Special treatment of sensitive data is required in certain jurisdictions, such as mainland China where information relating to race/ ethnicity is subject to more stringent requirements. Companies may consider whether it is sufficient to collect anonymised data since fully anonymised data may not fall within the data privacy regimes and employees are generally more willing to give accurate responses (i.e., better data quality). Even if data is collected anonymously, unique combinations and overly small sample sizes should be avoided (e.g., if there is only one black female employee in the company and the survey identifies a person as black, the associated data will not be anonymous).
