Cohabitation Rate Calculator
Actual cohabitation percentage. Independently matched complete reference population/period/definition; not automated person classification, causal effect, safety or individual identity.
Description
A cohabitation percentage depends on the relationship and eligibility definitions used in a count.
A cohabitation percentage depends on the relationship and eligibility definitions used in a count.1
Both numerator and denominator must refer to the same adult population. The calculation and input requirements are explained below.
When to use Cohabitation Rate Calculator
Enter an integer numerator from 0 to 1000000 and matching integer denominator from 1 to 1000000 using the exact field definitions below.
How to use Cohabitation Rate Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Cohabitation Rate Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualQualifiedCohabitingEligiblePeople | Actual Qualified Cohabiting Eligible People. Use the units and matching context stated in the calculation below. | number | Required; integer 0–1000000; finite; other constraints below |
| actualEligibleAdultPopulation | Actual Eligible Adult Population. Use the units and matching context stated in the calculation below. | number | Required; integer 1–1000000; finite; other constraints below |
Enter an integer numerator from 0 to 1000000 and matching integer denominator from 1 to 1000000 using the exact field definitions below. The numerator must not exceed the denominator. Divide numerator by denominator and multiply by 100. The result is a percentage. Population, eligibility, period and record classification must be established before entering counts; the tool only checks and calculates the supplied observations.
rate=100*numerator/denominator Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Numeric result under the formula and output units explained above. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
