Immigration Theory for a New Century: Some Problems and Opportunities

Portes, Alejandro·1997·International Migration Review

Abstract

This essay examines some of the pitfalls in contemporary immigration theory and reviews some of the most promising developments in research in this field. As a data-driven field or study, immigration has not had to contend with grand generalizations for highly abstract theorizing. On the contrary, the bias has run in the opposite direction, that is toward ground-level studies of particular migrant groups or analysis of official migration policies. As the distillate of past research in the field and a source of guidance for future work, theory represents one of the most valuable products of our collective intellectual endeavor. Ways to foster it and problems presented by certain common misunderstandings about the meaning and scope of scientific theorizing are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
