Debt-to-GDP, now

How it's calculated. Live national debt ÷ live GDP (annual rate). Both tick.

* Per person (projected population) divides by the US population projected to now: the official Census Vintage 2025 estimate for July 1, 2025 (341,784,857), projected forward at Census's stated growth rate (343,051,422 at build time). Per tax return filed divides by 162,754,810 individual income tax returns filed in FY2025 (IRS Data Book, Table 1-2); a joint return counts once and returns with zero tax liability are included.
