The Dominion of Carroll Mifflin is a colossal, socially progressive nation, renowned for its irreverence towards religion and absence of drug laws. The democratic population of 3.919 billion Carroll Mifflinians 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 large, liberal, socially-minded government juggles the competing demands of Education, Defense, and Law & Order. The average income tax rate is 34.2%, but much higher for the wealthy.

The sizeable but underdeveloped Carroll Mifflinian economy, worth 90.6 trillion aurums a year, is quite specialized and led by the Beef-Based Agriculture industry, with major contributions from Information Technology, Tourism, and Automobile Manufacturing. Black market activity is notable. State-owned companies are common. Average income is 23,123 aurums, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The tenet of free speech is held dear, surveillance cameras are banned, and a large-scale revitalization of the education system is underway. Crime is almost non-existent, thanks to a well-funded police force and progressive social policies in education and welfare. Carroll Mifflin's national animal is the pink fox.

Carroll Mifflin is ranked 150,289^th in the world and 2^nd in Madison for Most Scientifically Advanced, scoring 73.82 on the Kurzweil Singularity Index.
