The Rogue Nation of Sans Underale is a massive, genial nation, notable for its smutty television, enforced nudity, and punitive income tax rates. The compassionate, cynical population of 1.944 billion Sans Underaleans are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

It is difficult to tell where the omnipresent, socially-minded, well-organized government stops and the rest of society begins, but it juggles the competing demands of Welfare, Healthcare, and Education. The average income tax rate is 80.7%, and even higher for the wealthy.

The sizeable but sluggish Sans Underalean economy, worth 45.7 trillion caats a year, is driven almost entirely by government activity, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Basket Weaving industry, with significant contributions from Book Publishing, Woodchip Exports, and Uranium Mining. State-owned companies are the norm. Average income is 23,508 caats, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Rubber stamp emojis are the new craze, public nudity is compulsory, same-sex marriages are increasingly common, and scientists regularly clone human beings for research purposes. Crime is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Sans Underale's national animal is the cat, which frolics freely in the nation's many lush forests.

Sans Underale is ranked 192,028^th in the world and 7,775^th in Balder for Largest Publishing Industry, scoring 345.01 on the Bella Potter Productivity e-Index.
