The Empire of Mayor-upon-bridge is a massive, safe nation, ruled by Prime Minister with an even hand, and renowned for its smutty television, daily referendums, and punitive income tax rates. The hard-nosed, hard-working, devout population of 2.352 billion Mayor-upon-bridgeans 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 medium-sized government juggles the competing demands of Law & Order, Administration, and Industry. It meets to discuss matters of state in the capital city of St Francis. Citizens pay a flat income tax of 59.9%.

The frighteningly efficient Mayor-upon-bridgean economy, worth 418 trillion Pounds a year, is broadly diversified and led by the Retail industry, with major contributions from Information Technology, Arms Manufacturing, and Uranium Mining. Average income is an impressive 178,002 Pounds, with the richest citizens earning 5.4 times as much as the poorest.

Young children are regularly seen wagering pocket money at blackjack tables, the government is continually probing the galaxy in search of alien life, the police crack down on tax evaders without mercy, and owning a tractor is widely regarded as an essential prerequisite to most government positions. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mayor-upon-bridge's national animal is the Red Deer, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Catholicism.

Mayor-upon-bridge is ranked 135,968^th in the world and 25^th in The Great Monarchical Nations for Most Eco-Friendly Governments, scoring 484.56 on the Dolphin Recycling Awareness Index.
