The Grand Industry Migration

This [Ratmas 2010 event] changed the district industries to more closely align with the industries revealed in Mockingjay. The district board descriptions were updated, and characters were permitted to move districts or change jobs to match the new industries, if their writers desired.

Former district industry descriptions

District	Description
District One	Nearly all of the Capitol's luxury items are made in District One. The people of this district are rarely hungry, and they train their children to compete in the Hunger Games.
District Two	District Two speacializes in medicine; their doctors are some of the best in the country. Their techniques are passed on to the Capitol's own doctors.
District Three	Factories, manufacturing, technology; that's all District Three. This district is large and dotted with the high-tech factories; the only issue is that pollution can sometimes be rather bad.
District Four	The citizens of District Four are all serious fishers; give them a fishing pole and they'll come back with a truckload of fish. Most of this food is shipped to the Capitol; but they have more than enough left for themselves.
District Five	Animals are found abundantly in District Five; the residents specialize in breeding and selling them. They are born with a deep understanding of wildlife.
District Six	District Six are the scientists of the country; discovering new remedies, uncovering explanations for the country's problems; it's all them.
District Seven	If you happened to come across District Seven, you would come across construction to the highest extent. These citizens are good with a hammer and nails.
District Eight	Cotton is grown in District Eight, and sheep are raised. Why? Because these people are weavers, and specialize in producing clothing for the Capitol.
District Nine	District Nine are hunters, but they are only permitted to hunt strictly within their district limits. Anywhere else is prohibited.
District Ten	District Ten citizens love mathematics, and is the only district besides the Capitol that interact with foreign countries, through trade and negotiation. Their district lies on what was once called the Missisippi River, and boats carrying goods traverse it.
District Eleven	District Eleven is entirely agricultural, dotted with orchards, fields, and the like. Most of the food grown is given to the Capitol.
District Twelve	The last and final district, Twelve, are coal miners. Their district is normally the hungriest, but they get by. The coal they mine is mostly given to the Capitol as directed.
