Finding Data & Statistics

A guide to finding statistical information and downloadable datasets

About Data Sets

The links on this page are to sites that contain downloadable data sets in formats that can be manipulated and reused. Many data sets will require statistical software packages, e.g. SPSS, Stata, R, etc.

► Many of these sources are intended for the more advanced data user.

These data sets are available in a variety of formats: csv, Excel, SAS, SPSS, Stata, etc.  Some may be available in multiple formats, some in only one .

Some are available only as Zip (compressed) files and you will need an application for "unzipping" or decompressing them.
