The Theocratic Matriarchy of Marsh Kate is a titanic, cultured nation, ruled by Kate Marsh with a fair hand, and remarkable for its museums and concert halls, multi-spousal wedding ceremonies, and punitive income tax rates. The compassionate, hard-working, democratic, cheerful, devout population of 15.091 billion Marsh Kateans hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The medium-sized, liberal, outspoken government juggles the competing demands of Administration, Industry, and Education. It meets to discuss matters of state in the capital city of Arcadia Bay. The average income tax rate is 62.3%, and even higher for the wealthy.

The frighteningly efficient Marsh Katean economy, worth a remarkable 2,018 trillion dollars a year, is fairly diversified and dominated by the Tourism industry, with significant contributions from Book Publishing, Information Technology, and Retail. Average income is an impressive 133,727 dollars, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Glittering new sports stadiums adorn every city and town, war criminals are given full state funerals, no one is quite sure what many government officials look like, and nobody is allowed to stop the local daycare from reading Nietzsche to pre-schoolers. Crime is totally unknown. Marsh Kate's national animal is the rabbit, which frolics freely in the nation's many lush forests, and its national religion is Christianity.

Marsh Kate is ranked 26,056^th in the world and 26^th in Wintreath for Largest Trout Fishing Sector, scoring 5,929.48 on the Nemo Depletion Efficiency Index.
