• Do we want race variables as one column or multiple for each race?

[pvaswani]

Are participants documented as multiple races? If not, one column would be prefered in my opinion. If selection of multiple races is possible, then one column per race may be necessary?

[alex-reardon]

Yes selection of multiple races does occur.
