The Republic of The Mars Union is a colossal, safe nation, ruled by Chairwoman Bernstein with a fair hand, and remarkable for its smutty television, daily referendums, and stringent health and safety legislation. The compassionate, democratic population of 2.528 billion Martians are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The medium-sized, liberal government juggles the competing demands of Healthcare, Education, and Administration. It meets to discuss matters of state in the capital city of Chryse. The average income tax rate is 44.4%, but much higher for the wealthy.

The Martian economy, worth 120 trillion Marscoins a year, is led by the Tourism industry, with major contributions from Retail, Information Technology, and Soda Sales. State-owned companies are common. Average income is 47,585 Marscoins, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Hordes of unemployed lumberjacks have resorted to cutting down utility poles to satisfy their cravings, the term cold case has taken on a very literal meaning, the government has declined to declare any particular religion as its 'official' one, and guide dogs for the blind have been seen using government websites. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. The Mars Union's national animal is the Chryse Hawk, which soars majestically through the nation's famously clear skies.

The Mars Union is ranked 109,893^rd in the world and 2^nd in The Gundam Alliance for Most Rebellious Youth, scoring zero on the Stark-Dean Displacement Index.
