Data sources
Every page cites the source and date of the data behind it. Series in use:

| U.S. inflation (CPI-U) | BLS via FRED | monthly |
| UK / Eurozone / India / China CPI | ONS, Eurostat, FRED (OECD) | monthly |
| S&P 500 (price index) | closing prices (not exportable) | daily |
| Bitcoin, Ethereum | closing prices (not exportable) | daily |

| Exchange rates (G10) | FRED (H.10) | monthly |
| U.S. home prices (per m²) | Redfin | monthly |
We chose official and primary series wherever they exist: consumer-price indices from national statistics offices, exchange rates from the Federal Reserve, home prices from Redfin's sold-listing data. Market closing prices are shown but not redistributed. Nothing here is a proprietary estimate — every figure is computed from a published series and dated on the page.
We display computed results with attribution — we do not redistribute raw series. Data is collected by the Radar Perene pipeline and consumed here read-only.
