Statistical compendia such as  Nationmaster (free web)  are an excellent first place to look for statistics and sources of data when you don't know who might be interested in collecting the data you need.

Even if the compendium does not have the exact data you need, use it as a "guide to data sources" by studying the source notes.

The Data guide provides a list of compendia to help you start your search.
