Out of all the cities in Nevada, the one city with the greatest population is Las Vegas. In 2010, the city population was 583,756. Based on percentage, Las Vegas is one of fastest growing metropolitan areas and it is located in the Sun Belt.
The largest hotel and casino within the Las Vegas city is the Golden Nugget. The Strip is not within city limits, but the larger and more well known casinos are located in that area.
This hotel, The Mirage (housing one of the greatest Cirque Du Soleil shows, The Beatles LOVE, is a MUST WATCH!! It is amazing!) opened in 1989 and created a redevelopment to the Las Vegas Strip. With all the major high end resorts opening in an area outside of the downtown Las Vegas Strip that was not located within Las Vegas city limits, tourism in the downtown area suddenly declined. There have been many attempts to revive the "old feel Las Vegas" location, but it just cannot compete with the high rise, entertainment, restaurants, and clubs of the resorts on the Las Vegas Strip.
