Aurora, Colorado

Aurora is a home rule city in the U.S. state of Colorado that reaches across Arapahoe, Adams and Douglas counties on the eastern side of the Denver area. It recorded 386,261 residents at the 2020 census, which makes it the third largest city in Colorado, and it serves as a principal city of the Denver metropolitan area within the Front Range Urban Corridor. The community began in 1890 as the real estate venture of a Denver businessman and was first called Fletcher. A water debt left by its founder led voters to rename it Aurora in 1907, after one of the subdivisions that made up the town, and it was reincorporated as a city in 1928. The city grew quickly in the late twentieth century and now covers more land than neighboring Denver, with a semi-arid climate and a rise of about a thousand feet between its lowest and highest points.
