<p>Yes, you can pick more than one category.</p>
<p>As far as alignment with a particular community, I think that’s complex. My son’s 1/2 Puerto Rican, 1/2 Caucasian and he’s brown skinned. He does consider himself Puerto Rican but not because he aligns with the Puerto Rican community, per se. His community is multi-racial and he has no alignment with any ethnic community; he aligns with the Christian community, the math community, the music community, etc. if that makes sense. But, he definitely considers himself PR.</p>
