The growth and proliferation of sociological immigration research has garnered sufficient attention to warrant a review and evaluation of the development of the field. This study took the first step by collecting detailed information about work published in the area of immigration research from major journals between 1990 and 2004. We explored three major areas: research topics addressed, theoretical frameworks employed, and population groups studied in the published literature. We compared the development of the field in the United States and Canada. The studies reveal several important patterns in the sociological publications of the United States and Canada. First, the topics studied and population groups included in the sociological publications on immigration are closely associated with the demographic and immigrant integration context of the country. Second, the publications as a whole show that in the development of immigration literature, researchers in the field are engaging in the general sociological theoretical discussion.
