The United States of 5105 is a colossal, socially progressive nation, renowned for its state-planned economy, restrictive gun laws, and devotion to social welfare. The compassionate, democratic population of 5.466 billion 5105ians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized, socially-minded government juggles the competing demands of Welfare, Education, and Healthcare. It meets to discuss matters of state in the capital city of New Olympus. The average income tax rate is 45.7%, but much higher for the wealthy.

The sizeable but stagnant 5105ian economy, worth 76.1 trillion florins a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is broadly diversified, is led by the Automobile Manufacturing industry, with major contributions from Information Technology, Retail, and Door-to-door Insurance Sales. Average income is 13,926 florins, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

The "Underwear of Women in Power" issue of The New Olympus Times is sold out, every spring railroad foundations erode to reveal human remains, prisoners can't do number twos without their "toilet buddy" present, and the family summer vacation has become a thing of the past following the introduction of the year-round school year. Crime is totally unknown. 5105's national animal is the beaver, which frolics freely in the nation's many lush forests.

5105 is ranked 16,751^st in the world and 1^st in 314159265358979323846264338327950 for Safest, scoring 115.65 on the Bubble-Rapp Safety Rating.
