How are immigration industrialization urbanization connected

Industrialization created well-paid jobs in cities wich attracted a lot of people that were looking for a better life to an urban center. In some situations, even immigrants would come from other countries to work in factories. Therefore, the factories attract people to cities from the rural areas and from outside the country. 

Definitely the second and the last one from common sense. I also want to sort of say the first one as well, because communities did trade/sell slaves to Americans for necessities.
