The Devil Child of Nico Robin is a titanic, efficient nation, ruled by Miss All Sunday with an even hand, and notable for its strictly enforced bedtime, infamous sell-swords, and spontaneously combusting cars. The hard-nosed, hard-working, humorless population of 15.205 billion Straw Hats are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized, corrupt government juggles the competing demands of Administration, Industry, and Education. It meets to discuss matters of state in the capital city of Thousand Sunny. Citizens pay a flat income tax of 92.0%.

The frighteningly efficient Straw Hat economy, worth a remarkable 5,288 trillion berries a year, is fairly diversified and mostly comprised of black market activity, especially in Information Technology, Retail, Uranium Mining, and Woodchip Exports. Average income is an amazing 347,808 berries, but there is a significant disparity between incomes, with the richest 10% of citizens earning 1,231,131 per year while the poor average 70,945, a ratio of 17.4 to 1.

The government merely sends empty platitudes whenever natural disasters strike foreign nations, whales in captivity live in little more than glorified goldfish bowls, the blood, sweat, and tears of poor Straw Hats make research institutes rich, and citizens need a magnifying glass and color chart to distinguish between nearly identical brand labels. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Nico Robin's national animal is the monkey, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Cards.

Nico Robin is ranked 319,753^rd in the world and 9^th in The Straw Hat Pirates for Largest Insurance Industry, scoring -11.59 on the Risk Expulsion Effectiveness Rating.
