RACED itself cannot be added to your data cart when creating an extract, however, detailed versions of variables you have included (ex: RACED is the detailed version of RACE) are automatically included in your extract. In other words, as long as you add RACE to your extract, you will also have a RACED variable available for analysis in your data.
