http://hl7.org/fhir/us/core/StructureDefinition/us-core-genderIdentity|8.0.0-ballot

This extension represents an individual's sense of being a man, woman, boy, girl, nonbinary, or something else, ascertained by asking them what that identity is. Systems requiring multiple gender identities and associated dates **SHOULD** use the FHIR R5 [genderIdentity extension](http://hl7.org/fhir/extensions/StructureDefinition-individual-genderIdentity.html). When future versions of US Core are based on FHIR R5, the FHIR R5 extension will supersede this extension.
