Where does Katniss live within District 12?

Katniss and her family live in the section of District 12 known as the Seam.  
In chapter one, Katniss gives readers background information about herself, her family, District 12, and their house.  She informs readers that District 12 is a mining district, and the Seam is where many of the miners live.  Katniss further clarifies her house's location by telling readers that it is on the outer edges of the Seam.  She says that she only has to go through a few gates to reach a run down field called the Meadow.  

Our house is almost at the edge of the Seam. I only have to pass a few gates to reach the scruffy field called the Meadow. Separating the Meadow from the woods, in fact enclosing all of District 12, is a high chain-link fence topped with barbed wire loops.

The Meadow is important because it borders the forest.  Between the two is a chain link fence that is meant to keep predators out and the people of District 12 in.  Katniss ignores this rule because she goes outside of the fence in order to hunt for food for her family.

Most of the Peacekeepers turn a blind eye to the few of us who hunt because they’re as hungry for fresh meat as anybody is.
