I guess I'm interested in what fraction of people identify strongly with a certain ethnic group. This is given the assumption that people who do not identify strongly with a single ethnic group (e.g. multi-heritage) will select "None of the Above". But the poll is severely limited by the fact there are only 30 options, and that some people may be answering more according to their National Identity or Cultural Identity rather than Ethnic Identity. But it's a little difficult, isn't it, to design a poll like this? I feel like the only interpretable information is the exclude all the ambiguous choices like English/Spanish/etc.
