Las Vegas is the most populous and most densely populated city in the state of Nevada. It is located in the south of the state, in Clark County.
According to the 2010 national census, the city itself has 583,756 inhabitants, and its metropolitan region has about 1.9 million inhabitants. It is the 30th most populous city in the United States and is considered to be the fastest growing city in all of North America.
Population growth was especially marked in the 1990s, when the population went from a little over 200,000 people to more than 500,000. This brought a consequent lack of resources due to the desert location of the city, which was solved only with investment in infrastructure by the state government.
