Would she count as a mixed-race woman?

Every woman is a "mixed race woman." Every man too. There are no "pure" races, those ended millions of years ago. For people to even think about "mixed race" in humans is to show they have no understanding of "race" in the modern world.

I'm assuming by mixed race you mean someone with one black and one white parent?
By this definition no she isn't and couldn't pass for one either, she is white.
I believe the character in the film version is white anyway, regardless of the character in the book.

That would be a very shallow way to look at "what race"?

Although all races share over 99% of the same genetic material, the classification and division of races is largely subjective, and all races belong to the same species - Homo sapiens. Scientifically, races are defined as a group of people that are separated and grouped together due to the fact that they have common inherited traits that distinguishes them from other groups.

The notion of race is also divided based on geographic separation, social and cultural differences and distinguished physical differences. Human typologies are commonly differentiated based on the following physical traits:

skin color
hair texture
jaw size
facial angle
cranial capacity
frontal lobe mass
brain mass
brain surface fissures

These physical attributes do not necessarily have a strong correlation with genetic variations. As a result, the United Nations has opted to drop the term "race" and replace it with "ethnic groups" instead . According to a 1998 study published in the Scientific American, there are more than 5,000 ethnic groups in the world.

So, as I commented above, trying to discuss "race" and "mixed-race" is to discuss a now defunct way of looking at different types of humans.

Sometimes I think we're alone in the universe, and sometimes not.

She looks Sicilian/moorish

just saw her in Jason Bourne and i thought she was part Indian or Pakistan.

I read she is part Finnish. I read that the Fins have a mixture of Turkic and Scandinavian genealogy. Maybe she favors the Turkic part of her heritage.

I believe she's 1/4 Finnish, yes. I never once thought she looked like someone from India or Pakistan, her features are completely different. I doubt everyone in Sweden is blonde and tall.

Mixed race? No. Mixed ethnicity ? Yes. She passes as a Southern European or a Middle Easterner. That's about it. She definitely doesn't pass for South Asian or black.
