The Holy Blue Republic of MacSween is a mammoth, safe nation, ruled by MacSween with an even hand, and renowned for its daily referendums, triple-decker prams, and prohibition of alcohol. The hard-nosed, devout population of 8.556 billion MacSweenians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized government juggles the competing demands of Law & Order, Healthcare, and Defense. It meets to discuss matters of state in the capital city of Sweeny City. Citizens pay a flat income tax of 28.6%.

The large but inefficient MacSweenian economy, worth 387 trillion Gold Coins a year, is led by the Arms Manufacturing industry, with significant contributions from Trout Farming, Door-to-door Insurance Sales, and Beef-Based Agriculture. State-owned companies are common. Average income is 45,314 Gold Coins, with the richest citizens earning 7.4 times as much as the poorest.

Foreign nations kill migratory animals at random in the hope that MacSween will pay them to stop, a referendum must be held in order for any new law to be passed, every diamond ring sold is accompanied by a twenty-five page analysis and a waiver, and passive-aggressive congratulations cards inform mums-to-be that their pregnancy is their greatest achievement in life. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. MacSween's national animal is the Zombie, which is also the nation's favorite main course, and its national religion is McSweenism.

MacSween is ranked 254,942^nd in the world and 7^th in Galactic Empire of Sween for Most Cultured, scoring 62 on the Snufflebottom-Wiggendum Pentatonic Scale.
