 <p>ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. 
 ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software 
 formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR 
 performed the following processing steps for this data collection:</p>
