Description
Return revised-original and add duplicatesRemoved minus lateAdded for unexplainedDelta.
Population and eligibility summaries depend on who enters the numerator and denominator. Weighted shares can differ from unweighted averages, and source coverage is a different property from representativeness or outcome quality.
Return revised-original and add duplicatesRemoved minus lateAdded for unexplainedDelta.
When to use this tool
Use Migration Flow Revision Delta when you need a population count or share on a declared inclusion basis.
How to use the tool and how it works
- Enter original, revised, duplicatesRemoved, lateAdded. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read publishedDelta, unexplainedDelta. Use the output convention below.
Require nonnegative integer original, revised, duplicatesRemoved, and lateAdded. Return revised-original and add duplicatesRemoved minus lateAdded for unexplainedDelta.1

}Limitations and assumptions
- This is revision accounting under a supplied classification; source coverage, migration definitions, population identities, and causes of remaining differences are not established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Reconcile the source population and weighting scheme before comparison. Use a complete statistical analysis when sampling uncertainty, demographic interpretation, or causal explanation matters.
