When asked about a person's race, respondents are now allowed to select more than one racial category when answering most surveys. As a result, while some select a single race, such as Asian, others may select multiple races, such as Asian and White. Hence, when looking at the "Asian" population, you might want to include those that also coupled Asian with any other race.
The graphs below were made to give you an idea about what proportion of each racial category includes those selecting THAT race plus others.
