The United Kingdom of Mattielandia is a colossal, environmentally stunning nation, ruled by Mattie the Dog with an even hand, and renowned for its museums and concert halls, free-roaming dinosaurs, and anti-smoking policies. The compassionate, cheerful population of 7.686 billion Mattielandians enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The enormous, liberal, socially-minded government juggles the competing demands of Education, Administration, and Healthcare. It meets to discuss matters of state in the capital city of Grey City. The average income tax rate is 96.9%.

The frighteningly efficient Mattielandian economy, worth a remarkable 1,236 trillion Doodles 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 Information Technology industry, with significant contributions from Book Publishing and Tourism. Average income is an impressive 160,886 Doodles, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

A weakened police force struggles to maintain law and order, a sudden shout of "surprise!" does not herald a party for teachers, the nation has welcomed its expats back with open arms, and the government awards prizes to television shows featuring stereotype-breaking minority roles. Crime, especially youth-related, is totally unknown. Mattielandia's national animal is the Greyhound, which frolics freely in the nation's many lush forests.

Mattielandia is ranked 286,260^th in the world and 240^th in Karma for Most Primitive, scoring -480.42 on the Scary Big Number Scale.
