An aquarium of American households

Household
Tank

136 million households. One tank. Every fish is shaped by what a household earns, spends, saves and owes.

How it works

A census you can watch swim.

Each fish stands for a slice of U.S. households, drawn from federal survey data on income, spending, savings, debt and wealth. Rich and poor, city and farm, they share the same water. Big fish swim faster. Some carry heavy bellies. A few have fins taller than everyone else's. Big fish rise; small fish sink. Each fish wears a face: savings and cash flow make it smile, debt makes it sweat, and more money helps less than you'd think. And every so often, a billionaire swims through.

Read a fish

Five parts, five numbers.

Every part's area is proportional to dollars, at one rate for the whole tank. A big mouth with a bigger tail is spending more than it takes in; a tiny body means little cash to fall back on. Each fish is thousands of households combined, while each passing billionaire is one person.
