Finding Data for Research

Looking for data for a research project? There is so much data to choose from that it can be overwhelming. To help students get started, we’ve created a list of commonly-used datasets that are accessible to most students, organized by the unit of analysis. If this list does not have what you’re looking for, scroll down for links to searchable websites.
