The Holy Empire of Atom 27 is a colossal, socially progressive nation, renowned for its absence of drug laws, complete absence of social welfare, and spontaneously combusting cars. The hard-nosed, hard-working, democratic, devout population of 3.306 billion Atom 27ians 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 tiny, liberal, pro-business, outspoken government is effectively ruled by the Department of Spirituality, with Welfare and Social Policy not funded at all. Citizens pay a flat income tax of 6.9%.

The very strong Atom 27ian economy, worth 204 trillion Nukes a year, is driven almost entirely by the private sector, which is broadly diversified and led by the Soda Sales industry, with major contributions from Gambling, Book Publishing, and Door-to-door Insurance Sales. Average income is 61,936 Nukes, but there is a significant disparity between incomes, with the richest 10% of citizens earning 226,422 per year while the poor average 12,017, a ratio of 18.8 to 1.

Crime is a problem, probably because of the absence of a police force. Atom 27's national animal is the Deathclaw, which can occasionally be seen sifting through garbage in the nation's cities.

Atom 27 is ranked 170,052^nd in the world and 26^th in Capital Wasteland for Largest Populations, with 3.31 billion capita.
