My experience is the reporting on current employees, which I guess is not voluntary. It's not very clear though:

"Self-identification is the preferred method of identifying race/ethnicity information necessary for the EEO-1 Component 1 Report. Employers are required to attempt to allow employees to use self-identification to complete the EEO-1 Component 1 Report. However, if employees decline to self-identify their race/ethnicity, employment records or observer identification may be used. Where records are maintained, it is recommended that they be kept separately from the employee’s basic personnel file or other records available to those responsible for personnel decisions."
