The Mexican Migration Project's (MMP) interdisciplinary team of researchers collects and analyzes social and economic information on "the complex process of Mexican migration to the United States." This bilingual Website makes the project's work publicly available for research and education. Included are background information about the MMP, Facts & Figures on migration, and a section entitled Expressions, which provides oral histories and online artistic exhibits to promote an "understand[ing of] the emotional reality of migration." However, the core of the site is the extensive MMP Database, which contains general demographic and migratory data on over 7,000 households surveyed in 52 Mexican communities and data on more than 500 households surveyed in the US. Unix and PC Users may download the compressed (.zip) MMP data files in either ASCII (.dat) or SPSS portable (.exp) formats. Corresponding technical documentation is also available in .pdf format. The MMP is a binational research initiative co-directed by Jorge Durand, Professor of Social Anthropology at the University of Guadalajara, and Douglas S. Massey, Professor of Demography and Sociology at the University of Pennsylvania.
