The Half-Blood Prince of Prof Snape is a gargantuan, orderly nation, ruled by Voldemort with an iron fist, and remarkable for its strictly enforced bedtime, punitive income tax rates, and complete absence of social welfare. The hard-nosed, hard-working, cynical, humorless population of 12.28 billion Slytherins are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government juggles the competing demands of Law & Order, Education, and Industry. It meets to discuss matters of state in the capital city of Azkaban. The average income tax rate is 59.5%.

The frighteningly efficient Slytherin economy, worth a remarkable 1,770 trillion Knuts a year, is fairly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Uranium Mining, and Automobile Manufacturing. Black market activity is rampant. Average income is an impressive 144,197 Knuts, and evenly distributed, with the richest citizens earning only 3.9 times as much as the poorest.

It turns out that money can buy you happiness, troublemakers boast about how many times they have to visit their therapist, news headlines usually include p-values, and the studies of art and philosophy are banned. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Prof Snape's national animal is the Basilisk, which is also the nation's favorite main course, and its national religion is Death Eaters.

Prof Snape is ranked 2,683^rd in the world and 1^st in Hogwarts for Fattest Citizens, with 35.62 Obesity Rate.
