Datasets

This guide provides an introduction to data sets and offers resources for locating and using data sets for secondary analysis.
Accessing US Government Data

Internet Archive

For PAU researchers who are no longer able to access federal data being used in current research projects, the Internet Archive's Wayback Machine is available for searching past iterations of webpages where data used to be posted. Restoration instructions and a video are available from Choice, a publishing unit for the Association of College and Research Libraries, a division of the American Library Association.

The Internet Archive also hosts a page of archived datasets uploaded from the Centers for Disease Control and Prevention (CDC) website prior to January 28, 2025.

ICPSR

The PAU Library provides subscription access to the Inter-university Consortium for Political and Social Research (ICPSR), which is actively partnering with data archivists nationwide to manage existing and new government data for continuous access.

DataLumos

DataLumos is a repository of US government and social science data that archives resources for public access through community crowd-sourcing and in association with ICPSR. DataLumos datasets can be searched and downloaded at no cost. Datasets can also be uploaded to make them freely available to other researchers.

Data Rescue Project

The Data Rescue Project identifies current collaborative data rescue efforts, tracks the status and availability of resources, provides a means of contributing data and engaging in other volunteer activities, and offers downloads of rescued data.
