Instructions to Download the MMP Data Files

ACCESS

ALL files contained in the MMP website are available for public use. We have taken measures to ensure the confidentiality of our respondents. However, to further ensure the confidentiality of our data, we request that you fill out a registration form prior to downloading the files. By submiting the registration form you agree to:

  1. Use the data contained only for research or educational purposes
  2. Not try to identify any individual, household or migrant community
  3. Not give access to your copy of the MMP database to other users who do not agree to respect these confidentiality terms.

If you registered for the MMP71 at the University of Pennsylvania you DO NEED TO REGISTER AGAIN.

(Note: We suggest that you recommend for everyone who wants to use the MMP database to visit our website in order to download their own copy)

To download double click on the file of your choice. A pop-up window will allow you to save the file to a folder of your choice on your computer.  

OPEN FILE

To save space and reduce transfer time we have COMPRESSED all files, except NATLYEAR and NATLHIST. You will need to uncompress the files before you can work with them.

We have compressed the files using the "zip" program. A common unzip utility for Windows is WinZip which you can download from the web. Follow this link to install WinZip on your computer (make sure you don't already have WinZip installed):
