The Mexican Migration Project is pleased to make available to the public its new database: MMP134.

The MMP134 database has 134 communities in 22 states, which includes the original 128 communities plus 6 new additional communities: 2 from San Luis Potosi, 3 from Puebla, and 1 from Guanajuato state.

MMP134 database is available in: SAS, Stata, and SPSS format. Instead of offering datasets by state, now we are offering the syntaxis to cut the dataset into states.

To access the data please visit the OPR's archive webpage. Registration is required for access.

We have also updated our supplementary datasets until year 2010: COMMUN, NATLYEAR and NATLHIST. In addition, we have added montly rain data until 2010 to our ENVIRONS dataset.

There was one modification on the MIG and MIGOTHER file. Originally, the variables RELTRIP, PAISTRIP, FINHELP, and LODGING were aimed to measure characteristics on the last trip only. However, in 2000, they were modified to measure characteristics on the first trip. Now in 2011, you'll find two sets of variables: ones designed for first trip and the latter designed for last trip. To understand this change, please visit the Documentation - Questionnaire section and revise our various versions through time.

If you find any problems with the data, please report them to us by sending e-mail directly to mmp@opr.princeton.edu, this truly help us to keep data as accurate as possible.

This release supersedes all earlier releases of the data.
