The Commonwealth of Marylinn is a large, efficient nation, notable for its frequent executions, compulsory military service, and irreverence towards religion. The hard-nosed, hard-working population of 131 million Maryans have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government juggles the competing demands of Education, Administration, and Defense. The average income tax rate is 35.2%.

The thriving Maryan economy, worth 10.3 trillion Dobloons a year, is broadly diversified and led by the Book Publishing industry, with major contributions from Automobile Manufacturing, Information Technology, and Door-to-door Insurance Sales. Average income is 78,443 Dobloons, and evenly distributed, with the richest citizens earning only 4.9 times as much as the poorest.

Artists are pillars of society, human tissue is grown in vats as a delicacy as well as for transplants, citizens are less concerned with policy and more concerned with whether politicians "call 'em like they see 'em", and Big Agriculture has the government by the nuts. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Marylinn's national animal is the Rat.

Marylinn is ranked 273,852^nd in the world and 26^th in Secret Artist Society for Largest Black Market, with 89.0 billion Standard Monetary Units.
