The panel unanimously concludes this case is suitable for decision
without oral argument. See Fed. R. App. P. 34(a)(2).
Woods’ capabilities existed in substantial numbers in the national economy, the ALJ
denied Woods’ claim for disability benefits. The district court affirmed. Woods
appeals. We have jurisdiction under 42 U.S.C. § 405(g), and we review the agency’s
factual findings for substantial evidence. Id. We affirm.
1. Substantial evidence supports the ALJ’s job estimates. The ALJ
adopted its estimates from the testimony of a vocational expert. The expert has
extensive relevant experience, and Woods does not dispute that she is qualified. And
while the expert referenced the Occupational Employment Quarterly, which Woods
claims is unreliable, see Kilpatrick v. Kijakazi, 35 F.4th 1187, 1194 (9th Cir. 2022),
the expert also relied on OccuBrowse+ and Job Browser Pro, the reliability of which
Woods does not dispute. Thus, the expert’s testimony is the type of evidence that
“a reasonable mind might accept” as adequate support for the ALJ’s job estimates.
Biestek v. Berryhill, 587 U.S. 97, 102–03 (2019) (quotation omitted); see also Ford
v. Saul, 950 F.3d 1141, 1160 (9th Cir. 2020).
2. When a claimant submits job estimates that conflict with an expert’s,
Ninth Circuit precedent requires the ALJ to resolve the conflict. Kilpatrick, 35 F.4th
at 1193–94. The ALJ must address conflicts, however, only when the claimant’s
estimates are “significant” and “probative.” Id. Woods did not use all the same
sources or methodology as the expert, and Woods has not shown that he has any
expertise in estimating national job numbers. See id. at 1194; Wischmann v.
2 24-1729
Kijakazi, 68 F.4th 498, 506–07 (9th Cir. 2023). Thus, Woods’ alternative estimates
are not probative, and the ALJ did not need to explain why it credited the expert’s
estimates over Woods’ alternatives.
3. Woods argues that Social Security Ruling 00-4p1 is invalid because it
conflicts with 20 C.F.R. § 404.1566(d). There is no conflict. See Shaibi v. Berryhill,
883 F.3d 1102, 1109 n.6 (9th Cir. 2017). The regulation requires ALJs to take notice
of reliable job estimates, and SSR 00-4p requires ALJs to ensure that expert
testimony is consistent with the Dictionary of Occupational Titles. SSR 00-4p does
not prevent ALJs from taking notice of other reliable job information.
AFFIRMED.

SSR 00-4p has been rescinded, but its replacement is not retroactive. SSR 24-3p.

R. Nelson, J., concurring: U.S. COURT OF APPEALS
Estimating the number of jobs in the national economy is not an exact science.
Ronald Woods argues that absent special justification, it’s unreasonable for
vocational experts to rely on the equal-distribution method. The majority correctly
resolves Woods’ appeal without deciding whether to adopt his rule. I write
separately to explain why we should reject his rule in a future case.
Substantial evidence is evidence that “a reasonable mind might accept as
adequate to support a conclusion.” Biestek v. Berryhill, 587 U.S. 97, 102–03 (2019)
(quotation omitted). Under this standard, vocational expert testimony is “ordinarily
sufficient by itself” to support an agency’s job estimates. Ford v. Saul, 950 F.3d
1141, 1160 (9th Cir. 2020). That’s true even if the expert doesn’t disclose her
methodology or data. Bayliss v. Barnhart, 427 F.3d 1211, 1218 (9th Cir. 2005);
Biestek, 587 U.S. at 105. After all, it’s generally reasonable to credit expert
testimony on matters within the expert’s expertise.
Of course, there are exceptions. Perhaps the expert is unqualified. Or perhaps
the expert uses a facially implausible methodology. In the Seventh Circuit, before
experts may use the equal-distribution method, they must justify that approach.
Chavez v. Berryhill, 895 F.3d 962, 965 (7th Cir. 2018). Otherwise, the Seventh
Circuit deems it unreasonable to credit their equal-distribution estimates. Id.

Woods asks us to apply the Seventh Circuit’s rule here. “Where [Woods] goes
wrong, at bottom, is in pressing for a categorical rule.” Biestek, 587 U.S. at 108.
Determining whether expert testimony is substantial evidence depends on the
specifics of the record and testimony. Id. Because this determination proceeds
“case-by-case,” there is no “categorical rule,” id., that makes expert testimony “per
se unreliable,” Ford, 950 F.3d at 1159.
This case shows why. In some cases, the assumptions underlying the equal-
distribution method are “improbable.” Kilpatrick v. Kijakazi, 35 F.4th 1187, 1193
(9th Cir. 2022). But in other cases, those assumptions make sense. When a labor
statistic is distributed among highly similar job titles, it makes sense to assume that
each job title reflects a roughly equal share of the overall statistic. In other cases,
the expert testimony may have “sufficient indicia of reliability”—e.g., strong
qualifications or experience—that it’s reasonable to credit the testimony even though
the expert never justifies the equal-distribution method. See Biestek, 587 U.S. at
103, 107. In other words, determining whether expert testimony is substantial
evidence depends on the circumstances of the case—and that remains true when it
comes to the equal-distribution method. Woods’ per se rule would hold otherwise.
So in a future case, we should reject his proposed rule.
