Make note of bias, but remember that finding bias does not necessarily mean that the source cannot be used — it is, however, something to be aware of. If you use a source that you find to have questionable reliability make sure to make the reader aware in your source criticism.
For facts like statistics you should try to find information that is a first hand source and if this is not possible, a source as close to the information as possible.
