Improvement of the data and documentation depends, in part, on feedback from users who share with us their complaints, suggestions, and observations about errors, inconsistencies, gaps, and lack of clarity in the data and documentation. We ask users of this preliminary version of the data to notify the IPUMS-International staff about any errors or problems they encounter and to participate, if asked, in an electronic survey about their use of the data and how the materials could be improved.

Please send your comments and suggestions to ipumsi@pop.umn.edu .
