The United Socialist States of Kozerthia is a very large, socially progressive nation, renowned for its daily referendums, irreverence towards religion, and stringent health and safety legislation. The compassionate, democratic population of 217 million Kozerthians 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 Education, Welfare, and Administration. The average income tax rate is 30.7%, but much higher for the wealthy.

The sizeable but inefficient Kozerthian economy, worth 9.12 trillion condoms a year, is led by the Book Publishing industry, with major contributions from Pizza Delivery, Beef-Based Agriculture, and Information Technology. State-owned companies are common. Average income is 42,045 condoms, and distributed extremely evenly, with little difference between the richest and poorest citizens.

A suspicious number of male students have joined the Ladies' Wrestling League, metal detectors have been banned after a bottle cap caused a riot at the beach, the television adaptation of Jennifer Government is the most popular program in the nation, and drug lords often avoid prison time by teaching "chemistry" classes to underprivileged youth. Crime, especially youth-related, is totally unknown. Kozerthia's national animal is the NYN姉貴, which frolics freely in the nation's many lush forests.

Kozerthia is ranked 109,172^nd in the world and 33^rd in Eientei Gensokyo for Most Eco-Friendly Governments, scoring 790.06 on the Dolphin Recycling Awareness Index.
