Justice Souter delivered the opinion of the Court.

The Age Discrimination in Employment Act of 1967 (ADEA or Act), 81 Stat. 602, 29 U. S. C. §621 et seq., forbids discriminatory preference for the young over the old. The question in this case is whether it also prohibits favoring the old over the young. We hold it does not.

I

In 1997, a collective-bargaining agreement between petitioner General Dynamics and the United Auto Workers eliminated the company's obligation to provide health benefits to subsequently retired employees, except as to then-current workers at least 50 years old. Respondents (collectively, Cline) were then at least 40 and thus protected by the Act, see 29 U. S. C. §631(a), but under 50 and so without promise of the benefits. All of them objected to the new terms, although some had retired before the change in order to get the prior advantage, some retired afterwards with no benefit, and some worked on, knowing the new contract would give them no health coverage when they were through.

Before the Equal Employment Opportunity Commission (EEOC or Commission) they claimed that the agreement violated the ADEA, because it "discriminate[d against them] ... with respect to ... compensation, terms, conditions, or privileges of employment, because of [their] age," §623(a)(1). The EEOC agreed, and invited General Dynamics and the union to settle informally with Cline.

When they failed, Cline brought this action against General Dynamics, combining claims under the ADEA and state law. The District Court called the federal claim one of "reverse age discrimination," upon which, it observed, no court had ever granted relief under the ADEA. 98 F. Supp. 2d 846, 848 (ND Ohio 2000). It dismissed in reliance on the Seventh Circuit's opinion in Hamilton v. Caterpillar Inc., 966 F. 2d 1226 (1992), that "the ADEA 'does not protect ... the younger against the older,' " id., at 1227 (quoting Karlen v. City Colleges of Chicago, 837 F. 2d 314, 318 (CA7), cert. denied sub nom. Teachers v. City Colleges of Chicago, 486 U. S. 1044 (1988)).

A divided panel of the Sixth Circuit reversed, 296 F. 3d 466 (2002), with the majority reasoning that the prohibition of §623(a)(1), covering discrimination against "any individual ... because of such individual's age," is so clear on its face that if Congress had meant to limit its coverage to protect only the older worker against the younger, it would have said so. Id., at 472. The court acknowledged the conflict of its ruling with earlier cases, including Hamilton and Schuler v. Polaroid Corp., 848 F. 2d 276 (1988) (Breyer, J.), from the First Circuit, but it criticized the cases going the other way for paying too much attention to the "hortatory, generalized language" of the congressional findings incorporated in the ADEA. 296 F. 3d, at 470. The Sixth Circuit drew support for its view from the position taken by the EEOC in an interpretive regulation.1 Id., at 471.

Judge Cole, concurring, saw the issue as one of plain meaning that produced no absurd result, although he acknowledged a degree of tension with O'Connor v. Consolidated Coin Caterers Corp., 517 U. S. 308 (1996), in which this Court spoke of age discrimination as giving better treatment to a "substantially younger" worker. 296 F. 3d, at 472. Judge Williams dissented in preference for Hamilton and the consensus of the federal courts, thinking it "obvious that the older a person is, the greater his or her needs become." 296 F. 3d, at 476.

We granted certiorari to resolve the conflict among the Circuits, 538 U. S. 976 (2003), and now reverse.

II

The common ground in this case is the generalization that the ADEA's prohibition covers "discriminat[ion] ... because of [an] individual's age," 29 U. S. C. §623(a)(1), that helps the younger by hurting the older. In the abstract, the phrase is open to an argument for a broader construction, since reference to "age" carries no express modifier and the word could be read to look two ways. This more expansive possible understanding does not, however, square with the natural reading of the whole provision prohibiting discrimination, and in fact Congress's interpretive clues speak almost unanimously to an understanding of discrimination as directed against workers who are older than the ones getting treated better.

Congress chose not to include age within discrimination forbidden by Title VII of the Civil Rights Act of 1964, §715, 78 Stat. 265, being aware that there were legitimate reasons as well as invidious ones for making employment decisions on age. Instead it called for a study of the issue by the Secretary of Labor, ibid., who concluded that age discrimination was a serious problem, but one different in kind from discrimination on account of race.2 The Secretary spoke of disadvantage to older individuals from arbitrary and stereotypical employment distinctions (including then-common policies of age ceilings on hiring), but he examined the problem in light of rational considerations of increased pension cost and, in some cases, legitimate concerns about an older person's ability to do the job. Wirtz Report 2. When the Secretary ultimately took the position that arbitrary discrimination against older workers was widespread and persistent enough to call for a federal legislative remedy, id., at 21-22, he placed his recommendation against the background of common experience that the potential cost of employing someone rises with age, so that the older an employee is, the greater the inducement to prefer a younger substitute. The report contains no suggestion that reactions to age level off at some point, and it was devoid of any indication that the Secretary had noticed unfair advantages accruing to older employees at the expense of their juniors.

Congress then asked for a specific proposal, Fair Labor Standards Amendments of 1966, §606, 80 Stat. 845, which the Secretary provided in January 1967. 113 Cong. Rec. 1377 (1967); see also Public Papers of the Presidents, Lyndon B. Johnson, Vol. 1, Jan. 23, 1967, p. 37 (1968) (message to Congress urging that "[o]pportunity ... be opened to the many Americans over 45 who are qualified and willing to work"). Extensive House and Senate hearings ensued. See Age Discrimination in Employment: Hearings on H. R. 3651 et al. before the General Subcommittee on Labor of the House Committee on Education and Labor, 90th Cong., 1st Sess. (1967) (hereinafter House Hearings); Age Discrimination in Employment: Hearings on S. 830 and S. 788 before the Subcommittee on Labor of the Senate Committee on Labor and Public Welfare, 90th Cong., 1st Sess. (1967) (hereinafter Senate Hearings). See generally EEOC v. Wyoming, 460 U. S. 226, 229-233 (1983).

The testimony at both hearings dwelled on unjustified assumptions about the effect of age on ability to work. See, e.g., House Hearings 151 (statement of Rep. Joshua Eilberg) ("At age 40, a worker may find that age restrictions become common ... . By age 45, his employment opportunities are likely to contract sharply; they shrink more severely at age 55 and virtually vanish by age 65"); id., at 422 (statement of Rep. Claude Pepper) ("We must provide meaningful opportunities for employment to the thousands of workers 45 and over who are well qualified but nevertheless denied jobs which they may desperately need because someone has arbitrarily decided that they are too old"); Senate Hearings 34 (statement of Sen. George Murphy) ("[A]n older worker often faces an attitude on the part of some employers that prevents him from receiving serious consideration or even an interview in his search for employment").3 The hearings specifically addressed higher pension and benefit costs as heavier drags on hiring workers the older they got. See, e.g., House Hearings 45 (statement of Norman Sprague) (Apart from stereotypes, "labor market conditions, seniority and promotion-from-within policies, job training costs, pension and insurance costs, and mandatory retirement policies often make employers reluctant to hire older workers"). The record thus reflects the common facts that an individual's chances to find and keep a job get worse over time; as between any two people, the younger is in the stronger position, the older more apt to be tagged with demeaning stereotype. Not surprisingly, from the voluminous records of the hearings, we have found (and Cline has cited) nothing suggesting that any workers were registering complaints about discrimination in favor of their seniors.

Nor is there any such suggestion in the introductory provisions of the ADEA, 81 Stat. 602, which begins with statements of purpose and findings that mirror the Wirtz Report and the committee transcripts. Id., §2. The findings stress the impediments suffered by "older workers ... in their efforts to retain ... and especially to regain employment," id., §2(a)(1); "the [burdens] of arbitrary age limits regardless of potential for job performance," id., §2(a)(2); the costs of "otherwise desirable practices [that] may work to the disadvantage of older persons," ibid.; and "the incidence of unemployment, especially long-term unemployment[, which] is, relative to the younger ages, high among older workers," id., §2(a)(3). The statutory objects were "to promote employment of older persons based on their ability rather than age; to prohibit arbitrary age discrimination in employment; [and] to help employers and workers find ways of meeting problems arising from the impact of age on employment." Id., §2(b).

In sum, except on one point, all the findings and statements of objectives are either cast in terms of the effects of age as intensifying over time, or are couched in terms that refer to "older" workers, explicitly or implicitly relative to "younger" ones. The single subject on which the statute speaks less specifically is that of "arbitrary limits" or "arbitrary age discrimination." But these are unmistakable references to the Wirtz Report's finding that "[a]lmost three out of every five employers covered by [a] 1965 survey have in effect age limitations (most frequently between 45 and 55) on new hires which they apply without consideration of an applicant's other qualifications." Wirtz Report 6. The ADEA's ban on "arbitrary limits" thus applies to age caps that exclude older applicants, necessarily to the advantage of younger ones.

Such is the setting of the ADEA's core substantive provision, §4 (as amended, 29 U. S. C. §623), prohibiting employers and certain others from "discriminat[ion] ... because of [an] individual's age," whenever (as originally enacted) the individual is "at least forty years of age but less than sixty-five years of age," §12, 81 Stat. 607.4 The prefatory provisions and their legislative history make a case that we think is beyond reasonable doubt, that the ADEA was concerned to protect a relatively old worker from discrimination that works to the advantage of the relatively young.

Nor is it remarkable that the record is devoid of any evidence that younger workers were suffering at the expense of their elders, let alone that a social problem required a federal statute to place a younger worker in parity with an older one. Common experience is to the contrary, and the testimony, reports, and congressional findings simply confirm that Congress used the phrase "discriminat[ion] ... because of [an] individual's age" the same way that ordinary people in common usage might speak of age discrimination any day of the week. One commonplace conception of American society in recent decades is its character as a "youth culture," and in a world where younger is better, talk about discrimination because of age is naturally understood to refer to discrimination against the older.

This same, idiomatic sense of the statutory phrase is confirmed by the statute's restriction of the protected class to those 40 and above. If Congress had been worrying about protecting the younger against the older, it would not likely have ignored everyone under 40. The youthful deficiencies of inexperience and unsteadiness invite stereotypical and discriminatory thinking about those a lot younger than 40, and prejudice suffered by a 40-year-old is not typically owing to youth, as 40-year-olds sadly tend to find out. The enemy of 40 is 30, not 50. See H. R. Rep. No. 805, 90th Cong., 1st Sess., 6 (1967) ("[T]estimony indicated [40] to be the age at which age discrimination in employment becomes evident"). Even so, the 40-year threshold was adopted over the objection that some discrimination against older people begins at an even younger age; female flight attendants were not fired at 32 because they were too young, ibid. See also Senate Hearings 47 (statement of Sec'y Wirtz) (lowering the minimum age limit "would change the nature of the proposal from an over-age employment discrimination measure"). Thus, the 40-year threshold makes sense as identifying a class requiring protection against preference for their juniors, not as defining a class that might be threatened by favoritism toward seniors.5

The federal reports are as replete with cases taking this position as they are nearly devoid of decisions like the one reviewed here. To start closest to home, the best example is Hazen Paper Co. v. Biggins, 507 U. S. 604 (1993), in which we held there is no violation of the ADEA in firing an employee because his pension is about to vest, a basis for action that we took to be analytically distinct from age, even though it would never occur without advanced years. Id., at 611-612. We said that "the very essence of age discrimination [is] for an older employee to be fired because the employer believes that productivity and competence decline with old age," id., at 610, whereas discrimination on the basis of pension status "would not constitute discriminatory treatment on the basis of age [because t]he prohibited stereotype [of the faltering worker] would not have figured in this decision, and the attendant stigma would not ensue," id., at 612. And we have relied on this same reading of the statute in other cases. See, e.g., O'Connor, 517 U. S., at 313 ("Because the ADEA prohibits discrimination on the basis of age ... the fact that a replacement is substantially younger than the plaintiff is a ... reliable indicator of age discrimination"); Western Air Lines, Inc. v. Criswell, 472 U. S. 400, 409 (1985) ("[T]he legislative history of the ADEA ... repeatedly emphasize[s that] the process of psychological and physiological degeneration caused by aging varies with each individual"). While none of these cases directly addresses the question presented here, all of them show our consistent understanding that the text, structure, and history point to the ADEA as a remedy for unfair preference based on relative youth, leaving complaints of the relatively young outside the statutory concern.

The Courts of Appeals and the District Courts have read the law the same way, and prior to this case have enjoyed virtually unanimous accord in understanding the ADEA to forbid only discrimination preferring young to old. So the Seventh Circuit held in Hamilton, and the First Circuit said in Schuler, and so the District Courts have ruled in cases too numerous for citation here in the text.6 The very strength of this consensus is enough to rule out any serious claim of ambiguity, and congressional silence after years of judicial interpretation supports adherence to the traditional view.7

III

Cline and amicus EEOC proffer three rejoinders in favor of their competing view that the prohibition works both ways. First, they say (as does Justice Thomas, post, at 1-4) that the statute's meaning is plain when the word "age" receives its natural and ordinary meaning and the statute is read as a whole giving "age" the same meaning throughout. And even if the text does not plainly mean what they say it means, they argue that the soundness of their version is shown by a colloquy on the floor of the Senate involving Senator Yarborough, a sponsor of the bill that became the ADEA. Finally, they fall back to the position (fortified by Justice Scalia's dissent) that we should defer to the EEOC's reading of the statute. On each point, however, we think the argument falls short of unsettling our view of the natural meaning of the phrase speaking of discrimination, read in light of the statute's manifest purpose.

A

The first response to our reading is the dictionary argument that "age" means the length of a person's life, with the phrase "because of such individual's age" stating a simple test of causation: "discriminat[ion] ... because of [an] individual's age" is treatment that would not have occurred if the individual's span of years had been longer or shorter. The case for this reading calls attention to the other instances of "age" in the ADEA that are not limited to old age, such as 29 U. S. C. §623(f), which gives an employer a defense to charges of age discrimination when "age is a bona fide occupational qualification." Cline and the EEOC argue that if "age" meant old age, §623(f) would then provide a defense (old age is a bona fide qualification) only for an employer's action that on our reading would never clash with the statute (because preferring the older is not forbidden).

The argument rests on two mistakes. First, it assumes that the word "age" has the same meaning wherever the ADEA uses it. But this is not so, and Cline simply misemploys the "presumption that identical words used in different parts of the same act are intended to have the same meaning." Atlantic Cleaners & Dyers, Inc. v. United States, 286 U. S. 427, 433 (1932). Cline forgets that "the presumption is not rigid and readily yields whenever there is such variation in the connection in which the words are used as reasonably to warrant the conclusion that they were employed in different parts of the act with different intent." Ibid.; see also United States v. Cleveland Indians Baseball Co., 532 U. S. 200, 213 (2001) (phrase "wages paid" has different meanings in different parts of Title 26 U. S. C.); Robinson v. Shell Oil Co., 519 U. S. 337, 343-344 (1997) (term "employee" has different meanings in different parts of Title VII). The presumption of uniform usage thus relents8 when a word used has several commonly understood meanings among which a speaker can alternate in the course of an ordinary conversation, without being confused or getting confusing.

"Age" is that kind of word. As Justice Thomas (post, at 2) agrees, the word "age" standing alone can be readily understood either as pointing to any number of years lived, or as common shorthand for the longer span and concurrent aches that make youth look good. Which alternative was probably intended is a matter of context; we understand the different choices of meaning that lie behind a sentence like "Age can be shown by a driver's license," and the statement, "Age has left him a shut-in." So it is easy to understand that Congress chose different meanings at different places in the ADEA, as the different settings readily show. Hence the second flaw in Cline's argument for uniform usage: it ignores the cardinal rule that "[s]tatutory language must be read in context [since] a phrase 'gathers meaning from the words around it.' " Jones v. United States, 527 U. S. 373, 389 (1999) (quoting Jarecki v. G. D. Searle & Co., 367 U. S. 303, 307 (1961)). The point here is that we are not asking an abstract question about the meaning of "age"; we are seeking the meaning of the whole phrase "discriminate ... because of such individual's age," where it occurs in the ADEA, 29 U. S. C. §623(a)(1). As we have said, social history emphatically reveals an understanding of age discrimination as aimed against the old, and the statutory reference to age discrimination in this idiomatic sense is confirmed by legislative history. For the very reason that reference to context shows that "age" means "old age" when teamed with "discrimination," the provision of an affirmative defense when age is a bona fide occupational qualification readily shows that "age" as a qualification means comparative youth. As context tells us that "age" means one thing in §623(a)(1) and another in §623(f),9 so it also tells us that the presumption of uniformity cannot sensibly operate here.10

The comparisons Justice Thomas urges, post, at 7-12, to McDonald v. Santa Fe Trail Transp. Co., 427 U. S. 273 (1976), and Oncale v. Sundowner Offshore Services, Inc., 523 U. S. 75 (1998), serve to clarify our position. Both cases involved Title VII of the Civil Rights Act of 1964, 42 U. S. C. §2000e et seq., and its prohibition on employment discrimination "because of [an] individual's race ... [or] sex," §2000e-2(a)(1) (emphasis added). The term "age" employed by the ADEA is not, however, comparable to the terms "race" or "sex" employed by Title VII. "Race" and "sex" are general terms that in every day usage require modifiers to indicate any relatively narrow application. We do not commonly understand "race" to refer only to the black race, or "sex" to refer only to the female. But the prohibition of age discrimination is readily read more narrowly than analogous provisions dealing with race and sex. That narrower reading is the more natural one in the textual setting, and it makes perfect sense because of Congress's demonstrated concern with distinctions that hurt older people.

B

The second objection has more substance than the first, but still not enough. The record of congressional action reports a colloquy on the Senate floor between two of the legislators most active in pushing for the ADEA, Senators Javits and Yarborough. Senator Javits began the exchange by raising a concern mentioned by Senator Dominick, that "the bill might not forbid discrimination between two persons each of whom would be between the ages of 40 and 65." 113 Cong. Rec. 31255 (1967). Senator Javits then gave his own view that, "if two individuals ages 52 and 42 apply for the same job, and the employer selected the man aged 42 solely ... because he is younger than the man 52, then he will have violated the act," and asked Senator Yarborough for his opinion. Ibid. Senator Yarborough answered that "[t]he law prohibits age being a factor in the decision to hire, as to one age over the other, whichever way [the] decision went." Ibid.

Although in the past we have given weight to Senator Yarborough's views on the construction of the ADEA because he was a sponsor, see, e.g., Public Employees Retirement System of Ohio v. Betts, 492 U. S. 158, 179 (1989), his side of this exchange is not enough to unsettle our reading of the statute. It is not merely that the discussion was prompted by the question mentioned in O'Connor v. Consolidated Coin Caterers Corp., 517 U. S. 308 (1996), the possibility of a 52-year-old suing over a preference for someone younger but in the over-40 protected class. What matters is that the Senator's remark, "whichever way [the] decision went," is the only item in all the 1967 hearings, reports, and debates going against the grain of the common understanding of age discrimination.11 Even from a sponsor, a single outlying statement cannot stand against a tide of context and history, not to mention 30 years of judicial interpretation producing no apparent legislative qualms. See Consumer Product Safety Comm'n v. GTE Sylvania, Inc., 447 U. S. 102, 118 (1980) ("[O]rdinarily even the contemporaneous remarks of a single legislator who sponsors a bill are not controlling in analyzing legislative history").

C

The third objection relies on a reading consistent with the Yarborough comment, adopted by the agency now charged with enforcing the statute, as set out at 29 CFR §1625.2(a) (2003), and quoted in full, n. 1, supra. When the EEOC adopted §1625.2(a) in 1981, shortly after assuming administrative responsibility for the ADEA, it gave no reasons for the view expressed, beyond noting that the provision was carried forward from an earlier Department of Labor regulation, see 44 Fed. Reg. 68858 (1979); 46 Fed. Reg. 47724 (1981); that earlier regulation itself gave no reasons, see 33 Fed. Reg. 9172 (1968) (reprinting 29 CFR §860.91, rescinded by 46 Fed. Reg. 47724 (1981)).

The parties contest the degree of weight owed to the EEOC's reading, with General Dynamics urging us that Skidmore v. Swift & Co., 323 U. S. 134 (1944), sets the limit, while Cline and the EEOC say that §1625.2(a) deserves greater deference under Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837 (1984). Although we have devoted a fair amount of attention lately to the varying degrees of deference deserved by agency pronouncements of different sorts, see United States v. Mead Corp., 533 U. S. 218 (2001); Christensen v. Harris County, 529 U. S. 576 (2000), the recent cases are not on point here. In Edelman v. Lynchburg College, 535 U. S. 106, 114 (2002), we found no need to choose between Skidmore and Chevron, or even to defer, because the EEOC was clearly right; today, we neither defer nor settle on any degree of deference because the Commission is clearly wrong.

Even for an agency able to claim all the authority possible under Chevron, deference to its statutory interpretation is called for only when the devices of judicial construction have been tried and found to yield no clear sense of congressional intent. INS v. Cardoza-Fonseca, 480 U. S. 421, 446-448 (1987) (citing Chevron, supra, at 843, n. 9). Here, regular interpretive method leaves no serious question, not even about purely textual ambiguity in the ADEA. The word "age" takes on a definite meaning from being in the phrase "discriminat[ion] ... because of such individual's age," occurring as that phrase does in a statute structured and manifestly intended to protect the older from arbitrary favor for the younger.

IV

We see the text, structure, purpose, and history of the ADEA, along with its relationship to other federal statutes, as showing that the statute does not mean to stop an employer from favoring an older employee over a younger one. The judgment of the Court of Appeals is

Reversed.
