The Matriarchy of Tiaraville is a colossal, socially progressive nation, notable for its digital currency, free-roaming dinosaurs, and complete absence of social welfare. The hard-nosed, hard-working, democratic, devout population of 2.859 billion ponies live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The minute, liberal, pro-business, outspoken government, or what there is of one, is primarily concerned with Spirituality, with Administration and Industry also on the agenda, while Law & Order and Defense aren't funded at all. It meets to discuss matters of state in the capital city of Ponyville. Citizens pay a flat income tax of 4.1%.

The powerhouse Tiarian economy, worth 261 trillion Diamonds a year, is driven almost entirely by the private sector, which is broadly diversified and dominated by the Retail industry, with significant contributions from Soda Sales, Gambling, and Beef-Based Agriculture. Average income is 91,300 Diamonds, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 518,504 per year while the poor average 7,843, a ratio of 66.1 to 1.

A typical fast food menu item could serve a small army, waste is frequently shipped to other countries, people seem disproportionately distraught when told a museum has a phones-off policy, and academics have a bone to pick with free market entrepreneurs. Crime, especially youth-related, is all-pervasive, probably because of the absence of a police force. Tiaraville's national animal is the Butterfly, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Celestianism.

Tiaraville is ranked 100,488^th in the world and 28^th in Equestria for Largest Cheese Export Sector, scoring 3,250.38 on the Mozzarella Productivity Index.
