OECD Modified Equivalisation Scale Calculator
Conventional modified OECDhousehold scale:1first adult,.5each additional14+person,.3each under14person. Caller independently establishes household/age classification; not actual costs or household wellbeing.
Description
The modified OECD equivalence scale represents household size with age-dependent weights.
When to use OECD Modified Equivalisation Scale Calculator
Use this tool to obtain modifiedOecdEquivalenceUnits from the supplied records using the stated calculation. Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
How to use OECD Modified Equivalisation Scale Calculator and understand its results
- Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
- Enter firstAdultCount, additionalAge14PlusCount, under14Count, using the field meanings and rules below, then run the tool.
- Read result.modifiedOecdEquivalenceUnits. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| firstAdultCount | First adult count | number | Required |
| additionalAge14PlusCount | Additional age14 plus count | number | Required |
| under14Count | Under14 count | number | Required |
Require first-adult count exactly one, and integer additional-age-fourteen-plus and under-fourteen counts from zero through one hundred each. Apply the fixed modified-OECD weights. Return equivalence units without calculating household income, determining ages or validating household composition.
equivalenceUnits=1+0.5×additionalAge14Plus+0.3×under14 Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.modifiedOecdEquivalenceUnits | One plus half-weighted additional age-fourteen-plus members and three-tenths-weighted younger members. | number |

}Limitations and assumptions
Population definitions, survey design, calibration and observation coverage are independently established. A result describes the supplied record or conditional model without demonstrating causation, validating an instrument or supplying representative population evidence.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use At-Risk-of-Poverty 60% Median Rate Calculator: A sixty-percent-median poverty comparison uses a supplied matched median and equivalized incomes. For a complementary comparison, use Relative Median Income Gap Calculator: A relative median income gap relates an independently verified poor-group median to a poverty threshold.
