The National Atlas offers simple maps of each District of the 112th Congress (January 2011-January 2013). These maps of the individual districts cover half of an 8.5- by 11-inch paper when printed. Designed for easy reference, they show the Congressional District overlaid on top of State and county boundaries along with interstate and US highways, selected streams and waterbodies, and major cities. The maps were created for use on the World Wide Web but print well using your home or office printer.
