The Republic of The Earth Sphere Unified Nation is a massive, socially progressive nation, ruled by President Catalonia with a fair hand, and renowned for its daily referendums and irreverence towards religion. The compassionate, hard-working, democratic population of 1.901 billion Terrans hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The medium-sized, outspoken government juggles the competing demands of Education, Healthcare, and Administration. It meets to discuss matters of state in the capital city of Vienna. The average income tax rate is 29.7%.

The strong Terran economy, worth 110 trillion Earthbucks a year, is led by the Tourism industry, with significant contributions from Beef-Based Agriculture, Door-to-door Insurance Sales, and Retail. Average income is 58,253 Earthbucks, and evenly distributed, with the richest citizens earning only 3.4 times as much as the poorest.

Religious education is a new government priority, bad punctuation has come to a full stop, friendly fire incidents usually result in severe burns, and the government has declined to declare any particular religion as its 'official' one. Crime, especially youth-related, is totally unknown. The Earth Sphere Unified Nation's national animal is the Fox, which frolics freely in the nation's many lush forests.

The Earth Sphere Unified Nation is ranked 108,581^st in the world and 2^nd in The Gundam Alliance for Most Developed, scoring 59.68 on the Human Development Index.
