The Third Doctor of Jon Pertwee is a mammoth, efficient nation, ruled by The Third Doctor with an iron fist, and notable for its rum-swilling pirates, enslaved workforce, and suspicion of poets. The hard-nosed, cynical population of 7.137 billion Gallifreyans 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 medium-sized, corrupt government juggles the competing demands of Education, Industry, and Administration. It meets to discuss matters of state in the capital city of UNIT HQ. The average income tax rate is 37.8%.

The frighteningly efficient Gallifreyan economy, worth 739 trillion sonic screwdrivers a year, is fairly diversified and led by the Retail industry, with significant contributions from Gambling, Arms Manufacturing, and Soda Sales. Black market activity is rampant. Average income is an impressive 103,676 sonic screwdrivers, with the richest citizens earning 5.0 times as much as the poorest.

Locally produced computer games are being released faster than gamers can play them, military chaplains grow frustrated with their long commutes, major cities shut down as their local sports team takes to the field every day, and tourists flock to see the giant stone carvings of historical leaders at Mount Rushless. Crime, especially youth-related, is almost non-existent, thanks to a capable police force and progressive social policies in education and welfare. Jon Pertwee's national animal is the sea devil, which can occasionally be seen avoiding garbage in the nation's murky oceans, and its national religion is Science.

Jon Pertwee is ranked 70,111^th in the world and 5^th in The Doctors for Largest Insurance Industry, scoring 3,202.51 on the Risk Expulsion Effectiveness Rating.
