    Defined Census line items

    Resolution rule

    The eligible category with the highest percentage change from May 2026 to June 2026.

    Deterministic formula

    ((June 2026 SAAR / May 2026 SAAR) - 1) x 100
    1. 1Retrieve the first official Census private-SA workbook that contains a June 2026 preliminary observation.
    2. 2Record the retrieval timestamp, workbook SHA-256, original Census URL, and an immutable Homecastr archive URI.
    3. 3Read the published integer values in millions of dollars SAAR; do not substitute a forecast or later revision.
    4. 4Calculate the month-over-month percentage change for every eligible category without rounding the intermediate result.
    5. 5Resolve to the single maximum-growth category, or Tie when the maximum is exactly shared at source precision.

    Tie and equality policy: The Tie outcome wins only when two or more eligible categories have the same highest growth rate using the Census-published integer values.
