that their citizens lived in abject poverty, as they were one of the first districts to start an uprising. Most of its inhabitants work in factories and are very well adept with engineering. The bread from this district is bite-sized square-shaped rolls.

Tributes

 * Wiress - the 75th Hunger Games (a Quarter Quell) and a previous Games.
 * Beetee - the 75th Hunger Games, along with a previous Games.
 * Unnamed District 3 boy - 74th Hunger Games
 * Unnamed District 3 girl - 74th Hunger Games

Wiress and Beetee were part of the alliance of the rebellion in the 75th Hunger Games, though Wiress did not survive it. Wiress was the first to figure out that the arena is shaped a clock, which was important for the survival of the others. Beetee planned to destroy the arena so that District 13 could rescue the tributes, but he was knocked out before he could carry this out and Katniss did it instead.

Although he was never named, the male tribute from District 3 in the 74th Hunger Games proved himself to be useful to the Careers due to his experience with explosives. He dug up the land mines that surrounded the plates near the Cornucopia that had been deactivated once the Games began. Then, using the skills he had acquired from living in District 3, he reactivated them and buried them around the pile of supplies and food that the Careers relied on. This was a booby trap to kill anyone who attempted to steal their food. However, Foxface managed to discover the route that could lead her to their supplies without triggering the land mines, which allowed her to steal from them when they weren't watching. Later, Katniss decided to level the playing field by destroying their supplies. She used her arrows to shoot at a bag of apples, causing them to spill out and trigger the land mines. The explosions destroyed nearly everything, including one of Katniss' eardrums. Once the Careers returned, Cato was furious and blamed the boy from District 3 for doing his job too well. He quickly killed the boy by snapping his neck.

The female tribute from the 74th Hunger Games died on the first day, most likely in the bloodbath at the Cornucopia.
