It grew rapidly in the mid-19th century; by 1860, Chicago was the youngest U.S. city to exceed a population of 100,000. The Great Chicago Fire in 1871 destroyed several square miles and left more than 100,000 homeless, but Chicago's population continued to grow to 503,000 by 1880 and then doubled to more than a million within the decade. The construction boom accelerated population growth throughout the following decades, and by 1900, less than 30 years after the fire, Chicago was the fifth-largest city in the world. Chicago made noted contributions to urban planning and zoning standards, including new construction styles (such as, Chicago School architecture, the development of the City Beautiful Movement, and the steel-framed skyscraper).
