City limits are not the metro area.

These figures describe the Census legal-place boundary for Las Vegas. They do not measure the continuously developed urban area or the larger metropolitan statistical area, which can include nearby cities, suburbs, and counties. Use the same geography when comparing places: city-to-city for these figures, or metro-to-metro in the metro population explorer.

How the figures are calculated.
