Opinion of the Court
Duchin’s conclusion was based on an assessment of the map
as a whole rather than District 1 in particular. A state-wide
analysis cannot show that District 1 was drawn based on
race. See Bethune-Hill, 580 U. S., at 191 (“[T]he basic unit
of analysis for racial gerrymandering claims . . . is the district”); Alabama Legislative Black Caucus, 575 U. S., at
262–263 (a racial-gerrymandering claim “does not apply to
a State considered as an undifferentiated ‘whole’ ”). Given
these serious problems, it is no wonder that the challengers
cite Dr. Duchin’s report only in support of their racial votedilution claim. It has no probative force with respect to
their racial-gerrymandering claim regarding District 1’s
boundaries.
To sum up our analysis so far, no direct evidence supports
the District Court’s finding that race predominated in the
design of District 1 in the Enacted Plan. The circumstantial
evidence falls far short of showing that race, not partisan
preferences, drove the districting process, and none of the
expert reports offered by the Challengers provides any significant support for their position. 11

11 The dissent, by contrast, would make it virtually impossible to show
clear error in a case like this. The dissent agrees that a plaintiff raising
a racial-gerrymandering claim bears a “demanding burden.” Post, at 10
(opinion of KAGAN, J.). But according to the dissent’s view, clear-error
review means that this burden vanishes on appeal because a plaintiff ’s
“hardest job should be done” once it prevails before a three-judge district
court. Ibid. That misses the point. In assessing whether a finding is
clearly erroneous, it is important to keep in mind the standard of proof
that the district court was required to apply. It is hornbook law, after
all, that we must ask on appeal whether the “factfinder in the first instance made a mistake in concluding that a fact had been proven under
the applicable standard of proof.” Concrete Pipe & Products of Cal., Inc.
v. Construction Laborers Pension Trust for Southern Cal., 508 U. S. 602,
622–623 (1993) (emphasis added); see also H. Edwards & L. Elliott, Federal Standards of Review 26 (3d ed. 2018) (“[I]n applying the clearly erroneous standard, a reviewing court must take account of the standard
of proof informing the trial court’s factual finding”). Once our task is
framed properly, we can easily conclude for the reasons that follow that
