The Belles of St Trinnian is a gargantuan, orderly nation, remarkable for its public floggings, compulsory military service, and smutty television. The hard-nosed, hard-working, cynical, humorless population of 41.812 billion St Trinnian Girls are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The tiny, moralistic, well-organized government juggles the competing demands of Law & Order, Defense, and Industry. Citizens pay a flat income tax of 3.8%.

The frighteningly efficient a St Trinnian Girl economy, worth a remarkable 5,930 trillion Pounds a year, is driven almost entirely by the private sector, which is broadly diversified and led by the Arms Manufacturing industry, with significant contributions from Automobile Manufacturing, Information Technology, and Uranium Mining. Average income is an impressive 141,829 Pounds, but there is a significant disparity between incomes, with the richest 10% of citizens earning 456,720 per year while the poor average 33,340, a ratio of 13.7 to 1.

Genetic researchers have been expelled, owning a tractor is widely regarded as an essential prerequisite to most government positions, citizens are regularly shot for parking on the double-yellow line, and children as young as twelve are conscripted into the armed forces. Crime, especially youth-related, is totally unknown, thanks to a capable police force. St Trinnian's national animal is the Flash Harry, which teeters on the brink of extinction due to widespread deforestation.

St Trinnian is ranked 50,076^th in the world and 1^st in The European Union for Most Advanced Law Enforcement, scoring 5,363.41 on the Orwell Orderliness Index.
