The Republic of Interceptor IV is a titanic, environmentally stunning nation, remarkable for its burgeoning dolphin population. The quiet, industrious population of 13.737 billion Interceptor IVians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government juggles the competing demands of Law & Order, Defense, and Education. The average income tax rate is 24.4%, but much higher for the wealthy.

The Interceptor IVian economy, worth 531 trillion dollars a year, is led by the Beef-Based Agriculture industry, with major contributions from Gambling, Cheese Exports, and Basket Weaving. State-owned companies are reasonably common. Average income is 38,667 dollars, and evenly distributed, with the richest citizens earning only 2.9 times as much as the poorest.

Crime is well under control, thanks to a capable police force and progressive social policies in education and welfare. Interceptor IV's national animal is the dolphin, which frolics freely in the nation's sparkling oceans.

Interceptor IV is ranked 125,742^nd in the world and 6,214^th in Lazarus for Most Eco-Friendly Governments, scoring 601.72 on the Dolphin Recycling Awareness Index.
