Immigration patterns in the United States have changed over time according to economic needs. Recent immigrants have clustered on the East and West Coasts as well as border states, often settling in ethnic communities located in poor, urban areas. While many immigrants initially take low-paying jobs, their incomes, education levels, and home ownership rates tend to increase the longer they live in the U.S. Immigration is a politically divisive issue, with Democrats generally supporting fewer restrictions and Republicans traditionally calling for more controls.
