Which type of information would typically not be collected at registration?

In the context of event registration, the primary focus is on gathering essential information that helps manage participants effectively and facilitate event logistics. Contact details and payment information are crucial for communication and financial transactions. Employment history might also be relevant depending on the nature of the event, particularly if it relates to specific professional development or networking opportunities.

However, collecting ethnicity is generally not typical during the registration process for most events. While there are certain types of events or studies that might require demographic data, in generic registration scenarios, this information is often considered sensitive and may not be necessary for the event's operational success. Therefore, it is less likely to be collected as a standard practice at registration, as it does not contribute to the fundamental logistical needs of the event.
