The Natural Union of Fringillidae is a colossal, orderly nation, ruled by Carduelinae with an iron fist, and remarkable for its enslaved workforce, hatred of cheese, and punitive income tax rates. The hard-nosed, cynical, humorless, devout population of 6.629 billion Fringillidaeans are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The enormous, corrupt, moralistic, well-organized government is primarily concerned with Defense, although Law & Order, Spirituality, and Administration are also considered important, while Welfare and Education are ignored. It meets to discuss matters of state in the capital city of Pyrrhula. Citizens pay a flat income tax of 86.4%.

The strong Fringillidaean economy, worth a remarkable 1,073 trillion finches a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, quite specialized black market in Arms Manufacturing, Uranium Mining, Woodchip Exports, and Beef-Based Agriculture. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 161,966 finches, but there is a significant disparity between incomes, with the richest 10% of citizens earning 515,059 per year while the poor average 38,779, a ratio of 13.3 to 1.

The government's religious works are headed by a New Age guru, military chaplains grow frustrated with their long commutes, Big Brother is still watching even when your big brother is dead, and military doctrine says not to open fire until you see the "beady little eyes" of Johnny Foreigner. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force. Fringillidae's national animal is the chaffinch, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Fringilla.

Fringillidae is ranked 3,607^th in the world and 4^th in Middle Earth for Largest Mining Sector, scoring 14,370.28 on the Blue Sky Asbestos Index.
