AVELLA ALAMINOS, Isabel. Las fuentes estadísticas para el estudio del comercio exterior mexicano entre 1920 Y 1947. Am. Lat. Hist. Econ [online]. 2011, n.35, pp.117-146. ISSN 2007-3496.

In this article the author identifies, examines and compares the main statistical data which is available to study the value of Mexico's foreign trade between 1920 and 1947, a period when the country entered the import substitution era. Based on this analysis, the author establishes the origin of the differences between the series, and also points out its limitations, so that the researchers interested in the topic are aware of the nature of the data they must deal with.
