The Deep Black Canyon of Rocke Bottom is a gargantuan, genial nation, ruled by Underbelly with an even hand, and renowned for its museums and concert halls, rampant corporate plagiarism, and digital currency. The compassionate, democratic population of 26.923 billion Rocke Bottomers 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 large government juggles the competing demands of Industry, Education, and Social Policy. It meets to discuss matters of state in the capital city of Downunder City. The average income tax rate is 52.9%.

The frighteningly efficient Rocke Bottomian economy, worth a remarkable 1,915 trillion rockes 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 a large, well-organized, quite specialized black market in Tourism, Information Technology, Basket Weaving, and Cheese Exports. 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 71,147 rockes, and evenly distributed, with the richest citizens earning only 3.6 times as much as the poorest.

Ratings for sitcom reruns are often much higher than election debates, "Underbelly got your tongue?" has become a popular idiom, bowling teams spend more time looking at their phones than the pins, and schoolchildren have more trading cards than flash cards in their backpacks. Crime, especially youth-related, is a serious problem, perhaps because of the country's complete lack of prisons. Rocke Bottom's national animal is the Rocke lobster, which frolics freely in the nation's sparkling oceans.

Rocke Bottom is ranked 208,349^th in the world and 8^th in God Only Knows Why This Region Exists for Least Corrupt Governments, with 92.49 percentage of bribes refused.
