The Commonwealth of Mateussino is a huge, orderly nation, renowned for its frequent executions, keen interest in outer space, and parental licensing program. The compassionate, cynical, devout population of 620 million Mateussinors 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 Administration, Law & Order, and Healthcare. It meets to discuss matters of state in the capital city of Mateusinsk. The average income tax rate is 37.3%, but much higher for the wealthy.

The all-consuming Mateussinor economy, worth 67.2 trillion Matreals a year, is broadly diversified and dominated by the Tourism industry, with significant contributions from Basket Weaving, Book Publishing, and Cheese Exports. State-owned companies are common. Average income is an impressive 108,343 Matreals, and evenly distributed, with the richest citizens earning only 2.3 times as much as the poorest.

The Mateussino Automotive Racing Series draws millions of spectators annually while those near the tracks complain about the noise, mantis shrimp studies is academia's fastest-growing field, the government baselessly accuses foreign dignitaries of being assassins, and foreigners with shady pasts are fleeing the country. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Mateussino's national animal is the Wither And Mateussino Cat, which frolics freely in the nation's many lush forests.

Mateussino is ranked 86,664^th in the world and 1,004^th in The East Pacific for Most Eco-Friendly Governments, scoring 1,112.2 on the Dolphin Recycling Awareness Index.
