A site search is a powerful tool for smart web searching and finding statistics. Put simply, this is a Google search that limits results to certain types of websites. In Google (or any other search engine), you type your search term, the search function "site:", and the domain of the website that you want to limit your results to (like .gov or .org)
This site search limits results to websites within the .gov domain
This site search limits results to websites within the UN.org domain
Go to the source - ask yourself "who cares?" Who cares about this topic enough to collect data?
Follow the breadcrumbs - lots of stats can be found in the secondary literature. Look for citations to data/stats in articles, reports, and even news
Use Library resources- the library spends a lot of money on subscription resources. Many of these are strictly for data/stats! Check out our offerings in A to Z Databases Statistics
