Map of the legislative organizations of the countries of the world, originally by Aris Katsaris.  Note: This only shows national legislatures, federations with sublegislatures are not required to have sublegislatures on the same model as their country: The United States has a bicameral legislature, the State of Nebraska has a unicameral legislature.  Similarly, although Canada has a bicameral legislature, all of its provinces and territories have unicameral legislatures. Note: Any official "legislature", including unelected and powerlessly limited ones, are counted. Countries without a functioning legislature, such as countries governed by a military junta, are coloured black.
