The Federal Republic of Mesozoia is a massive, socially progressive nation, ruled by Cenzo Sara with an even hand, and remarkable for its museums and concert halls, anti-smoking policies, and stringent health and safety legislation. The compassionate population of 1.839 billion Mesozoans are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large, socially-minded government juggles the competing demands of Education, Defense, and Environment. It meets to discuss matters of state in the capital city of Cretacea. The average income tax rate is 60.1%, and even higher for the wealthy.

The strong Mesozoian economy, worth 129 trillion Zoic Dollars a year, is broadly diversified and led by the Book Publishing industry, with major contributions from Tourism, Arms Manufacturing, and Retail. State-owned companies are common. Average income is 70,331 Zoic Dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The tax agency is feared more than serial killers and terrorists, the nation has declared its intention to "stretch out", pedants defending Cenzo Sara observe that psychopaths and sociopaths aren't exactly the same thing, and crime suspects are forced to submit to blood testing. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Mesozoia's national animal is the Archaeopteryx, which frolics freely in the nation's many lush forests.

Mesozoia is ranked 207,854^th in the world and 7,743^rd in Osiris for Highest Disposable Incomes, with 28,062.37 Standard Monetary Units.
