The Nihilist Hippy Commune of Ummagumma is a gargantuan, environmentally stunning nation, ruled by Prime Minister Roger Waters with a fair hand, and renowned for its state-planned economy, compulsory vegetarianism, and hatred of cheese. The compassionate, democratic, cheerful population of 38.446 billion Ummagummen are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The medium-sized, outspoken government prioritizes Education, although Environment, Industry, and Welfare are also considered important, while Defense and Spirituality receive no funds. It meets to discuss matters of state in the capital city of Bonny. The average income tax rate is 95.2%.

The frighteningly efficient Ummagumman economy, worth a remarkable 9,295 trillion love beads a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is highly specialized, is mostly made up of the Book Publishing industry, with significant contributions from Information Technology and Automobile Manufacturing. Average income is an amazing 241,775 love beads, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Burning twigs to keep warm while lost in the wild is now a felony, RPG fans reminisce fondly about when people thought they were evil and dangerous rather than geeky and socially inept, funerals are often rudely interrupted by juggling clowns shouting for volunteers from the audience, and people seem disproportionately distraught when told a museum has a phones-off policy. Crime, especially youth-related, is so common that it is unusual to encounter someone following the law, probably because of the absence of a police force. Ummagumma's national animal is the far out Pink Dragon, which soars majestically through the nation's famously clear skies, and its national religion is love.

Ummagumma is ranked 206,638^th in the world and 59^th in Wysteria for Most Primitive, scoring -788.2 on the Scary Big Number Scale.
