Description
Return the separate shares and exportShare-importShare.
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 the separate shares and exportShare-importShare.
When to use this tool
Use Global Trade Country Share Term when you need a population count or share on a declared inclusion basis.
How to use the tool and how it works
- Enter countryExports, worldExports, countryImports, worldImports. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read exportShare, importShare, shareGap. Use the output convention below.
Require positive world export and import totals and country quantities within each. Return the separate shares and exportShare-importShare.1
| Input field | Meaning and units | Accepted input |

| worldImports | World Imports | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| exportShare | Export Share | Required. Finite number. |
| importShare | Import Share | Required. Finite number. |
| shareGap | Share Gap | Required. Finite number. |

}Limitations and assumptions
- Trade values use compatible currency, period, and coverage bases; these shares are not trade balance amounts, competitiveness measures, or causal effects.
- 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.
