Yes, now that I think of it, you are correct; that would be including all of the city/county of Denver (such as Denver Tech Center). Nevertheless, the point remains every bit as valid. This building boom seems to be "sustainable" and "diverse." The investments in 16th Street mall, downtown sports venues (Coors Field, Pepsi Center and Invesco Field @ Mile High), the rebuilt and expanded Convention Center, Performing Arts center, and mass-transit; all have seem to stimulated an urban population boom into LoDo and the Central Platte Valley, which in turn is pumping more business investment (office, hotel and residential) into all of downtown.
The July 1, 2007 Census estimates are out and the City of Denver gained over 12,000 people between July 1, 2006 and July 1, 2007. Denver now has 588,349 people as of July 1, 2007 (last year). That means Denver could very well be sitting right at 600,000 people, as we speak. This is quite a steppingstone for a small, landlocked city center of a vast metro area.
