The Republic of Sinkuun is a huge, socially progressive nation, notable for its compulsory military service. The hard-working, democratic population of 209 million Sinkuunians hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The relatively small government juggles the competing demands of Education, Defense, and Welfare. The average income tax rate is 17.6%.

The Sinkuunian economy, worth 11.6 trillion Cats a year, is broadly diversified and led by the Cheese Exports industry, with major contributions from Book Publishing, Furniture Restoration, and Trout Farming. Average income is 55,683 Cats, and evenly distributed, with the richest citizens earning only 3.7 times as much as the poorest.

Children as young as eight can present logical proofs for the existence of the afterlife, criminals lock themselves in their mums' basements to avoid prison, Sinkuunians refer to transgender people with insults instead of pronouns, and advertisements read like science journal articles complete with extensive references. Crime, especially youth-related, is totally unknown. Sinkuun's national animal is the Lion, which frolics freely in the nation's many lush forests.

Sinkuun is ranked 88,747^th in the world and 522^nd in Europe for Highest Disposable Incomes, with 45,883.21 Standard Monetary Units.
