Immigration impacted the social development of the United States. When immigrants came to this country, many settled in ethnic neighborhoods in large cities. In these neighborhoods, they could speak their own language and practice their own customs. By settling in neighborhoods such Little Italy and Chinatown, immigrants could learn about American ways of living from people of their own background, allowing these immigrants to get a foothold in the country while still maintaining some aspects of the culture and tradition from their homeland. Additionally, immigration contributed to the development of the diversity of the country, as people from all parts of the world settled in the United States, bringing with them their unique cultural characteristics.
Immigrants impacted the country economically because many of these immigrants provided a large supply of workers who could work in various jobs. Many immigrants did unskilled or physical labor such as running machines, working in mines, or building railroads. These immigrants added to the supply of available workers, which helped to keep wages lower and enabled these companies to increase their profit levels. Immigrants also helped to increase the demand for products and services, which benefitted American companies as well as the economy.
