Data and statistics can be great supplements to books and journal articles.
We subscribe to a couple of statistical databases, which are good places to start.
Think about where you might find the type of information you are looking for, and what type of organization might be collecting and sharing that information.
Non-profit organizations, think tanks, and policy groups
Look for tabs or options on the website for "data," "statistics," "reports," or "publications."
To search for data and statistics in Google, try the following:
Type in your topic, add the word "data" or "statistics" and then add "site:.gov" or "site:.edu" to limit the results to ony those with a .gov or .edu domain name.
If you want to only recieve Excel files or PDFs, you can limit the Google search by add "filetype:.pdf" or "filetype:.xls"
