The following datasets come from studies undertaken by the Center for Migration and Development or its members during the last ten years; or by its director, Alejandro Portes, in prior years.

When possible, the information available for each survey includes a codebook, an ascii data file and Stata and SPSS system files. Most of the codebooks are in Princeton's Office of Population Research's own cdx format and present values, value labels, and frequencies.   

The Comparative Immigrant Organization Project (CIOP)

This survey of 89 Colombian, Dominican, and Mexican organization leaders and additional interviews with community activists and government officials is part of a larger study of the organizations constructed by Latin American immigrants in the United States and their impact on the political incorporation of these immigrants to American society. This specific dataset was designed to give us greater understanding of the forces creating and sustaining these organizations and to test several preliminary hypotheses about the effects of contexts of exit and modes of incorporation in receiving countries on the character of immigrant transnationalism. Accordingly, there are detailed measures of the extent of economic, political, and socio-cultural transnationalism and characteristics of both the organizations and their members. The published files include a codebook and STATA-formatted data file.

The Comparative Immigrant Entrepreneurship Project (CIEP)

The CIEP survey of over 1,200 Colombian, Dominican, and Salvadoran family heads is the first to explicitly measure the extent of economic, political, and socio-cultural transnationalism among immigrants and to develop predictive models of these activities.  The published files include an explanatory statement of the study, a codebook, and data files in both SPSS and STATA format readily available for analysis.  Results from CIEP have been published in major sociology journals and in specialized journals in the field of immigration.  However, there is a great deal of additional information in these files that remains unanalyzed and that will be of interest to researchers in this field.  For additional details, please view the description of the study.

The Children of Immigrants Longitudinal Study (CILS)

CILS is a longitudinal study designed to study the adaptation process of the immigrant second generation which is defined broadly as U.S.-born children with at least one foreign-born parent or children born abroad but brought at an early age to the United States.  For details, please read the description of the study and Notes for Specific Variables

Cuban and Mexican Immigrants in the U.S.

The aim of this longitudinal study, based on data on Cuban and Mexican immigrants to the USA collected in 1973-74, was to map the process of immigrant adaptation and incorporation into the labour market. For more details please consult the description of the study. The information available for the two samples of Cuban and Mexican immigrants includes a codebook, an ascii data file, and a Stata-6 system file. (These files were prepared at OPR from the original codebook and listing, and are much more compact. For example the raw data file was reduced from 2.3 MB to 357 KB.) We have available the spanish questionnaire in pdf format.

Caribbean Urbanization in the Years of the Crisis

This is a project undertaken in 1991-94 to examine theories of Third World urbanization in a Caribbean and Central American context. The project fielded surveys in Costa Rica, the Dominican Republic, Guatemala, Haiti and Jamaica.

To learn more about the project read a detailed description of the study. A copy of the spanish questionnaire is available in plain text format. We now have available the english questionnaire in pdf format. You can also read the guidelines for interviewers and the guidelines used in the construction of code books, in plain text format and in pdf format.

The Adaptation Process of Cuban and Haitian Refugees

This study focuses on two samples of refugees living in southern Florida: a group of 514 Cuban refugees who arrived as part of the Mariel boat lift of 1980, and a sample of 500 Haitian refugees who arrived between 1980 and 82. For more information please consult a detailed study description.

Mexican Migration Project (MMP)

The Mexican Migration Project (MMP) is a multidisciplinary research effort between investigators in Mexico and the United States.  It has offices in Mexico at the Departmento de Investigacion sobre Movimientos Sociales of the University of Guadalajara and in the United States at the Office of Population Research of Princeton University.  For more information, please visit the Mexican Migration Project.

The Latin American Migration Project (LAMP) is a collaborative research project based at Princeton University and the University of Guadalajara.  The LAMP was born as an extension of the Mexican Migration Project (MMP), which was created in 1982 by an interdisciplinary team of researchers to advance our understanding of the coplex processes of international migration and immigration to the United States.  Data gathered by the MMP have been the source of a sizable amount of research on international migration.  The purpose of the LAMP is to extend this research to migration flows originating in other Latin American countries.  Please visit the LAMP for more information.

 

New Immigrant Survey (NIS)

The New Immigrant Survey (NIS) is a nationally representative multi-cohort longitudinal study of new legal immigrants and their children to the United States based on nationally representative samples of the administrative records, compiled by the U.S. Immigration and Naturalization Service (INS), pertaining to immigrants newly admitted to permanent residence. Please visit NIS for more information.
