Competition authorities require disaggregated data to understand when and how diverse groups of people are harmed disproportionately. Gendered data is a good starting point. However, having a broader set of data is even better, as additional demographic data can be used to control for other characteristics.
Ask for disaggregated data related to consumer facing markets whenever possible, including transaction level data. If you are not sure where to start, ask the company for a list of data they collect on consumers or competitors.
Considering privacy concerns, it is good to get de‑identified data where only characteristics are listed, rather than names.
For public records where names are available (e.g. online reviews), authorities can use predictive naming tools to infer gender when it is otherwise unavailable.
Request information about consumer profiling or if and how the company distinguishes between types of consumers.
To gather data, include gender in published decisions whenever possible, including characteristics and relationship of cartel participants.
Consult with other law enforcement agencies to see if they gather and use gender-based data. The data itself or methodologies to gather data may be useful.
