Methodology & refresh

Charts pull from public APIs at build time (FRED for the balance sheet and CPI). If a source is unavailable during a build, the site falls back to a committed snapshot anchored to the last-published values — so a chart is never empty. Each chart shows its "as of" date.

Purchasing-power figures follow the CPI-based approach used by MeasuringWorth and the BLS inflation calculator. Historical dates and statutory figures are fixed and sourced as above.
