Concepts classifying the person into a named category of humans sharing common history, traits, geographical origin or nationality. The ethnicity codes used to represent these concepts are based upon the [Race & Ethnicity - CDC (CDCREC)](https://phinvads.cdc.gov/vads/ViewCodeSystem.action?id=2.16.840.1.113883.6.238) which includes over 900 concepts for representing race and ethnicity of which 43 reference ethnicity. The ethnicity concepts are grouped by and pre-mapped to the 2 OMB ethnicity categories:

* Hispanic or Latino
* Not Hispanic or Latino.

Complies with 2015 Edition Common Clinical Data Set for patient race.

**Context of Use**

### Profile specific implementation guidance

* This Complex Extension for ethnicity allows one or more ethnicity codes of which:
* An [`ethnicity`](SearchParameter-us-core-ethnicity.md) search parameter has been defined for this extension. However, there are no ethnicity search requirements for the Client or Server.

**Usage info**

**Usages:**

* Use this Extension: [US Core Patient Profile](StructureDefinition-us-core-patient.md)
* Examples for this Extension: [Patient/child-example](Patient-child-example.md), [Patient/deceased-example](Patient-deceased-example.md), [Patient/example](Patient-example.md) and [Patient/infant-example](Patient-infant-example.md)

You can also check for [usages in the FHIR IG Statistics](https://packages2.fhir.org/xig/hl7.fhir.us.core|current/StructureDefinition/us-core-ethnicity)

**Changes since version 7.0.0:**

* The resource metadata has changed (description)

* The data elements list has changed

* One or more text definitions, invariants or bindings have changed
