The Dominion of Brook is a mammoth, efficient nation, ruled by Brook with an even hand, and notable for its museums and concert halls, daily referendums, and sprawling nuclear power plants. The compassionate, democratic, devout population of 7.776 billion Straw Hats are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The enormous government juggles the competing demands of Administration, Education, and Welfare. It meets to discuss matters of state in the capital city of West Blue. The average income tax rate is 84.2%, and even higher for the wealthy.

The thriving Straw Hatian economy, worth 668 trillion souls a year, is quite specialized and led by the Trout Farming industry, with significant contributions from Information Technology, Arms Manufacturing, and Basket Weaving. Black market activity is notable. State-owned companies are common. Average income is 85,964 souls, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Midnight pizza breaks are common among the work-from-home population, fire stations and hospitals can't deploy emergency vehicles because badly parked cars block them in, fancy dress parties are raided by military police for new recruits, and the new Giraffe Supremacy Party is faring well in the polls. Crime is totally unknown, despite the fact that it is difficult to make it through a day without breaking one of the country's many laws. Brook's national animal is the giraffe, which frolics freely in the nation's many lush forests, and its national religion is Cho.

Brook is ranked 173,892^nd in the world and 4^th in Straw Hats for Largest Manufacturing Sector, scoring 7,074.87 on the Gooback-Jerbs Productivity Index.
