The Inspector Stephan Derrick of Horst Tappert is a gargantuan, cultured nation, ruled by Horst Tappert with an even hand, and remarkable for its sprawling nuclear power plants, punitive income tax rates, and devotion to social welfare. The compassionate population of 34.487 billion Horst Tappertians 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 enormous government prioritizes Education, although Industry, Public Transport, and Environment are also considered important, while Spirituality is ignored. It meets to discuss matters of state in the capital city of Derrickstadt. The average income tax rate is 91.9%.

The frighteningly efficient Horst Tappertian economy, worth a remarkable 4,076 trillion marks a year, is highly specialized and mostly made up of the Book Publishing industry, with significant contributions from Tourism. State-owned companies are common. Average income is an impressive 118,216 marks, and evenly distributed, with the richest citizens earning only 4.1 times as much as the poorest.

A surprising number of police officers have been arrested for derrick sacrifices, Derrickstadt's iconic yellow taxis are nowhere to be seen, citizens are prohibited from raising their voice above thirty decibels in commercial districts, and gigantic marble churches take up almost half the land area of small villages. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Horst Tappert's national animal is the derrick, which frolics freely in the nation's many lush forests, and its national religion is Derrickismus.

Horst Tappert is ranked 20,580^th in the world and 1,181^st in Osiris for Safest, scoring 113.7 on the Bubble-Rapp Safety Rating.
