The Nihilist Hippy Commune of Ummagumma is a gargantuan, genial nation, ruled by Prime Minister Roger Waters with a fair hand, and renowned for its daily referendums, avant-garde cinema, and restrictive gun laws. The compassionate, democratic, cheerful population of 31.775 billion Ummagummen love a good election, and the government gives them plenty of them. Universities tend to be full of students debating the merits of various civil and political rights, while businesses are tightly regulated and the wealthy viewed with suspicion.

The medium-sized, socially-minded government prioritizes Education, although Environment, Welfare, and Industry 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 94.0%, and even higher for the wealthy.

The frighteningly efficient Ummagumman economy, worth a remarkable 7,654 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 240,905 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 2,061^st in the world and 30^th in Wysteria for Most Efficient Economies, scoring 100 on the Krugman-Greenspan Business Outlook Index.
