The Constitutional Principality of Yellowfields is a mammoth, socially progressive nation, ruled by Princess Buttercup with an even hand, and notable for its daily referendums, irreverence towards religion, and devotion to social welfare. The compassionate, democratic population of 7.771 billion Yellowfieldsians enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized government is primarily concerned with Welfare, with Education, Administration, and Healthcare also on the agenda, while Spirituality is ignored. It meets to discuss matters of state in the capital city of Amarillo. The average income tax rate is 29.3%, but much higher for the wealthy.

The strong Yellowfieldsian economy, worth 434 trillion buttercups a year, is fairly diversified and led by the Basket Weaving industry, with major contributions from Book Publishing, Soda Sales, and Woodchip Exports. State-owned companies are common. Average income is 55,892 buttercups, and evenly distributed, with the richest citizens earning only 2.9 times as much as the poorest.

Money grows on trees, factories are regularly demolished to make way for low-cost housing areas, the justice of Yellowfields is considered superior to that of other nations, and the government seeks peaceful forum with terrorists. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Yellowfields's national animal is the goldfish, which can occasionally be seen avoiding garbage in the nation's murky oceans.

Yellowfields is ranked 157,169^th in the world and 8^th in Brazen for Highest Average Tax Rates, with 29.32 Effective Tax Rate.
