What is the difference between the Gilded Age and the Ashcan School?

The Ashcan School was an artistic movement in the United States that began in the early 1900s. The movement focused on New York City's daily life, specifically their poorer neighborhoods. The Ashcan School was largely a painting movement, and some of its popular figures included William Glackens, John Sloan and Robert Henri. 

The Gilded Age, on the other hand, is a time period that lasted from the 1870s to 1900. It is a term coined by Mark Twain, and it describes an era of severe social problems covered up by a golden lining. During this time period, the North and West of America experienced rapid economic growth. American wages were higher than European wages, but the social problems within the United States were severe.

The Gilded Age occurred before the Ashcan School came about, but the Ashcan School grew out of the artistic sensibilities that were established during The Gilded Age.
