Tucson grew 20 percent in population and 24 percent in area from 1990 to 2000.  Of the 273 U.S. cities with populations over 100,000, Tucson's growth was 71st greatest in percent change, and 23rd greatest in absolute change from 1990 to 2000. Only seven cities larger than Tucson grew at a more rapid rate from 2000 to 2008; five cities larger than Tucson lost population during the same time period.

The Tucson Metropolitan Area was 58th largest in 2000, and only 10 larger metro areas grew faster. Much of the growth over the next 20 years will be driven by working age people moving here for employment opportunities. In 2002, the Tucson urbanized area was 69th most dense of the 141 urban areas with populations over 250,000, in the United States and Canada.

The City of Tucson is nearly as large in population as the State of Wyoming and in area is more than three times the size of Washington, D.C. In 2010, Tucson was the nation’s 33rd largest city.
