Description
Check age-set membership under a supplied upper-boundary policy.
Anthropological records depend on source-specific labels, observation periods, coding choices and participant context. A ratio, cyclic index or kinship-code offset describes supplied data rather than identifying a social relationship or cultural meaning. Replacing names with aliases does not establish anonymity.
Check age-set membership under a supplied upper-boundary policy.
When to use this tool
Use Age Set Explicit Boundary Membership when checking the stated observation, coding, chronology or record convention.
How to use the tool and how it works
- Enter age, lower, upper, upperInclusive. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read member. Inspect member before interpreting the associated values.
Check age-set membership under a supplied upper-boundary policy. Require nonnegative age/lower and upper > lower; lower is inclusive, upper follows upperInclusive.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| age | Age | Required. Finite number; minimum 0. |
| lower | Lower | Required. Finite number; minimum 0. |
| upper | Upper | Required. Finite number. |
| upperInclusive | Upper Inclusive | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| member | Member | Required. Boolean. |

}Limitations and assumptions
- The boundaries are caller-defined rather than a cultural classification, legal age rule or identity determination.
- 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
Consult the original field records, community context and appropriate ethical/privacy practices for cultural interpretation or disclosure decisions.
