Promoted 2026-08-28 (delegated): the workbooks were re-downloaded and the generator re-run — output byte-identical to the committed file. PERIOD table — understates future longevity improvement, stated at use sites.

The US period life table, 2024 (qx by age and sex) for CY2024 is 2024 years. Source: NCHS, United States Life Tables 2024 (NVSR vol. 75 no. 5), Tables 2–3. Checked against that source on 2026-08-28.
Where does this number come from?
NCHS, United States Life Tables 2024 (NVSR vol. 75 no. 5), Tables 2–3. We record the primary source for every constant our models use, along with the date a person last checked the value against it — in this case 2026-08-28. A figure without a source and a date cannot be told apart from a stale one.
How do I get this figure programmatically?
GET https://worthune.com/api/v1/facts returns the whole registry as JSON — every constant with its value, period, primary source, and check date. No key is required.

We maintain this registry against its primary sources on a best-efforts basis and version every change publicly. It is reference information, not tax or financial advice — verify against the primary source before relying on a figure. Spotted something wrong or out of date? Tell us at support@worthune.com.
