Las Vegas Strip in the context of "Welcome to Fabulous Las Vegas"

Las Vegas, colloquially referred to as Vegas, is the most populous city in the U.S. state of Nevada and the seat of Clark County. It is the 24th-most populous city in the United States, with 641,903 residents at the 2020 census. The Las Vegas metropolitan area has an estimated 2.4 million residents and is the 29th-largest metropolitan area in the country. Las Vegas is an internationally renowned major resort city, known primarily for its gambling, shopping, fine dining, entertainment, and nightlife. Most of these venues are located in downtown Las Vegas or on the Las Vegas Strip, which is outside city limits in the unincorporated towns of Paradise and Winchester. The Las Vegas Valley serves as the leading financial, commercial, and cultural center in Nevada.

Las Vegas was settled in 1905 and officially incorporated in 1911. At the close of the 20th century, it was the most populated North American city founded within that century. Population growth has accelerated since the 1960s and into the 21st century, and between 1990 and 2000 the population increased by 85.2%.

Signage is the design or use of signs and symbols to communicate a message. Signage also means signs collectively or being considered as a group. The term signage is documented to have been popularized in 1975 to 1980.

Signs are any kind of visual graphics created to display information to a particular audience. This is typically manifested in the form of wayfinding information in places such as streets or on the inside and outside buildings. Signs vary in form and size based on location and intent, from more expansive banners, billboards, and murals, to smaller street signs, street name signs, sandwich boards and lawn signs. Newer signs may also use digital or electronic displays.

Clark County is the southernmost and most populous county in the U.S. state of Nevada, with 2,265,461 residents as of the 2020 census. The county is the location of the state's three largest cities, Las Vegas (the county seat), Henderson, and North Las Vegas, as well as the Las Vegas Strip, Nellis Air Force Base, and Hoover Dam. Clark County has 8,061 square miles (20,880 km) of land area, roughly the size of New Jersey.

Although the county has 70% of Nevada's population making it the 11th-most populous county in the United States, Clark County covers only 7% of Nevada's land mass. Despite having the name Las Vegas as part of their address, over 1 million residents live in unincorporated Clark County, with municipal services provided by the county. The county plays a role much larger than is typical in the US as it has direct jurisdiction over the Las Vegas Strip and such a large population.

The Las Vegas Valley is a major metropolitan area in the southern part of the U.S. state of Nevada, and the second largest in the Southwestern United States. The state's largest urban agglomeration, the Las Vegas Metropolitan Statistical Area is coextensive since 2003 with Clark County, Nevada. The Valley is largely defined by the Las Vegas Valley land formation, a 600 sq mi (1,600 km) basin area surrounded by mountains to the north, south, east and west of the metropolitan area. The Valley is home to the three largest incorporated cities in Nevada: Las Vegas, Henderson and North Las Vegas. Eleven unincorporated towns governed by the Clark County government are part of the Las Vegas Township and constitute the largest community in the state of Nevada.

The names Las Vegas and Vegas are interchangeably used to indicate the Valley, the Strip, and the city, and as a brand by the Las Vegas Convention and Visitors Authority to denominate the region. The Valley is affectionately known as the Ninth Island by Hawaii natives and Las Vegans alike, in part due to the large number of people originally from Hawaii who live in and regularly travel to Las Vegas.

A call for service (CFS, also known as a job, hitch, incident, callout, call-out, or simply a call) is an incident that emergency services or public safety organizations (such as police, fire departments, and emergency medical services) are assigned to resolve, handle, or assist with. Operationally, a call for service is any incident where emergency services are a third-party intervener, regardless of whether their presence was requested or they came across it in the course of their duties.

The term "call" originates from the telephone calls made by the public to emergency telephone numbers to report the incident to dispatchers and request an emergency service response. There are two types of calls for service: dispatched calls, which are made by members of the public through emergency number calls; and self-initiated, self-generated, or directed calls, which are made by emergency services personnel.

A casino is a facility for gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shopping, cruise ships, and other tourist attractions. Some casinos are also known for hosting live entertainment, such as stand-up comedy, concerts, and sporting events. The term casino is of Italian origin, from the root word casa meaning "house." Originally, the term referred to a small country villa, summerhouse, or social club. During the 19th century, casino came to encompass other public buildings where pleasurable activities took place.

The precise origin of gambling is unknown, but it is believed to have existed in nearly every society in history. The first known European gambling house, the Ridotto, was established in Venice, Italy, in 1638 to provide controlled gambling during the carnival season. In the United States, early gambling establishments were known as saloons. In the early 20th century, gambling was outlawed in the US by state legislation. However, in 1931, gambling was legalized in Nevada, leading to the rise of Las Vegas as a major gambling center. In 1976, New Jersey allowed gambling in Atlantic City, which is now the second-largest gambling city in the US.

Downtown Las Vegas (commonly abbreviated as DTLV) is the central business district and historic center of Las Vegas, Nevada, United States. It is the original townsite, and the Downtown Gaming Area was the primary gambling district of Las Vegas prior to the Strip. As the urban core of the Las Vegas Valley, it features a variety of hotel and business highrises, cultural centers, historical buildings and government institutions, as well as residential and retail developments. Downtown is located in the center of the Las Vegas Valley and just north of the Las Vegas Strip, centered on Fremont Street, the Fremont Street Experience and Fremont East. The city defines the area as bounded by I-15 on the west, Washington Avenue on the north, Maryland Parkway on the east and Sahara Avenue on the south.

Paradise is an unincorporated town and census-designated place (CDP) in Clark County, Nevada, United States, adjacent to the city of Las Vegas. It was formed on December 8, 1950. Its population was 191,238 at the 2020 census, making it the fifth-most-populous CDP in the United States; if it were an incorporated city, it would be the fifth-largest in Nevada. As an unincorporated town, it is governed by the Clark County Commission with input from the Paradise Town Advisory Board.

Paradise contains Harry Reid International Airport; the University of Nevada, Las Vegas (UNLV); the majority of the Las Vegas Strip; and most of the tourist attractions in the Las Vegas area (excluding downtown). However, all Paradise addresses, as well as other unincorporated areas in the Las Vegas Valley, have "Las Vegas" addresses.
