Step-by-step explanation:
The influx of immigrants in the late 1880s had a significant impact on the industrial workforce. As industrialization and urbanization increased, newly arrived immigrants sought employment in urban factories. The number of industrial workers in the nation quadrupled from 2.5 million to over 10 million between 1880 and 1920, largely due to the influx of immigrants.
