The question presented by this case is whether the provision of a New Orleans ordinance, as amended in 1972, that excepts from the ordinance’s prohibition against vendors’ selling of foodstuffs from pushcarts in the Vieux Carre, or French Quarter, “vendors who have continuously operated the same business within the Vieux Carre ... for eight or more years prior to January 1, 1972 . . .” denied appellee vendor equal protection of the laws in violation of the Fourteenth Amendment. 1
Appellee operates a vending business from pushcarts throughout New Orleans but had carried on that business in the Vieux Carre for only two years when the ordinance was amended in 1972 and barred her from
*299
continuing operations there.

She had previously filed an action in the District Court for the Eastern District of Louisiana attacking the validity of the former version of the ordinance,
3
and amended her complaint to challenge the application of the ordinance’s “grandfather clause” — the eight-years-or-more provision — as a denial of equal protection. She prayed for an injunction and declaratory judgment. On cross-motions for summary judgment, the District Court, without opinion, granted appellant city’s motion. The Court of Appeals for the Fifth Circuit reversed.
The Yieux Carre of the city of New Orleans is the heart of that city’s considerable tourist industry and an integral component of the city’s economy. 4 The sector plays a special role in the city’s life, and pursuant to the Louisiana State Constitution, c. 8 of Art. V of the city’s Home Rule Charter grants the New Orleans City Council power to enact ordinances designed to preserve its distinctive charm, character, and economic vitality.
Chapter 46 of the Code of the City of New Orleans sets up a comprehensive scheme of permits for the conduct of various businesses in the city. In 1972, the Code was amended to restrict the validity of many of these per
*300
mits to points outside the Vieux Carre. However, even as to those occupations — including all pushcart food vendors — which were to be banned from the Vieux Carre during seasons other than Mardi Gras, the City Council made the “grandfather provision” exception. Two pushcart food vendors — one engaged in the sale of hot dogs and the other an ice cream vendor — had operated in the Vieux Carre for 20 or more years and therefore qualified under the “grandfather clause” and continued to operate there. The Court of Appeals recognized the “City Council’s legitimate authority generally to regulate business conducted on the public streets and sidewalks of the Vieux Carre in order to preserve the appearance and custom valued by the Quarter’s residents and attractive to tourists,”

The question of this Court’s jurisdiction to hear the appeal need detain us only briefly. Title 28 XJ. S. C. § 1254 (2) grants jurisdiction to review decisions of the courts of appeals
“[b]y appeal by a party relying on a State statute held by a court of appeals to be invalid as repugnant to the Constitution, treaties or laws of the United States . . . .”
A municipal ordinance is a “State statute” for purposes of this provision. See
Doran
v.
Salem Inn, Inc.,
However, it is argued that the Court of Appeals’ decision is not “final” under the doctrine enunciated in
Slaker
v.
O’Connor,
The unconstitutionality of the ordinance, in its application to appellee, has been definitely and finally adjudicated by the Court of Appeals, and only a state-law question remains to be decided on remand — whether the statute will be totally invalidated or whether only its “grandfather provision” will be struck down. There is no federal, much less constitutional, question which is yet to be resolved below, and the policy underlying § 1254 (2) — ensuring that state laws are not erroneously invalidated — will in no way be served by further delay in adjudicating the constitutional issue presented. Moreover, since the outcome of the severability question will not moot a difficult constitutional issue in this case, the policy of avoiding needless constitutional decisions would not be furthered by staying our hand. Furthermore, to the extent any “finality” requirement in the context of § 1254 (2) might be premised on the policies of avoiding piecemeal appeals or the rendering of advisory opinions, neither difficulty is likely to eventuate in this case; even if we were to uphold the Court of Appeals’ remand for a determination of the severability of the “grandfather provision” under state law, the ruling on remand is not one which would be subject to further review in this Court. On the other hand, a decision by this Court rejecting the constitutional challenge to the statute will obviate the need for further proceedings and bring to a halt the continued disruption of the city’s internal economic affairs. Cf. generally, e. g., Cox Broadcasting Corp. v. Cohn, 420 U. S. 469, 476-478, 480, 485-486 (1975). We accordingly hold that this appeal is prop *303 erly before us under 28 U. S. C. § 1254 (2). We therefore turn to the merits.

The record makes abundantly clear that the amended ordinance, including the “grandfather provision/’ is solely an economic regulation aimed at enhancing the vital role of the French Quarter’s tourist-oriented charm in the economy of New Orleans.
When local economic regulation is challenged solely as violating the Equal Protection Clause, this Court consistently defers to legislative determinations as to the desirability of particular statutory discriminations. See,
e. g., Lehnhausen
v.
Lake Shore Auto Parts Co.,
The Court of Appeals held in this case, however, that the “grandfather provision” failed even the rationality test. We disagree. The city’s classification rationally furthers the purpose which the Court of Appeals recognized the city had identified as its objective in enacting the provision, that is, as a means “to preserve the appearance and custom valued by the Quarter’s residents and attractive to tourists.”
It is suggested that the “grandfather provision,” allowing the continued operation of some vendors was a, totally arbitrary and irrational method of achieving the city’s purpose. But rather than proceeding by the immediate and absolute abolition of all pushcart food vendors, the city could rationally choose initially to eliminate vendors of more recent vintage. This gradual approach to the problem is not constitutionally impermissible. The governing constitutional principle was stated in Katzenbach v. Morgan, supra, at 657:
“[W]e are guided by the familiar principles that a 'statute is not invalid under the Constitution because it might have gone farther than it did,’ Roschen v. Ward,279 U. S. 337 , 339, that a legislature need not 'strike at all evils at the same time,’ Semler v. Dental Examiners,294 U. S. 608 , 610, and that 'reform may take one step at a time, addressing itself to the phase of the problem which seems most acute to the legislative mind,’ Williamson v. Lee Optical Co.,348 U. S. 483 , 489.”
The city could reasonably decide that newer businesses were less likely to have built up substantial reliance interests in continued operation in the Vieux Carre and that the two vendors who qualified under the “grandfather clause” — both of whom had operated in the area for over 20 years rather than only eight — had themselves become part of the distinctive character and charm that distinguishes the Vieux Carre. We cannot say that these judgments so lack rationality that they constitute a constitutionally impermissible denial of equal protection.

Nevertheless, relying on
Morey
v.
Doud,
The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
The pertinent provision of the New Orleans ordinance, c. 46, §§ 1 and 1.1 of the Code of the City of New Orleans, as amended August 31, 1972, provides:
“Vendors who have continuously operated the same business within the Vieux Carre under the authority of this Chapter for eight or more years prior to January 1, 1972 may obtain a valid permit to operate such business within the Vieux Carre.”
Most of appellee’s sales, particularly during the summer months, were made in the Yieux Carre.
Jurisdiction was invoked pursuant to 28 U. S. C. §§ 1331, 1343 (3), (4), and 2201-2202. The equal protection violation was alleged to constitute a violation of 42 U. S. C. §§ 1983, 1985.

Ferguson
presented an analogous situation. There, a Kansas statute excepted lawyers from the prohibition of a statute making it a misdemeanor for any person to engage in the business of debt adjusting. We held that the exception of lawyers was not a denial of equal protection, stating,
“Nor is the statute’s exception of lawyers a denial of equal protection of the laws to nonlawyers. Statutes create many classifications which do not deny equal protection; it is only 'invidious discrimination’ which offends the Constitution. ... If the State of Kansas wants to limit debt adjusting to lawyers, the Equal Protection Clause does not forbid it” (footnote omitted).
We emphasize again that these principles, of course, govern only when no constitutional provision other than the Equal Protection Clause itself is apposite. Very different principles govern even economic regulation when constitutional provisions such as the Commerce Clause are implicated, or when local regulation is challenged under the Supremacy Clause as inconsistent with relevant federal laws or treaties.
