The Language-Learning Cult of Duolingonia is a massive, orderly nation, remarkable for its avowedly heterosexual populace, enslaved workforce, and complete absence of social welfare. The hard-nosed, hard-working, cynical, humorless population of 4.533 billion Duolingonians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The relatively small, corrupt, moralistic, well-organized government juggles the competing demands of Defense, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Pittsburgh. Citizens pay a flat income tax of 22.7%.

The frighteningly efficient Duolingonian economy, worth 788 trillion lingots a year, is broadly diversified and led by the Retail industry, with major contributions from Arms Manufacturing, Uranium Mining, and Information Technology. Black market activity is rampant. Average income is an impressive 174,025 lingots, with the richest citizens earning 5.4 times as much as the poorest.

Leader is described as an everyday person with normal tastes and the usual interests, the nation frequently scolds its subject territories for staying up past bedtime, a popular Duolingonian saying is 'wishing upon a fallen jet engine', and shorter foreigners are often forcibly deported on suspicion of working for the World Assembly. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Duolingonia's national animal is the green owl, which is also the nation's favorite main course.

Duolingonia is ranked 24,946^th in the world and 21^st in Artificial Solar System for Most Scientifically Advanced, scoring 246.89 on the Kurzweil Singularity Index.
