The Grand Empire of the Species of Mangoville is a colossal, efficient nation, ruled by Emperor-King Ducky with an iron fist, and notable for its free-roaming dinosaurs, frequent executions, and stringent health and safety legislation. The compassionate, cynical, humorless population of 6.448 billion Mangovilleans are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government juggles the competing demands of Education, Healthcare, and Administration. It meets to discuss matters of state in the capital city of Mangoville city or Sesaurius. The average income tax rate is 62.3%, and even higher for the wealthy.

The frighteningly efficient Mangovillian economy, worth a remarkable 1,391 trillion Mangoes 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 an enormous, deeply entrenched black market in Information Technology, Tourism, Arms Manufacturing, and Book Publishing. 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 an amazing 215,837 Mangoes, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Children spend all morning taking out a comma and all afternoon putting it back in again, the most common psychiatric diagnosis is to 'stop whining and grow up', excessive wheelchair ramps on government buildings have been compared to theme park attractions, and in life full of care there is no time to stop and stare. Crime is totally unknown. Mangoville's national animal is the T rex, which is also the nation's favorite main course, and its national religion is Mango-Catholism.

Mangoville is ranked 34,392^nd in the world and 113^th in Conch Kingdom for Lowest Crime Rates, with 80.27 law-abiding acts per hour.
