The issue of immigration, legal and illegal, has political and economic ramifications. An important component of the issue is how well immigrants integrate into the American economy. A University of Florida study attempted to answer this question. Researchers randomly surveyed U.S.- born Americans, immigrants who arrived in the United States before 1980, and immigrants who arrived after 1980 in Miami-Dade County, the state of Florida, and the United States. Each respondent was employed full-time and was asked to report his or her annual earnings. Conduct tests to determine whether differences exist between the three groups in each of the three geographic regions.
