The Commonwealth of Celtic Britain is a gargantuan, efficient nation, remarkable for its frequent executions, keen interest in outer space, and suspicion of poets. The hard-nosed, cynical, humorless, devout population of 14.553 billion Celts are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The large government prioritizes Education, with Industry, Environment, and Welfare also on the agenda, while Defense receives no funds. Citizens pay a flat income tax of 45.7%.

The powerhouse Celtic economy, worth a remarkable 1,000 trillion pounds a year, is fairly diversified and led by the Beef-Based Agriculture industry, with significant contributions from Furniture Restoration, Trout Farming, and Book Publishing. Black market activity is extensive. State-owned companies are common. Average income is 68,775 pounds, but there is a significant disparity between incomes, with the richest 10% of citizens earning 254,027 per year while the poor average 13,130, a ratio of 19.3 to 1.

Travellers are often forcibly evicted by torch-bearing mobs, appendix transplant figures have recently doubled, clergy who start talking about politics are forced to take a holy vow of silence, and reflection is vital for badly behaved politicians. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Celtic Britain's national animal is the dragon, which soars majestically through the nation's famously clear skies.

Celtic Britain is ranked 244,938^th in the world and 33^rd in Lennart for Most Advanced Public Transport, scoring 470.26 on the Societal Mobility Rating.
