The ordinance here in question was before this Court in Kresge Co. v. Tomlinson, 275 N.C. 1, 165 S.E. 2d 236. We there held that legislative authority for its adoption was conferred upon the City of Raleigh by its charter and by G.S. 160-52 and G.S. 160-200(6), (7), and (10). We also there held, upon the authority of Charles Stores v. Tucker, 263 N.C. 710, 140 S.E. 2d 370, and Clark’s Charlotte, Inc. v. Hunter, 261 N.C. 222, 134 S.E. 2d 364, that the provisions of the ordinance are not unreasonable, arbitrary or discriminatory as applied to the plaintiffs in that action, they being operators of depart*665ment stores in the city selling various articles of merchandise. In the Kresge case, the principal ground of attack upon the ordinance was that it violated the First Amendment to the Constitution of the United States. This Court rejected that contention, citing as authority McGowan v. Maryland, 366 U.S. 420, 81 S. Ct. 1101, 6 L. ed. 2d 393, and Two Guys v. McGinley, 366 U.S. 582, 81 S. Ct. 1135, 6 L. ed. 2d 551, reh. den. 368 U.S. 869, 82 S. Ct. 21, 7 L. ed. 2d 69.
[1] The ordinance prohibits the sale or offering for sale within the city on Sunday of “any goods, wares or merchandise,” except as expressly permitted by the ordinance. It does not refer to or apply to sales of real property. The plaintiff in this action does not contend that the ordinance discriminates unconstitutionally against it by reason of the provisions authorizing sales on Sunday of certain types of “goods, wares and merchandise” other than mobile homes. Its contention is that by an ordinance, otherwise valid, a city may not prohibit the selling or offering for sale on Sunday of mobile homes, by a general prohibition of the selling or offering for sale of “goods, wares and merchandise,” if the city does not also prohibit the selling or offering for sale on Sunday of “conventional homes”; that is, homes so affixed to land as to become real property. This is the only question presented by this appeal which has not previously been determined by this Court.
It is well established that the provisions of Article I, § 17, and Article I, § 26, of the Constitution of North Carolina, do not deprive the Legislature of authority to prohibit by a statute, otherwise valid, the carrying on of and engaging in, on Sunday, any and all labor and the operation of industrial and commercial pursuits, except for works of necessity and acts which, themselves, are in exercise of the constitutional right to worship. Kresge Co. v. Tomlinson, supra; Charles Stores v. Tucker, supra; Clark’s Charlotte, Inc. v. Hunter, supra; State v. McGee, 237 N.C. 633, 75 S.E. 2d 783; State v. Trantham, 230 N.C. 641, 55 S.E. 2d 198. The Legislature may delegate this power to municipalities. State v. McGee, supra.
. It is equally well settled that such legislation is within the police power of the State and, nothing else appearing, is not a violation of the Fourteenth Amendment to the Constitution of the United States or of the First Amendment thereto, now deemed incorporated into the Fourteenth. McGowan v. Maryland, supra.
Human experience has demonstrated that there is a close relationship between health, morality and general welfare on the one hand and the regular observance of one day in seven as a day of rest and recreation on the other. It has also demonstrated the practical *666necessity of legislation, designating a specific day in the week for that purpose and prohibiting activities on that day which interfere substantially with the accomplishment of such purpose. It would not be practicable for the State, or the municipality, simply to require for all of its citizens one day of rest in seven, leaving it to each individual to choose the day most convenient for him. See McGowan v. Maryland, supra. As the Supreme Court of the United States said in the McGowan case, supra, at page 460:
“[T]he State’s purpose is not merely to provide a one-day-in-seven work stoppage. In addition to this, the State seeks to set one day apart from all others as a day of rest, repose, recreation and tranquility —• a day which all members of the family and community have the opportunity to spend and enjoy together, a day on which there exists relative quiet and disassociation from the every day intensity of commercial activities, a day on which people may visit friends and relatives who are not available during working days.”
[2, 3] The choice of the day of the week to be observed as the day of rest and relaxation is for the Legislature. Obviously, it cannot choose a day which accords with the wishes and religious convictions of all of the people. In making its choice, the Legislature may take into account the fact that Sunday is the day of the week which a great proportion of the people would observe as a day of rest apart from the statute, whether this be due to the religious conviction of such persons or to their traditions and customs. The choice of Sunday by the Legislature does not render the statute unconstitutional, as a law establishing a religion or interfering with freedom of worship, merely because other persons are required by their religious convictions to rest from their labors on a different day of the week, or, having no religious convictions, consider Sunday as an exceptionally promising day for business. McGowan v. Maryland, supra; Henninglon v. Georgia, 163 U.S. 299, 16 S. Ct. 1086, 41 L. ed. 166; State v. McGee, supra. Laws against murder, larceny, adultery and perjury are not rendered invalid by reason of the fact that these acts are also forbidden by the Ten Commandments. Similarly, a law requiring the observance of Sunday as a day of rest and relaxation does not cease to be a reasonable exercise of the police power of the State, merely because it is in harmony with the religious beliefs of most Christian denominations.
[4, 5] The validity of a specific statute or ordinance depends, however, upon its reasonable relation to the accomplishment of the State’s legitimate objective, which, in this instance, is the promo*667tion of the public health, safety, morals and welfare by the establishment of a day of rest and relaxation. Legislation for this purpose, like other legislation, may not discriminate arbitrarily either as between persons, or groups of persons, or as between activities-which are prohibited and those which are permitted. State v. Smith, 265 N.C. 173, 143 S.E. 2d 293.
[5] On the other hand, neither the State nor the Federal Constitution requires that a statute or ordinance, enacted for this purpose, be held invalid unless it prohibits every activity which could be brought within its scope. The general prohibition is not invalidated by excepting therefrom activities which may reasonably be thought to contribute to .the rest, relaxation or other need of a segment of the public to a degree sufficient to outweigh the interference resulting therefrom to the rest and relaxation of the remainder. The weighing of such benefits and detriments is for the legislative body in the first instance. Its determination will not be disturbed by the courts unless clearly unreasonable.
In State v. Trantham, supra, this Court, speaking through Barn-hill, J., later C.J., with reference to an ordinance prohibiting secular pursuits on Sunday, said:
“Legislative bodies may distinguish, select, and classify objects of legislation. It suffices if the classification is practical. (Citations omitted.) They may prescribe different regulations for different classes, and discrimination as between classes is not such as to invalidate the legislative enactment.”
To the same effect, see: Clark’s Charlotte, Inc. v. Hunter, supra; State v. Towery, 239 N.C. 274, 79 S.E. 2d 513; State v. McGee, supra.
With reference to the Equal Protection Clause of the Fourteenth Amendment to the Federal Constitution, the Supreme Court of the United States, speaking through Stone, J., later C.J., said in Silver v. Silver, 280 U.S. 117, 50 S. Ct. 57, 74 L. ed. 221, 65 A.L.R. 939:
“[T]here is no constitutional requirement that a regulation, in other respects permissible, must reach every class to which it might be applied — that the legislature must be held rigidly to the choice of regulating all or none. * * * It is enough that the present statutes strike at the evil where it is felt and reaches the class of cases where it most frequently occurs.”
Again, in Dominion Hotel v. Arizona, 249 U.S. 265, 268, 39 S. Ct. 273, 63 L. ed. 597, the Court, speaking through Holmes, J., said:
“The Fourteenth Amendment is not a pedagogical requirement of the impractical. The equal protection of the law does *668not mean that all occupations that are called by the same names must be treated in the same way. The power of the State 'may be determined by degrees of evil or exercised in cases where detriment is specially experienced.’ Armour & Co. v. North Dakota, 240 U.S. 510, 517. It may do what it can to prevent what is deemed an evil and stop short of those cases in which the harm to the few concerned is thought less important than the harm to the public that would ensue if the rule laid down were made mathematically exact. The only question is whether we can say on our judicial knowledge that the Legislature of Arizona could not have had any reasonable ground for believing that there were public considerations for the distinction made by the present law.”
[1] The contention of the plaintiff is that an arbitrary discrimination has been made by the city in that the ordinance prohibits the sale on Sunday of mobile homes, along with ether “goods, wares and merchandise,” but does not prohibit the sale on Sunday of “conventional homes,” so attached to land as to become real property. Obviously, there are differences between the two types of property, and between the businesses of selling the two types of property, which will make reasonable and, therefore, constitutionally valid, some differences between legislation relating to the one and legislation relating to the other. The question which we are required by this appeal to determine is whether it may reasonably be thought that there is a difference between the two types of business, or between the customary procedures in conducting them, which makes reasonable the prohibition of the sale of one type of property on Sunday without prohibiting the sale of the other type of property on Sunday. The objective of the ordinance being the establishment of Sunday as a day of general rest and relaxation, the difference in treatment of the two types of business must be supported by a reasonable basis for the conclusion that one, substantially more than the other, will interfere with such use and enjoyment of the day. McGowan v. Maryland, supra; Clark’s Charlotte, Inc. v. Hunter, supra; State v. Towery, supra; 50 Am. Jur., Sundays and Holidays, § 11.
[6] The legislative body has a wide discretion in determining which activities do and which activities do not interfere with the observance of Sunday as a day of general rest and relaxation sufficiently to justify the prohibition of those activities on that day. The burden rests upon the person complaining to establish the absence of a reasonable basis for such determination. In Metropolitan Casualty Insurance Co. v. Brownell, 294 U.S. 580, 584, 55 S. Ct. 538, 79 L. ed. 1070, the-Court, speaking-through Stone, J., later C.J., said:
*669“It is a salutary principle of judicial decision, long emphasized and followed by this Court, that the burden of establishing the unconstitutionality of a statute rests upon him who assails it, and that courts may not declare a legislative discrimination invalid unless, viewed in the light of facts made known or generally assumed, it is of such a character as to preclude the assumption that the classification rests upon some rational basis within the knowledge and experience of the legislators. A statutory discrimination will not be set aside as the denial of equal protection of the laws if any state of facts reasonably may be conceived to justify it.” (Emphasis added.)
In Lindsley v. Natural Carbonic Gas Co., 220 U.S. 61, 78-79 31 S. Ct. 337, 55 L. ed. 369, the- Court, speaking through VanDevanter, J., said:
“1. The equal protection clause of the Fourteenth Amendment does not take from the State the power to classify in the adoption of police laws, but admits of the exercise of a wide scope of discretion in that regard, and avoids what is done only when it is without any reasonable basis and therefore purely arbitrary. 2. A classification having some reasonable basis does not offend against that'clause merely because it is not made with mathematical nicety or because in practice it results in -some inequality. 3. When the classification in such a law is called in question, if any state of facts reasonably can be conceived that would sustain it, the existence of that state of facts at the time the law was enacted must be assumed. 4. One who assails the classification in such a law must carry the burden of showing that it does not rest upon any reasonable basis, but is essentially arbitrary.” (Emphasis added.)
In Patsone v. Commonwealth of Pennsylvania, 232 U.S. 138, 144, 34 S. Ct. 281, 58 L. ed. 539, the Court, speaking through Holmes, J., said:
“[W]e start with the general consideration that a State may classify with reference to the evil to be prevented, and that if the class discriminated against is or reasonably might be considered to define those from whom the evil mainly is to be feared, it properly may be picked out. A lack of abstract symmetry does not matter. The question is a practical one dependent upon experience. * * * It is not enough to invalidate the law that others may do the same thing and go unpunished, if, as a matter of fact, it is found that the danger is characteristic of the class' named. (Citation, omitted.) The State ‘may direct its law *670against what it deems the evil as it actually exists without covering the whole field of possible abuses.’ Central Lumber Co. v. South Dakota, 226 U.S. 167, 160.” (Emphasis added.)
More recently, and with specific reference to laws designed to establish Sunday as a day of rest and relaxation, the Supreme Court of the United States said, in McGowan v. Maryland, supra, at pages 425-426:
“The constitutional safeguard is offended only if the classification rests on grounds wholly irrelevant to the achievement of the State’s objective. State Legislatures are presumed to have acted within their constitutional power despite the fact that, in practice, their laws result in some inequality. A statutory discrimination will not be set aside if any state of fact reasonably may be conceived to justify it.
* * *
“The record is barren of any indication that this apparently reasonable basis does not exist, that the statutory distinctions are invidious, that local tradition and custom might not rationally call for this legislative treatment.”
The same assumption in favor of the reasonableness of the legislative classification applies with reference to the requirements of Article I, § 17, of the Constitution of North Carolina. See Clark’s Charlotte, Inc. v. Hunter, supra. See also Annot., 46 A.L.R. 290, 291.
The only case which has come to our attention in which the contention was made that a law forbidding the sale of personal property on Sunday was unconstitutional because it permitted the sale of real estate is Motor Car Dealers’ Ass’n. v. Fred S. Haines Co., 128 Wash. 267, 222 P. 611, 36 A.L.R. 493. The Supreme Court of Washington disposed of the contention summarily in favor of the validity of the statute.
[7] Since this appeal comes before us upon a demurrer to the complaint, the facts must be taken as stated therein. The demurrer does not admit the pleader’s conclusions of law. When so considered, “the record is barren” of any showing that there is no reasonable basis for the classification made by this ordinance.
[1] The distinction drawn by this ordinance between the two types of business is not necessarily permissible because one sells personal property and the other sells real property. Conversely, the difference in the treatment of the two is not necessarily impermissible because in each instance the thing sold is designed for use as a residence and to some buyers both types of home are attractive. The determina*671tive question is whether the legislative body could reasonably conclude that the customary practices and procedures followed in selling mobile homes, not yet located where they are to be used as homes, are substantially more likely to impair Sunday as a day of general rest and relaxation than are the customary practices and procedures followed in selling homes already built upon the lots on which their owners will live in them. It is not determinative that the complainant shows, or the court takes notice of, the fact that, in particular instances, the offering for sale of a home already affixed to the land at the site of its intended use is accompanied by as much traffic congestion, noise and disturbance of the neighborhood as exist in particular instances of the offering for sale of a mobile home.
Without attempting to enumerate all the differences between the two types of business, we are mindful that in the mobile home business, many units are exhibited and offered for sale simultaneously on the same lot and, as sold, are promptly removed and replaced by other units, so that the sale at this location goes on Sunday after Sunday, resulting in more or less continuous traffic movement, congestion and noise in the vicinity. The proprietor of the business, naturally, uses all reasonable means to maintain this condition Sunday after Sunday. In the case of the conventional homes, a sale once made is not soon repeated, and even in the case of an effort to sell many houses in a new development, the area affected is larger, the congestion of trafile less and the seller seeks to terminate the selling process at that location as quickly as possible. One of the principal attractions to a purchaser of a home is a quiet, restful neighborhood. This may reasonably be supposed to be borne in mind by the seller of a conventional home in his choice of selling procedures. The lack of restful quiet at the mobile home sales lot is not likely to chill the interest of the prospective buyer. In the absence of a showing by the complainant that these or other reasonable bases for the legislative conclusion do not exist in the City of Raleigh, we cannot hold it arbitrary.
Affirmed.
Bobbitt, C.J. and Sharp, J., concur in result.
