The Nomadic Peoples of Overrhill is a colossal, safe nation, remarkable for its barren, inhospitable landscape, compulsory military service, and punitive income tax rates. The cynical, devout population of 7.631 billion Overrhillians are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The enormous, socially-minded government juggles the competing demands of Law & Order, Welfare, and Defense. The average income tax rate is 69.3%, and even higher for the wealthy.

The large but underdeveloped Overrhillian economy, worth 225 trillion Dinars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Uranium Mining industry, with major contributions from Woodchip Exports, Retail, and Furniture Restoration. Average income is 29,518 Dinars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The tenet of free speech is held dear, scientists regularly clone human beings for research purposes, and the country's famous rainforests are being bulldozed by the mining industry. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Overrhill's national animal is the Goat, which teeters on the brink of extinction due to widespread deforestation.

Overrhill is ranked 71,516^th in the world and 155^th in ainulindale for Largest Populations, with 7.63 billion capita.
