Prostitution is illegal in the vast majority of the United States as a result of state laws rather than federal laws. It is, however, legal in some rural counties within the state of Nevada. Additionally, it is decriminalized to sell sex in the state of Maine, but illegal to buy sex. Prostitution nevertheless occurs elsewhere in the country.

The regulation of prostitution in the country is not among the enumerated powers of the federal government. It is therefore exclusively the domain of the states to permit, prohibit, or otherwise regulate commercial sex under the Tenth Amendment to the United States Constitution, except insofar as Congress may regulate it as part of interstate commerce with laws such as the Mann Act. In most states, prostitution is considered a misdemeanor in the category of public order crime–crime that disrupts the order of a community. Prostitution was once considered a vagrancy crime.

Currently, Nevada is the only U.S. state to allow legal prostitution – in the form of regulated brothels – the terms of which are stipulated in the Nevada Revised Statutes.

There are ten counties that theoretically allow brothel prostitution, but four of these counties (Churchill, Esmeralda, Humboldt, and Mineral) currently have no active brothels. Only these six counties currently contain active legal brothels: Elko, Lyon, Nye, White Pine, Lander & Storey.^[1]

All forms of prostitution are illegal in these seven counties: Clark (which contains the Las Vegas–Paradise metropolitan area), Washoe (which contains Reno), Carson City, Douglas, Eureka, Lincoln & Pershing. Street prostitution, "pandering", and living off of the proceeds of a prostitute remain illegal under Nevada law, as is the case elsewhere in the country.

According to the National Institute of Justice, a study conducted in 2008 alleged that approximately 15-20 percent of men in the country have engaged in commercial sex.^[2]

As with other countries, prostitution in the U.S. can be divided into three broad categories: street prostitution, brothel prostitution, and escort prostitution.

Some of the women in the American Revolution who followed the Continental Army served the soldiers and officers as sexual partners. Prostitutes were a worrisome presence to army leadership, particularly because of the possible spread of venereal diseases (in modern terms, sexually transmitted infection or STI).

In the 19th century, parlor house brothels catered to upper class clientele, while bawdy houses catered to the lower class. At concert saloons, men could eat, listen to music, watch a fight, or pay women for sex. Over 200 brothels existed in lower Manhattan. Prostitution was illegal under the vagrancy laws, but was not well-enforced by police and city officials, who were bribed by brothel owners and madams. Attempts to regulate prostitution were struck down on the grounds that regulation would be counter to the public good.

While official acts of regulation were being struck down, there were those of a more religious perspective who took this act of reforming prostitution into their own hands. The Magdalen Society was an organization in the 1800s that had sought to take prostitutes of the streets and turn them into respectable women. Motivated by the concern that Philadelphia was falling into social disorder, the society founded an asylum to take women off of the streets.^[3] 138 women sought refuge here in the years between 1807 and 1820, and were placed with religious families who taught them how to read convert them into a respectable woman. Most of the women who entered the asylum only stayed for two and a half months, using the open doors as a temporary place to live off the street.^[3] The biggest success story of the society was that of Elizabeth Ogden, a woman who was deemed reformed and opened a school for children.^[4]

The gold rush profits of the 1840s to 1900 attracted gambling, crime, saloons, and prostitution to the mining towns of the wild west. A brothel-keeper, Julia Bulette, who was active in the mining town of Virginia City, Nevada, was murdered in 1867. Thirty years before, in 1836, the New York City courtesan Helen Jewett was murdered by one of her customers, gaining prostitution considerable attention. The Lorette Ordinance of 1857 prohibited prostitution on the first floor of buildings in New Orleans.^[5] Nevertheless, prostitution continued to grow rapidly in the U.S., becoming a $6.3 million business in 1858, more than the shipping and brewing industries combined.

Some army officers, however, encouraged the presence of prostitutes during the Civil War to keep troop morale high. On August 20, 1863, the U.S. military commander Brig. General Robert S. Granger legalized prostitution in Nashville, Tennessee, in order to curb venereal disease among Union soldiers. The move was successful and venereal disease rates fell from forty percent to just four percent due to a stringent program of health checks which required all prostitutes to register and be examined by a board certified physician every two weeks for which they were charged five dollars registration fee plus 50 cents each time.^[6]

By the U.S. Civil War, Washington's Pennsylvania Avenue had become a disreputable slum known as Murder Bay, home to an extensive criminal underclass and numerous brothels. So many prostitutes took up residence there to serve the needs of General Joseph Hooker's Army of the Potomac that the area became known as "Hooker's Division." (It is from this period that the slang term "hooker" originates.) Two blocks between Pennsylvania and Missouri Avenues became home to such expensive brothels that it was known as "Marble Alley."^[7]

In 1873, Anthony Comstock created the New York Society for the Suppression of Vice, an institution dedicated to supervising the morality of the public. Comstock successfully influenced the United States Congress to pass the Comstock Law, which made illegal the delivery or transport of "obscene, lewd, or lascivious" material and birth control information. In 1875, Congress passed the Page Act of 1875 that made it illegal to transport women into the nation to be used as prostitutes.^[8]

In 1881, the Bird Cage Theatre opened in Tombstone, Arizona. It included a brothel in the basement and 14 cribs suspended from the ceiling, called cages. Local men such as Doc Holliday, Bat Masterson, Diamond Jim Brady, and George Hearst frequented the establishment.^{[citation needed]}

In the late 19th century, newspapers reported that 65,000 white slaves existed. Around 1890, the term "red-light district" was first recorded in the United States. From 1890 to 1982, the Dumas Brothel in Montana was America's longest-running house of prostitution.

New Orleans city alderman Sidney Story wrote an ordinance in 1897 to regulate and limit prostitution to one small area of the city, "The District", where all prostitutes in New Orleans must live and work. The District, which was nicknamed Storyville, became the best known area for prostitution in the nation. Storyville at its peak had some 1,500 prostitutes and 200 brothels.

Japanese girls and women worked as Karayuki-san prostitutes in the west coast of the United States and provided sexual services to Chinese men, white men and Japanese men in America in the 19th and early 20th centuries since most Chinese immigrants at the time were male so the Chinese men were forced to use Japanese prostitutes for relations with women.^[9][10] Japanese prostitutes worked in the American west and also as barmaids.^[11] The Issei Japanese American Bunshiro Tazuma said "At the age of 18… I started… work as a dishwasher at a hotel in Spokane. Later I became a [railroad?] cook and went to North Dakota, South Dakota, Idaho, Oregon, Washington, and even as far as to Minnesota and Alaska… To my surprise I found at least two to six Japanese prostitutes in every town where I went between Seattle and St. Paul, a range of two thousand miles. Even when I went to Alaska to… a salmon cannery in 1908, I was surprised to see from two to five or six in such towns as Ketchikan, Juneau, Wrangell, Sitka, and Skagway.”^[12]

In 1908, the government founded the Bureau of Investigation (BOI, from 1935, the FBI) to investigate "white slavery" by interviewing brothel employees to discover if they had been kidnapped. Out of 1,106 prostitutes interviewed in one city, six said they were victims of white slavery. The White-Slave Traffic Act (Mann Act) of 1910 prohibited so-called white slavery. It also banned the interstate transportation of women for "immoral purposes". Its primary stated intent was to address prostitution and perceived immorality. The Supreme Court later included consensual debauchery, adultery, and polygamy under "immoral purposes". Prior to World War I, there were few laws criminalizing prostitutes or the act of prostitution.^[13]

During World War I, the U.S. government developed a public health program called the American Plan which authorized the military to arrest any woman within five miles of a military cantonment. If found infected, a woman could be sentenced to a hospital or a "farm colony" until cured. By the end of the war 15,520 prostitutes had been imprisoned, the majority never being medically hospitalized.^[14]

In 1918, the Chamberlain–Kahn Act which implemented the American Plan,^[15] gave the government the power to quarantine any woman suspected of having venereal disease. A medical examination was required, and if it revealed to be VD, this discovery could constitute proof of prostitution. The purpose of this law was to prevent the spread of venereal diseases among U.S. soldiers.^[16] During World War I, Storyville, a district in New Orleans where prostitution was permitted, was shut down to prevent VD transmission to soldiers in nearby army and navy camps.^[17]

On January 25, 1917, an anti-prostitution drive in San Francisco attracted huge crowds to public meetings. At one meeting attended by 7,000 people, 20,000 were kept out for lack of room. In a conference with Reverend Paul Smith, an outspoken foe of prostitution, 300 prostitutes made a plea for toleration, explaining they had been forced into the practice by poverty. When Smith asked if they would take other work at $8 to $10 a week, the ladies laughed derisively, which lost them public sympathy. The police closed about 200 houses of prostitution shortly thereafter.^[18]

The National Venereal Disease Control Act, which became effective July 1, 1938, authorized the appropriation of federal funds to assist the states in combating venereal diseases. Appropriations under this act were doubled after the United States entered the war.

The May Act, which became law in June 1941, intended to prevent prostitution on restricted zones around military bases. It was invoked chiefly during wartime. See World War II U.S. Military Sex Education.

Mortensen vs. United States, in 1944, ruled that prostitutes could travel across state lines, if the purpose of travel was not for prostitution.^[19]

Conditions for sex trade workers changed considerably in the 1960s. The combined oral contraceptive pill was first approved in 1960 for contraceptive use in the United States. "The Pill" helped prostitutes prevent pregnancy.

In 1967, New York City eliminated license requirements for massage parlors. Many massage parlors became brothels.^[20] In 1970, Nevada began regulation of houses of prostitution. In 1971, the Mustang Ranch became Nevada's first licensed brothel, eventually leading to the legalization of brothel prostitution in 10 of 17 counties within the state. In time, Mustang Ranch became Nevada's largest brothel, with more revenue than all other legal Nevada brothels combined. By World War II, prostitutes had increasingly gone underground as call girls.

In 1971, the New York madam Xaviera Hollander wrote The Happy Hooker: My Own Story, a book that was notable for its frankness at the time, and considered a landmark of positive writing about sex. An early forerunner (1920s-1930s) of Xaviera Hollander's, both as a madam and author, was Polly Adler, whose bestselling book, A House Is Not a Home, was eventually adapted as a film also entitled A House is Not a Home. Carol Leigh, a prostitute's rights activist known as the "Scarlot Harlot," coined the term "Sex worker" in 1978. That same year, the Broadway musical The Best Little Whorehouse in Texas opened. It was based on the real-life Texas Chicken Ranch brothel. The play was the basis for the 1982 film starring Dolly Parton and Burt Reynolds.

COYOTE, formed in 1973, was the first sex workers' rights group in the country. Other sex workers movements later formed, such as FLOP, HIRE, and PUMA.^[21]

In 1997, "Hollywood Madam" Heidi Fleiss was convicted in connection with her prostitution ring with charges including pandering and tax evasion. Her ring had numerous wealthy clients. Her original three-year sentence prompted widespread outrage at her harsh punishment, while her customers had not been punished. Earlier, in the 1980s, a member of Philadelphia's social elite, Sydney Biddle Barrows was revealed as a madam in New York City. She became known as the Mayflower Madam.

In 1990, U.S. Representative Barney Frank (D-MA) admitted to paying for sex in 1989. The House of Representatives voted to reprimand him.^[22]

Ted Haggard, former leader of the National Association of Evangelicals, resigned in 2006 after he was accused of soliciting homosexual sex and methamphetamine.^[23]

Randall L. Tobias, former Director of U.S. Foreign Assistance and U.S. Agency for International Development Administrator, resigned in 2007 after being accused of patronizing a Washington escort service.^[24]

In 2007, U.S. Senator from Louisiana David Vitter acknowledged past transgressions after his name was listed as a client of "D.C. Madam" Deborah Jeane Palfrey's prostitution service in Washington.^[25]

Eliot Spitzer resigned as governor of New York in 2008 amid threats of impeachment after news reports alleged he was a client of an international prostitution ring.^[26]

In 2009, Rhode Island signed a bill into law making prostitution a misdemeanor. Prior to this law, between 1980 and 2009, Rhode Island was the only U.S. state where prostitution was decriminalized, as long as it was done indoors.^[27] (See Prostitution in Rhode Island).

In 2014, due to the stagnant economy in Puerto Rico, the government considered legalizing prostitution.^[28][29] In 2018, economist Robin Hanson suggested that the legalization of prostitution may solve the problem of inceldom, an ideology responsible for numerous outbreaks of violence and mass killings throughout the United States.^[30][31][32]

On April 11, 2018, the United States Congress passed the Stop Enabling Sex Traffickers Act, commonly known as FOSTA-SESTA, which imposed severe penalties on online platforms that facilitated illicit sex work. The effectiveness of the bill has come into question as it has purportedly endangered sex workers and has been ineffective in catching and stopping sex traffickers.^[33] Prior to the Act being signed, the Department of Justice seized the website Backpage and charged its founders with money laundering and promotion of prostitution, contributing to major destabilization in the lives of people who trade sex.

On June 16, 2021, Texas governor Greg Abbott signed HB1540, a law which makes paying for sex in the state of Texas a state jail felony punishable up to two years in prison for a first-time offense, in addition to enhanced penalties for recruitment from child care or treatment facilities. Texas is the first state in the United States to make the buying of sex a felony. This law represents a shift from the traditional approach, targeting buyers of sexual services rather than sellers. State representative Senfronia Thompson (D-Houston), the author of the bill, said "We know the demand is the driving force behind human sex trafficking. If we can curb or stamp out the demand end of it, then we can save the lives of numerous persons." The law went into effect on September 1, 2021.^[34]

On June 26, 2023, the state of Maine enacted a law that would partially decriminalize the act of prostitution, following the Nordic model; it is currently in effect.^[35]

The prostitution of children in the United States is a serious concern.^[36][37] More than 100,000 children are reportedly forced into prostitution in the United States every year.^[38][39]

Jessica Lustig has argued that American anti-prostitution laws tend to disadvantage girls who are American citizens, while federal laws tend to prioritize the well-being of foreign-born girls. She points out that a 14 year old Chinese girl trafficked into the country for use in prostitution would be viewed as a victim and offered a temporary visa, protection, and support services. Yet, a 14 year old American girl arrested for prostitution would be seen as a criminal and may end up in a juvenile facility.^[40]

Although informal, red light districts can be found in some areas of the country. Since prostitution is illegal everywhere except for a few counties in Nevada, there are no formal brothels in most parts of the country, but massage parlors offering prostitution may be found along with street prostitution. Typically, these areas will also have other adult-oriented businesses, often due to zoning, such as strip clubs, sex shops, adult movie theaters, adult video arcades, peep shows, sex shows, and sex clubs.

Street prostitution is illegal throughout the United States. Street prostitution tends to be clustered in certain areas known for solicitation. For instance, statistics on official arrests from the Chicago Police Department from August 19, 2005, to May 1, 2007, suggest that prostitution activity is highly concentrated: nearly half of all prostitution arrests occur in a tiny one-third of one percent of all blocks in the entire city of Chicago.^[41] Street prostitutes who exchange sex for drugs are sometimes known as "strawberries".^[42]

A study of violence against women engaged in street prostitution by clinical psychologist and anti-prostitution activist Melissa Farley found that 68% reported having been raped and 82% reported having been physically assaulted.^[43]

A variation of street prostitution is that which occurs at truck stops along Interstate highways in rural areas. Called "lot lizards", these prostitutes solicit at truck stop parking lots and may use CB radios to communicate.

In today's society there is a hierarchy amongst prostitutes and an even greater distinction between indoor workers and outdoor workers. The indoor prostitutes occupy the top tier to include independent call girls, and workers in brothels and massage parlors. The outdoor street walkers occupy the lowest level and are more likely to experience abuse.^[44] 250 prostitutes, including 150 outdoor workers and 125 indoor workers, were interviewed for a study about victimization. Weitzer, R (2005) noted that indoor workers experienced less harm compared to outdoor workers:

Type of abuse	Outdoor workers	Indoor workers
Robbed	37%	10%
Beaten	27%	1%
Slapped, punched, kicked	47%	14%
Raped	22%	2%
Kidnapped	20%	2%

The outdoor prostitutes or streetwalkers are the most recognized sex workers, but they make up a small number of workers. Cunningham & Kendall (2011) report that only 20% of prostitutes work on the streets. The indoor workers have more freedom to choose their clients and set boundaries that contribute to their safety.^[45]

In spite of its illegality, escort prostitution exists throughout the United States from both independent prostitutes and those employed through escort agencies. Both freelancers and agencies may advertise under the term "bodywork" in the back of alternative newspapers, although some of these bodywork professionals are straightforward massage professionals.

Typically, an agency will charge its escorts either a flat fee for each client connection or a percentage of the prearranged rate. In San Francisco, it is usual for typical heterosexual-market agencies to negotiate for as little as $100 up to a full 50% of a woman's reported earnings (not counting any gratuity received). Most transactions occur in cash, and optional tipping of escorts by clients in most major U.S. cities is customary but not compulsory. Credit card processing offered by larger scale agencies is often available for a service charge.^[46]

Escorts and escort agencies have historically advertised through classified ads, yellow pages advertising, or word-of-mouth, but in more recent years, much of the advertising and soliciting of indoor prostitution has shifted to internet sites. Sites may represent individual escorts, agencies, or may run ads for many escorts. There are also a number of sites in which customers can discuss and post reviews of the sexual services offered by prostitutes and other sex workers. Many sites allow potential buyers to search for sex workers by physical characteristics and types of services offered.

Internet advertising of sexual services is offered not only by specialty sites, but in many cases by more mainstream advertising sites. Craigslist for many years featured an "adult services" section of this kind. After several years of pressure from law enforcement and anti-prostitution groups, Craigslist closed this section in 2010, first for its U.S. pages, then some months later internationally. In March 2018 the personals section of Craigslist was closed down. In 2017, the "Adult" section of Backpage was closed down.^[47] Currently, internet advertising is the most important resource for anyone interested in prostitution. There are websites catering to different clientele, from upscale escorts to budget low end.

With the exception of some rural counties of Nevada, brothels are illegal in the United States.^[48] Along with these legal brothels in Nevada, commercial sex also occurs. Due to the topic regarding legal prostitution, the rights of these establishments are neglected. Both participants in establishments such as brothels, are subjected to background checks, cleanliness checks, and working licenses at the government's request.^[49] Aside from this, many massage parlors, saunas, spas, and similar otherwise-legal establishments serve as fronts for prostitution, especially in larger cities. They tend to be located in cities or along major highways.^[50]

Nevada is the only U.S. jurisdiction to allow some legal prostitution. Currently six of Nevada's seventeen counties have active brothels (all being rural counties); as of February 2018, there are 21 brothels in Nevada.^[51] Prostitution outside the licensed brothels is illegal throughout Nevada. Prostitution is illegal in the major metropolitan areas of Las Vegas, Reno, and Carson City, where most of the population lives; more than 90% of Nevada citizens live in a county where prostitution is illegal.

In addition, it is decriminalized to sell sex, but illegal to buy sex in Maine.

Prostitution in Rhode Island was outlawed in 2009. On November 3, governor Donald Carcieri signed into law a bill which makes the buying and selling of sexual services a crime.^[27] Prostitution was legal in Rhode Island between 1980 and 2009 because there was no specific statute to define the act and outlaw it, although associated activities such as street solicitation, running a brothel and pimping were illegal.

Louisiana is the only state where convicted prostitutes are required to register as sex offenders. The State's crime against nature by solicitation law is used when a person is accused of engaging in oral or anal sex in exchange for money. Only prostitutes prosecuted under this law are required to be registered. This has led to a lawsuit filed by the Center for Constitutional Rights.^[52]

The federal government also prosecutes some prostitution offenses. One man who forced women to be prostitutes received a 40-year sentence in federal court.^[53] Another was prosecuted for income tax evasion.^[54] Another man pleaded guilty to federal charges of harboring a 15-year-old girl and having her work as a prostitute.^[55] Another federal defendant got life imprisonment for sex trafficking of a child by force.^[56]

The ban on prostitution in the US has been criticized from a variety of viewpoints.^[57]

In 2020, some elected officials introduced bills to legalize prostitution in the state, but those have not received widespread support.^[58] The State did however repeal an anti-loitering law that critics argued discouraged street prostitution and targeted transgender people.^[59][60]

Local district attorneys have significant discretion over how to enforce existing prostitutions offenses. In New York City, District Attorneys often dismiss cases after community service is complete.^[61] In January 2021, the Brooklyn DA office stated that it will dismiss over a 1,000 warrants based of prostitution in the past 50 years, and erase prostitution in the crime history of over 25,000 people who were convicted of prostitution.^[62] Despite this, the issue often comes up in District Attorney elections, such as most recently in Manhattan, where prominent attorneys for the city, notably P. A. Potter the assistant DA for the borough, included an amnesty for sex workers as part of his successful campaign.^[63] Some New York District Attorneys have stated their support for the Nordic Model, however this came with backlash from sex worker advocates who oppose the prosecution of buyers.^[64]

One 1990 study estimated the annual prevalence of full-time equivalent prostitutes in the United States to be 23 per 100,000 population based on a capture–recapture study of prostitutes found in Colorado Springs, CO, police and sexually transmitted diseases clinic records between 1970 and 1988.^[65]

A continuation of the Colorado Springs study^[66] found a death rate among active prostitutes of 459 per 100,000 person-years, which is 5.9 times that for the (age and race adjusted) general population. Many people view prostitution as a victimless crime, as usually both sides are in agreement. However, many statistics show that it is very physically dangerous. The death rate per 100,000 of prostitutes in the U.S. is nearly double that of Alaskan fishermen.^[67]

Among voluntary substance abuse program participants, 41.4% of women and 11.2% of men reported selling prostitution services during the last year (March 2008).^[68] In Newark, New Jersey, one report claims 57 percent of prostitutes are reportedly HIV-positive, and in Atlanta, 12 percent of prostitutes are possibly HIV-positive.^[69]

A 2004 TNS poll reported 15 percent of all men have paid for sex and 30 percent of single men over age 30 have paid for sex.^[70] Over 200 men answered ads placed in Chicago area sex service classifieds for in depth interviews. Of these self-admitted "johns", 83% view buying sex as a form of addiction, 57% suspect that the women they paid were abused as children, and 40% said they are usually intoxicated when they purchase sex.^[71]

The prostitution trade in the United States is estimated to generate $14 billion a year.^[72] A 2012 report by Fondation Scelles indicated that there were an estimated 1 million prostitutes in the U.S.^[73]

John schools are programs whose mission is the rehabilitation of purchasers of prostitution.^[74] A mandated program that is used as treatment for men who have been detained for soliciting sex from prostitutes. This program consists of several therapy sessions and informational meeting regarding legal actions, the dangers, and lasting outcomes that may take place as a result of soliciting sex from a prostitute.^[74] In the first 12 years of the ongoing program, now denominated the "First Offender Prostitution Program", the recidivism rate of offenders was reduced from 8% to less than 5%. Since 1995, similar programs have been implemented in more than 40 communities in the US, including Washington, D.C.; West Palm Beach, Florida; Buffalo and Brooklyn, New York; and Los Angeles, California. An audit in 2009 of the first john school in San Francisco, California by the budget analysts of the City faulted the program with poorly defined objectives and absence of a method to determine its efficacy. Despite being touted as a national model for which taxpayers pay nothing, the audit stated that the program did not fully cover its expenses in each of the preceding 5 years, which resulted in a deficit of $270,000.^[75]

Sex trafficking includes the transportation of persons by means of coercion, deception and/or force into exploitative and slavery-like conditions,^[76] and is commonly associated with organized crime.^[77][78]

It has been estimated that two-thirds of trafficking victims in the United States are US citizens. Most victims who are foreign-born come into the US legally, on various visas.^[79] State Department estimated that between 15,000 and 50,000 women and girls are trafficked each year into the United States.

The measures against trafficking of women focus on harsher criminal legislation and punishments, and improving international police cooperation. There are vast media campaigns which are designed to be informative to the public, as well as policy makers and potential victims.^[77][80][81]
