The D of D of Derilla is a colossal, efficient nation, ruled by D with an even hand, and notable for its disturbing lack of elderly people, enslaved workforce, and punitive income tax rates. The hard-nosed, humorless, devout population of 5.949 billion Derillans are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The medium-sized, corrupt, socially-minded government juggles the competing demands of Industry, Law & Order, and Education. It meets to discuss matters of state in the capital city of D. The average income tax rate is 81.6%, and even higher for the wealthy.

The frighteningly efficient Derillan economy, worth a remarkable 1,567 trillion Nerds a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, fairly diversified black market in Arms Manufacturing, Information Technology, Woodchip Exports, and Uranium Mining. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 263,425 Nerds, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Citizens live in superstitious fear of the mysterious glowing clouds that float over Derilla, politicians bribe ten-year-old geniuses to sit their aptitude tests, trying to toast marshmallows in an electric fireplace just isn't the same, and retiring citizens are dragged away in the middle of the night by mysterious men in black suits. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Derilla's national animal is the Unicorn, which teeters on the brink of extinction due to widespread deforestation.

Derilla is ranked 89,501^st in the world and 72^nd in Nerdlandia for Largest Populations, with 5.95 billion capita.
