Gender Inequality Index Calculator

Conditional GIIaggregation using independently established compatible three-domain indices, not raw MMR/AFRnormalization, UNDPcountry results or a universal gender-discrimination measure. Positive indices required; caller owns edition-specific transformations.

Description

A normalized gender-inequality aggregation combines supplied reproductive-health, empowerment and labor domain indices.

A normalized gender-inequality aggregation combines supplied reproductive-health, empowerment and labor domain indices.^{[1, 2]}

Its arithmetic stage does not reconstruct the raw indicators or normalization required for an official published index.

When to use Gender Inequality Index Calculator

Use this tool to obtain conditionalGenderInequalityIndex 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 Gender Inequality Index Calculator and understand its results

Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
Enter callerNormalizedFemaleDomainIndices, callerNormalizedMaleDomainIndices, using the field meanings and rules below, then run the tool.
Read result.conditionalGenderInequalityIndex. 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
callerNormalizedFemaleDomainIndices	Caller normalized female domain indices	list of number	Required
callerNormalizedMaleDomainIndices	Caller normalized male domain indices	list of number	Required

Supply exactly three female and three male normalized domain indices, each in (0,1], in the declared reproductive-health, empowerment and labor order. Compute each category's geometric mean, their harmonic mean and the geometric mean of the per-domain arithmetic means. Return one minus harmonic/reference. This aggregation expects the supplied normalized convention and does not transform raw official indicators.

gF=cuberoot(ΠfemaleDomains); gM=cuberoot(ΠmaleDomains); harmonic=2/(1/gF+1/gM); reference=cuberoot(Π((female_i+male_i)/2)); index=1−harmonic/reference

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.conditionalGenderInequalityIndex	One minus category harmonic aggregation divided by the domain-mean geometric reference.	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. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
