It describes a phenotype, or rather class of phenotypes; and that phenotype is associated, both directly and indirectly, with some particular genetic markers.
The wording choices of the US Census fail at being normative for anthropology.
Yet it is the primary classes used by the US Census which that particular study uses...
The "race" pseudotaxon the US census use isn't scientifically sound and mostly a politically-determined characterization
... the subdivisions they use correspond to clusters of ancestry. The particular choice of categories is political; but the divisions can be easily be made genetically, and the study does just that.
When they look very closely, they can also see two distinct East Asian subclusters, Japanese and Chinese, but they couldn't see clusters within "white non-Hispanic," "Hispanic," and "African American."
Anyway, if you want to claim administrative statements are normative for anthropology, here:European Union, Council Directive 2000/43/EC wrote:"The European Union rejects theories which attempt to determine the existence of separate human races."
That's very much pure politics.
Speaking about the method itself, considering how self-identification is mostly a result of non-self-identification by phenotypical groups, and how phenotypes are influenced by genotypes, no major surprise.
Yes. No major surprise.

So?
All race is, ultimately, is a categorization within the human species.
Wrong. As I said, the races are paraphyletic groupings. Worse, some are even polyphyletic. The races themselves are not clusters, but themselves contain dozens of different clines that spread across the entire human population. The races are nothing more than attempts on our part to draw lines in the sand where no such lines actually exist.
Lines which, nevertheless, many people are reluctant to marry across; and lines which are visible in the genetic clusters.
So. People observe, and react to, the clusters of phenotypical differences. We can just as easily use a computer analysis to sort people into their appropriate categories. What more is needed for the line to exist, than the fact that it is visible to a machine told to look for genetic clustering into populations, visible to humans interacting with each other, and pretty damn well has a real effect on how people treat you?
Is it that hard to say "I think it's only a cosmetic difference," that you have to say "WE CAN'T DRAW THIS LINE EVEN THOUGH WE DO DRAW THE LINE AND A SMART COMPUTER DOING GENETIC ANALYSIS WOULD ALSO DRAW THAT LINE AND MAYBE A COUPLE MORE DEPENDING ON HOW SENSITIVE WE TELL IT TO BE?"
Because I'd rather just say "Hey, the differences between races are pretty small and insignificant, wow look at how much other species vary," and therefore not look like an ostrich.
