Henderson is a city in Clark County, Nevada. The city is part of the Las Vegas metropolitan area, which spans the entire Las Vegas Valley. It is the second largest city in Nevada, after Las Vegas, with an estimated population of 257,729 in the 2010 census. It occupies the southeast end of the valley, at an elevation of approximately 1,330 feet . In 2011, Forbes magazine ranked Henderson as America's second safest city. Analysts attribute this to Henderson being a relatively affluent city, with a higher median income and amenities catering to local residents. This limits movement throughout the area and to nearby Las Vegas, which was subsequently ranked as the nation's ninth most dangerous city.
