Current U.S. HSI-C research snapshot

0.6254

Under the current research model, qualifying household-controlled productive capacity equals approximately 63% of the remaining needs of the modeled U.S. household benchmark.

Reading this index

HSI-C (Household Sovereignty Capacity — modeled) is a modeled capacity measure: what qualifying household-controlled infrastructure could produce, relative to the household needs still purchased from the economy. Maintained continuously. Updated as validated inputs change. HSI is an independent research instrument. It is not a government statistic or a credit product.

What is an HSI snapshot?

An HSI snapshot freezes the sources, assumptions, methodology and calculation used to produce an index value at a specific state of the research. When a validated underlying input changes, the engine produces a new snapshot and compares it with the previous state.

Help build the real-world household dataset

Help us measure what happens in real homes

HSI-C models what household-controlled productive infrastructure could provide. We are building the next dataset from households willing to share real operating results.

Participants will be able to see how their household compares with the broader HSI research model and what currently stands between them and sovereignty parity.

Enrollment is the first step. The household profile, productive stack and operating-observation stages open as each is built, and a personalized profile is not available yet.

Evidence mix

How much of this is observed?

Every input carries an evidence class, and calculated values inherit the weakness of their inputs. A scenario input never becomes observed by passing through a formula. How evidence classes are defined.

Source inputs

  • Observed3 of 3 · 100%

Standing assumptions

  • Scenario1 of 1 · 100%

Assumptions

What remains conditional.

Every temporary assumption carries a reason for existing and the condition that would retire it. Assumptions are meant to expire.

Why it is here
PUMS does not observe energy, capital, task capacity, SCI, or EA. The profile is explicit scenario.
What would replace it
Replace when observed energy, capital, task, SCI, and an approved EA/APWB threshold exist.
