The Republic of Roy Mustang is a massive, environmentally stunning nation, remarkable for its infamous sell-swords, ubiquitous missile silos, and frequent executions. The hard-nosed, cynical, devout population of 3.712 billion Roy Mustangians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, moralistic government juggles the competing demands of Law & Order, Defense, and Healthcare. The average income tax rate is 24.9%.

The strong Roy Mustangian economy, worth 237 trillion cenzes a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a slick, highly efficient, fairly diversified black market in Information Technology, Trout Farming, Beef-Based Agriculture, and Woodchip Exports. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is 63,912 cenzes, and evenly distributed, with the richest citizens earning only 3.8 times as much as the poorest.

There's a lot of hot air coming from the Capitol Building, depression sinks in after each election when voters realize they are stuck with these people for years, children are regularly married to each other to secure alliances between families, and state officials tend to disappear after they forget to salute Leader's portrait. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Roy Mustang's national animal is the alchemist, which is also the nation's favorite main course.

Roy Mustang is ranked 26,529^th in the world and 75^th in Remembrance for Safest, scoring 110.81 on the Bubble-Rapp Safety Rating.
