It depends on who’s asking and what they’re asking. The Common App does not qualify the prompts so just be honest and check any/all that apply. Each school decides how to use that information.
Some programs and scholarships do qualify what they consider a minority. In those cases, follow their directions.
There are more opinions here than a universal answer, so it’s best to just answer things honestly regardless of what others think. The common app doesn’t use the narrow definition some people use, which is why this seems to be a confusing topic. Many schools don’t either. Overall, you are what you say are. Honor system for the most part. But adcoms aren’t stupid and some may comb the application for further support depending on how they qualify that information.
