The US population grew during the Gilded Age mainly because of a sharp rise in immigration. This period, roughly from the 1870s to the early 1900s, saw millions of immigrants arriving in the United States, contributing significantly to the population increase. Many of these immigrants were seeking economic opportunities and better living conditions, which were abundant in the rapidly industrializing economy of the time.
