[201]*201Mr. Justice Brennan
announced the judgment of the Court and delivered an opinion in which Mr. Justice White, Mr. Justice Marshall, and Mr. Justice Powell joined.
Under the Federal Old-Age, Survivors, and Disability Insurance Benefits (OASDI) program, 42 U. S. C. §§ 401-431 (1970 ed. and Supp. V), survivors’ benefits based on the earnings of a deceased husband covered by the Act are payable to his widow. Such benefits on the basis of the earnings of a deceased wife covered by the Act are payable to the widower, however, only if he “was receiving at least one-half of his support” from his deceased wife.1 The question in this case is [202]*202whether this gender-based distinction violates the Due Process Clause of the Fifth Amendment.
A three-judge District Court for the Eastern District of New York held that the different treatment of men and women mandated by § 402 (f)(1)(D) constituted invidious discrimination against female wage earners by affording them less protection for their surviving spouses than is provided to male employees, 396 F. Supp. 308 (1975).2 We noted probable jurisdiction. 424 U. S. 906 (1976). We affirm.
I
Mrs. Hannah Goldfarb worked as a secretary in the New York City public school system for almost 25 years until [203]*203her death in 1968. During that entire time she paid in full all social security taxes required by the Federal Insurance Contributions Act, 26 U. S. C. §§ 3101-3126. She was survived by her husband, Leon Goldfarb, now aged 72, a retired federal employee. Leon duly applied for widower’s benefits. The application was denied with the explanation:
“You do not qualify for a widower’s benefit because you do not meet one of the requirements for such entitlement. This requirement is that you must have been receiving at least one half support from your wife when she died.” 3
The District Court declared § 402 (f)(1)(D) unconstitutional primarily on the authority of Weinberger v. Wiesenfeld, 420 U. S. 636 (1975), stating:
“[Section 402 (f)(1)(D)] and its application to this plaintiff, ‘deprive women of protection for their families which men receive as a result of their employment.’ Weinberger v. Wiesenfeld, 420 U.S. 636, 645 . . . (1975). See also Frontiero v. Richardson, 411 U. S. 677 . . . (1973)
“Whatever may have been the ratio of contribution to family expenses of the Goldfarbs while they both [204]*204worked, Mrs. Goldfarb was entitled to the dignity of knowing that her social security tax would contribute to their joint welfare when the couple or one of them retired and to her husband's welfare should she predecease him. She paid taxes at the same rate as men and there is not the slightest scintilla of support for the proposition that working women are less concerned about their spouses’ welfare in old age than are men.” 396 F. Supp., at 308-309.
II
The gender-based distinction drawn by § 402 (f)(1)(D)—burdening a widower but not a widow with the task of proving dependency upon the deceased spouse—presents an equal protection question indistinguishable from that decided in Weinberger v. Wiesenfeld, supra. That decision and the decision in Frontiero v. Richardson, 411 U. S. 677 (1973), plainly require affirmance of the judgment of the District Court.4
The statutes held unconstitutional in Frontiero provided increased quarters allowance and medical and dental benefits to a married male member of the uniformed Armed Services whether or not his wife in fact depended on him, while a married female service member could only [205]*205receive the increased benefits if she in fact provided over one-half of her husband’s support. To justify the classification, the Secretary of Defense argued: “[A]s an empirical matter, wives in our society frequently are dependent upon their husbands, while husbands rarely are dependent upon their wives. Thus, . . . Congress might reasonably have concluded that it would be both cheaper and easier simply conclusively to presume that wives of male members are financially dependent upon their husbands, while burdening female members with the task of establishing dependency in fact.” 411 U. S., at 688-689. But Frontiero concluded that, by according such differential treatment to male and female members of the uniformed services for the sole purpose of achieving administrative convenience, the challenged statute violated the Fifth Amendment. See Reed v. Reed, 404 U. S. 71, 76 (1971); Stanley v. Illinois, 405 U. S. 645, 656-657 (1972); cf. Schlesinger v. Ballard, 419 U. S. 498, 506-507 (1975).
Weinberger v. Wiesenfeld, like the instant case, presented the question in the context of the OASDI program. There the Court held unconstitutional a provision that denied father’s insurance benefits to surviving widowers with children in their care, while authorizing similar mother’s benefits to similarly situated widows. Paula Wiesenfeld, the principal source of her family’s support, and covered by the Act, died in childbirth, survived by the baby and her husband Stephen. Stephen applied for survivors’ benefits for himself and his infant son. Benefits were allowed the baby under 42 U. S. C. § 402 (d) (1970 ed., Supp. III), but denied the father on the ground that “mother’s benefits” under § 402 (g) were available only to women. The Court reversed, holding that the gender-based distinction made by § 402 (g) was “indistinguishable from that invalidated in Frontiero,” 420 U. S., at 642, and therefore:
“[While] the notion that men are more likely than women [206]*206to be the primary supporters of their spouses and children is not entirely without empirical support, . . . such a gender-based generalization cannot suffice to justify the denigration of the efforts of women who do work and whose earnings contribute significantly to their families’ support.
“Section 402 (g) clearly operates, as did the statutes invalidated by our judgment in Frontiero, to deprive women of protection for their families which men receive as a result of their employment. Indeed, the classification here is in some ways more pernicious. . . . [I]n this case social security taxes were deducted from Paula’s salary during the years in which she worked. Thus, she not only failed to receive for her family the same protection which a similarly situated male worker would have received, but she also was deprived of a portion of her own earnings in order to contribute to the fund out of which benefits would be paid to others.” Id., at 645.
Precisely the same reasoning condemns the gender-based distinction made by § 402 (f)(1)(D) in this case. For that distinction, too, operates “to deprive women of protection for their families which men receive as a result of their employment” : social security taxes were deducted from Hannah Goldfarb’s salary during the quarter century she worked as a secretary, yet, in consequence of § 402 (f)(1)(D), she also “not only failed to receive for her [spouse] the same protection which a similarly situated male worker would have received [for his spouse] but she also was deprived of a portion of her own earnings in order to contribute to the fund out of which benefits would be paid to others.” Wiesenfeld thus inescapably compels the conclusion reached by the District Court that the gender-based differentiation created by § 402 (f)(1)(D)—that results in the efforts of female workers required to pay social security taxes producing less pro[207]*207tection for their spouses than is produced by the efforts of men—is forbidden by the Constitution, at least when supported by no more substantial justification than “archaic and overbroad” generalizations, Schlesinger v. Ballard, supra, at 508, or “ ‘old notions' ” Stanton v. Stanton, 421 U. S. 7, 14 (1975), such as “assumptions as to dependency,” Weinberger v. Wiesenfeld, supra, at 645, that are more consistent with “the role-typing society has long imposed,” Stanton v. Stanton, supra, at 15, than with contemporary reality. Thus § 402 (f)(1)(D) “‘[b]y providing dissimilar treatment for men and women who are . . . similarly situated . . . violates the [Fifth Amendment].’ Reed v. Reed, 404 U. S. 71, 77. . . .” Weinberger v. Wiesenfeld, supra, at 653.
III
Appellant, however, would focus equal protection analysis, not upon the discrimination against the covered wage earning female, but rather upon whether her surviving widower was unconstitutionally discriminated against by burdening him but not a surviving widow with proof of dependency. The gist of the argument is that, analyzed from the perspective of the widower, “the denial of benefits reflected the congressional judgment that aged widowers as a class were sufficiently likely not to be dependent upon their wives that it was appropriate to deny them benefits unless they were in fact dependent.” Brief for Appellant 12.
But Weinberger v. Wiesenfeld rejected the virtually identical argument when appellant’s predecessor argued that the statutory classification there attacked should be regarded from the perspective of the prospective beneficiary and not from that of the covered wage earner. The Secretary in that case argued that the “pattern of legislation reflects the considered judgment of Congress that the ‘probable need’ for financial assistance is greater in the case of a widow, with young children to maintain, than in the case of similarly situ[208]*208ated males.” Brief for Appellant in No. 73-1892, O. T. 1974, p. 14. The Court, however, analyzed the classification from the perspective of the wage earner and concluded that the classification was unconstitutional because “benefits must be distributed according to classifications which do not without sufficient justification differentiate among covered employees solely on the basis of sex.” 420 U. S., at 647. Thus, contrary to appellant’s insistence, Brief for Appellant 12, Wiesenfeld is “dispositive here.”
From its inception, the social security system has been a program of social insurance. Covered employees and their employers pay taxes into a fund administered distinct from the general federal revenues to purchase protection against the economic consequences of old age, disability, and death. But under § 402 (f)(1)(D) female insureds received less protection for their spouses solely because of their sex. Mrs. Goldfarb worked and paid social security taxes for 25 years at the same rate as her male colleagues, but because of § 402 (f)(1)(D) the insurance protection received by the males was broader than hers. Plainly then § 402 (f)(1)(D) disadvantages women contributors to the social security system as compared to similarly situated men.5 The section then “impermissibly discriminates against a female wage earner because it provides her family less protection than it provides that of a male wage earner, even though the family needs may be identical.” Wiesenfeld, supra, at 654-655 (Powell, J., concur[209]*209ring). In a sense, of course, both the female wage earner and her surviving spouse are disadvantaged by operation of the statute, but this is because “Social Security is designed . . . for the protection of the family,” 420 U. S., at 654 (Powell, J., concurring),6 and the section discriminates against one particular category of family—that in which the female spouse is a wage earner covered by social security.7 Therefore decision of the equal protection challenge in this case cannot focus solely on the distinction drawn between widowers and widows but, as Wiesenfeld held, upon the gender-based discrimination against covered female wage earners as well.8
[210]*210IV
Appellant’s emphasis upon the sex-based distinction between widow and widower as recipients of benefits rather than that between covered female and covered male employees also emerges in his other arguments. These arguments have no merit.
A
We accept as settled the proposition argued by appellant that Congress has wide latitude to create classifications that allocate noncontractual benefits under a social welfare program. Weinberger v. Salfi, 422 U. S. 749, 776-777 (1975); Flemming v. Nestor, 363 U. S. 603, 609-610 (1960). It is generally the case, as said, id., at 611:
“Particularly when we deal with a withholding of a noncontractual benefit under a social welfare program such as [Social Security], we must recognize that the Due Process Clause can be thought to interpose a bar only if the statute manifests a patently arbitrary classification, utterly lacking in rational justification.”
See also Weinberger v. Salfi, supra, at 768-770; Richardson v. Belcher, 404 U. S. 78, 81, 84 (1971); Dandridge v. Williams, 397 U. S. 471, 485-486 (1970).
But this “does not, of course, immunize [social welfare legislation] from scrutiny under the Fifth Amendment.” Richardson v. Belcher, supra, at 81. The Social Security Act is permeated with provisions that draw lines in classifying those who are to receive benefits. Congressional decisions in this regard are entitled to deference as those of the institution charged under our scheme of government with the primary responsibility for making such judgments in light of competing policies and interests. But “[t]o withstand constitutional challenge, . . . classifications by gender must serve important governmental objectives and must be substantially related to [211]*211the achievement of those objectives." Craig v. Boren, 429 U. S. 190, 197 (1976).9 Such classifications, however, have frequently been revealed on analysis to rest only upon “old notions” and “archaic and overbroad" generalizations, Stanton v. Stanton, 421 U. S., at 14; Schlesinger v. Ballard, 419 U. S., at 508; cf. Mathews v. Lucas, 427 U. S. 495, 512-513 (1976), and so have been found to offend the prohibitions against denial of equal protection of the law. Reed v. Reed, 404 U. S. 71 (1971); Frontiero v. Richardson, 411 U. S. 677 (1973); Weinberger v. Wiesenfeld, 420 U. S. 636 (1975); Stanton v. Stanton, supra; Craig v. Boren, supra. See also Stanley v. Illinois, 405 U. S. 645 (1972); Taylor v. Louisiana, 419 U. S. 522 (1975).
Therefore, Wiesenfeld, supra, at 646-647, expressly rejected the argument of appellant’s predecessor, relying on Flemming v. Nestor, that the “noncontractual” interest of a covered employee in future social security benefits precluded any claim of denial of equal protection. Rather, Wiesenfeld held that the fact that the interest is “non-contractual" does not mean that “a covered employee has [212]*212no right whatever to be treated equally with other employees as regards the benefits which flow from his or her employment," nor does it “sanction differential protection for covered employees which is solely gender based.” 420 U. S., at 646. On the contrary, benefits “directly related to years worked and amount earned by a covered employee, and not to the need of the beneficiaries directly,” like the employment-related benefits in Frontiero, “must be distributed according to classifications which do not without sufficient justification differentiate among covered employees solely on the basis of sex.” 420 U. S., at 647.
B
Appellant next argues that Frontiero and Wiesenfeld should be distinguished as involving statutes with different objectives from § 402 (f)(1)(D). Rather than merely enacting presumptions designed to save the expense and trouble of determining which spouses are really dependent, providing benefits to all widows, but only to such widowers as prove dependency, § 402 (f)(1)(D), it is argued, rationally defines different standards of eligibility because of the differing social welfare needs of widowers and widows. That is, the argument runs, Congress may reasonably have presumed that nondependent widows, who receive benefits, are needier than nondependent widowers, who do not, because of job discrimination against women (particularly older women), see Kahn v. Shevin, 416 U. S. 351, 353-354 (1974), and because they are more likely to have been more dependent on their spouses. See Wiesenfeld, 420 U. S., at 645; Kahn v. Shevin, supra, at 354 n. 7.10
But “inquiry into the actual purposes” of the discrimina[213]*213tion, Wiesenfeld, supra, at 648, proves the contrary. First, § 402 (f)(1)(D) itself is phrased in terms of dependency, not need. Congress chose to award benefits, not to widowers who could prove that they are needy, but to those who could prove that they had been dependent on their wives for more than one-half of their support. On the face of the statute, dependency, not need, is the criterion for inclusion.
Moreover, the general scheme of OASDI shows that dependence on the covered wage earner is the critical factor in determining beneficiary categories.11 OASDI is intended to insure covered wage earners and their families against the economic and social impact on the family normally entailed by loss of the wage earner's income due to retirement, disability, or death, by providing benefits to replace the lost wages. Cf. Jimenez v. Weinberger, 417 U. S. 628, 633-634 (1974). Thus, benefits are not paid, as under other welfare programs, simply to categories of the population at large who need economic assistance, but only to members of the family of the insured wage earner.12 Moreover, every family member other than a wife or widow is eligible for benefits only if a dependent of the covered wage earner.13 This ac[214]*214cords with the system’s general purpose; one who was not dependent to some degree on the covered wage earner suffers no economic loss when the wage earner leaves the work force. Thus the overall statutory scheme makes actual dependency the general basis of eligibility for OASDI benefits, and the statute, in omitting that requirement for wives and widows, reflects only a presumption that they are ordinarily dependent. At all events, nothing whatever suggests a reasoned congressional judgment that nondependent widows should receive benefits because they are more likely to be needy than nondependent widowers.
Finally, the legislative history of § 402 (f)(1)(D) refutes appellant’s contention. The old-age provisions of the original Social Security Act, 49 Stat. 622, provided pension benefits only to the wage earner himself, with a lump-sum payment to his estate under certain circumstances.14 Wives’ and widows’ benefits were first provided when coverage was extended to other family members in 1939. Social Security Act Amendments of 1939, 53 Stat. 1360, 1364—1366. The general purpose of the amendments was “to afford more adequate protection to the family as a unit.” H. R. Rep. No. 728, 76th Cong., 1st Sess., 7 (1939). (Emphasis supplied.) The House Ways and Means Committee criticized the old lump-sum payment because it “make[s] payments to the estate of a deceased person regardless of whether or not he leaves dependents.” Ibid. The Social Security Board, which had initiated the amendments in a report transmitted by the President to Congress, recommended the adop[215]*215tion of survivors’ benefits because “[t]he payment of monthly benefits to widows and orphans, who are the two chief classes of dependent survivors, would furnish more significant protection than does the payment of lump-sum benefits.” H. R. Doc. No. 110, 76th Cong., 1st Sess., 7 (1939).15 In addition to recommending survivors’ benefits, the Board suggested the extension of old-age pension benefits “for the aged dependent wife of the retired worker.” 16 Id., at 6. On the Senate floor, Senator Harrison, the principal proponent of the amendments, criticized the then-existing system of benefits because under it “no regard is had as to whether [the covered wage earner] has a dependent wife, or whether he dies leaving a child, widow, or parents.” 84 Cong. Rec. 8827 (1939). There is no indication whatever in any of the legislative history that Congress gave any attention to the specific case of nondependent widows, and found that they were in need of benefits despite their lack of dependency, in order to compensate them for disadvantages caused by sex discrimination. There is every indication that, as Wiesenfeld recognized, 420 U. S., at 644, “the framers of the Act legislated on the ‘then generally accepted presumption that a man is responsible for the support of his wife and children.’ D. Hoskins & L. Bixby, Women and [216]*216Social Security: Law and Policy in Five Countries, Social Security Administration Research Report No. 42, p. 77 (1973).” 17
Survivors’ and old-age benefits were not extended to husbands and widowers until 1950. 64 Stat. 483, 485. The legislative history of this provision also demonstrates that Congress did not create the disparity between nondependent widows and widowers with a compensatory purpose. The impetus for change came from the Advisory Council on Social Security, which recommended benefits for “the aged, dependent husband . . . [and] widower.” The purpose of this recommendation was “[t]o equalize the protection given to the dependents of women and men” because “[u]nder the present program, insured women lack some of the rights which insured men can acquire.” Advisory Council on Social Security, Recommendations for Social Security Legislation, S. Doc. No. 208, 80th Cong., 2d Sess., 38 (1949). (Emphasis supplied in part.) It is clear from the report that the Advisory Council assumed that the provision of benefits to dependent husbands and widowers was the equivalent of the provision of benefits to wives and widows under the previous statute, and not a lesser protection deliberately made because of lesser need. Although the original bill, H. R. 6000, that became the Social Security Act Amendments of 1950 did not contain a provision for husbands’ and widowers’ benefits, the Senate Finance Committee added it, because “the committee believes that protection given to dependents of women and men should be made more comparable.” S. Rep. No. 1669, 81st Cong., 2d Sess., 28 (1950). In 1950, as in 1939, there was simply no indication of an intention to create a differential treatment for the benefit of nondependent wives.
We conclude, therefore, that the differential treatment of nondependent widows and widowers results not, as appellant [217]*217asserts, from a deliberate congressional intention to remedy the arguably greater needs of the former, but rather from an intention to aid the dependent spouses of deceased wage earners, coupled with a presumption that wives are usually dependent. This presents precisely the situation faced in Frontiero and Wiesenfeld. The only conceivable justification for writing the presumption of wives’ dependency into the statute is the assumption, not verified by the Government in Frontiero, 411 U. S., at 689, or here, but based simply on “archaic and overbroad” generalizations, Schlesinger v. Ballard, 419 U. S., at 508, that it would save the Government time, money, and effort simply to pay benefits to all widows, rather than to require proof of dependency of both sexes.18 We held in Frontiero, and again in Wiesenfeld, and therefore hold again here, that such assumptions do not suffice to justify a gender-based discrimination in the distribution of employment-related benefits.
Affirmed.
