If you can't find the data you need, try looking for statistics in journal, magazine, or newspaper articles.
This page illustrates some ways to find statistics within articles in a selection of databases: Ebscohost, and ProQuest. You can apply similar techniques in many other databases.
EBSCOhost's Academic Search Complete: When searching for statistics in an Ebscohost database try an advanced search. In the first box type in your search term (your keyword), in the next box type in the word statistics and change the drop down from Select a Field to SU Subject Terms.
In Ebscohost you can also enter a search term (your keyword) and then select graph or chart in Image Quick View Types. The results will include articles with graphs and charts that often contain statistical information.
