The Matriarchy of Tiaraville is a colossal, socially progressive nation, notable for its digital currency, sprawling nuclear power plants, and smutty television. The hard-nosed, hard-working, democratic, devout population of 2.763 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, although Administration and Industry are also considered important, 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 250 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 90,823 Diamonds, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 514,049 per year while the poor average 7,862, a ratio of 65.4 to 1.

Snap elections are called over every minor impasse, convicts released after being found "wrongfully imprisoned" are surprisingly chill about the whole thing, the "Underwear of Women in Power" issue of The Ponyville Times is sold out, and a typical fast food menu item could serve a small army. 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 328,084^th in the world and 110^th in Equestria for Safest, scoring 4.17 on the Bubble-Rapp Safety Rating.
