The Commonwealth of Decrosca is a huge, safe nation, remarkable for its compulsory military service, frequent executions, and complete absence of social welfare. The hard-nosed, hard-working, cynical, humorless population of 336 million Decroscans 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, corrupt, moralistic, well-organized government juggles the competing demands of Law & Order, Industry, and Defense. It meets to discuss matters of state in the capital city of Sim City. The average income tax rate is 32.8%.

The frighteningly efficient Decroscan economy, worth 31.4 trillion Simoleons 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 large, well-organized, broadly diversified black market in Uranium Mining, Information Technology, Door-to-door Insurance Sales, and Furniture Restoration. 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 93,367 Simoleons, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

Conspiracy theorists allege that the government is spying on them through their carbon monoxide detectors, the nanny industry has had a boom after maternity leave was recently banned, teachers regularly paddle unruly students, and Big Brother is still watching even when your big brother is dead. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force. Decrosca's national animal is the Cockroach, which teeters on the brink of extinction due to widespread deforestation.

Decrosca is ranked 143,289^th in the world and 2,450^th in The East Pacific for Largest Cheese Export Sector, scoring 1,365.47 on the Mozzarella Productivity Index.
