During the gilded age the majority of immigrants to the United States moved to big cities where they generally lived in enclaves with other immigrants of the same ethnicity.
The Gilded Age in United States history refers to the late 19th century, from the 1870s to about 1900. The term for this period started to be used in the 1920s and 1930s and stemmed from writer Mark Twain's and Charles Dudley Warner's 1873 novel The Gilded Age: A Tale of Today, which describes an era of serious social problems.
