The Computerized Kingdom of Impel Down is a massive, cultured nation, ruled by Overseer Apollo with an iron fist, and renowned for its museums and concert halls, frequent executions, and punitive income tax rates. The hard-nosed, hard-working, cynical population of 2.939 billion Impelians are proud of their wide-ranging civil freedoms, and those who aren't tend to be dragged off the streets by men in dark suits and hustled into cars with tinted windows.

The medium-sized, corrupt government juggles the competing demands of Education, Defense, and Industry. It meets to discuss matters of state in the capital city of Los Phantom A-1. The average income tax rate is 75.8%.

The frighteningly efficient Impelian economy, worth 494 trillion gils a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Tourism, Arms Manufacturing, and Retail. Average income is an impressive 168,197 gils, and evenly distributed, with the richest citizens earning only 3.5 times as much as the poorest.

Impel Down's free colleges struggle to maintain standards in the face of overwhelming demand, unemployed accountants keep double-entry ledgers of their benefit claims, the "Dreadnowt" is the pride and joy of the Impelian Navy, and a ban on robots in disguise has transformed the entertainment industry. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Impel Down's national animal is the dragon, which is also the nation's favorite main course, and its national religion is Mechanical Network Erudition Acts.

Impel Down is ranked 246,184^th in the world and 10,759^th in The North Pacific for Most Rebellious Youth, scoring -17 on the Stark-Dean Displacement Index.
