The Belles of St Trinian is a gargantuan, orderly nation, notable for its barren, inhospitable landscape, frequent executions, and public floggings. The hard-nosed, hard-working, cynical, humorless population of 22.488 billion St Trinianians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The relatively small, pro-business, well-organized government prioritizes Law & Order, with Defense and Industry also on the agenda, while Welfare and Social Policy receive no funds. Citizens pay a flat income tax of 8.1%.

The powerhouse St Trinianian economy, worth a remarkable 1,341 trillion Pounds a year, is led by the Arms Manufacturing industry, with major contributions from Door-to-door Insurance Sales, Woodchip Exports, and Automobile Manufacturing. Average income is 59,639 Pounds, but there is a large disparity between incomes, with the richest 10% of citizens earning 227,992 per year while the poor average 10,780, a ratio of 21.1 to 1.

Genetic research has been halted, almost half of the child population live rough on the streets, record sales of 'child-whacking sticks' have been recorded, and military spending is on the increase. Crime, especially youth-related, is almost non-existent, thanks to a very well-funded police force. St Trinian's national animal is the Flash Harry, which teeters on the brink of extinction due to widespread deforestation.

St Trinian is ranked 35,541^st in the world and 12^th in The Respected Realms for Most Extreme, scoring 31.46 on the Paul-Nader Subjective Decentrality Index.
