Industrialization led to the growth of cities and urbanization during the 1800s because of the constantly growing population. Immigrants, people living in rural areas, and africans from the south came to the city in order to seek new opportunities, to find a better job, and to make more money. Many German and Irish immigrants escaped starvation or poverty in their countries to come to the US. They often came from the east, and many came to urbanized cities. People who lived in rural areas also came to urbanized cities in order to get more money, as jobs were being scarce on their farms, and they were paid very poorly. Free African Americans were facing a lot of discrimination in the south, and often times, they wouldn't be able to find a job
