Frequently asked questions
What link should be checked before matching results?
Keep producer, resource and series code; align population, unit and period.
What if sources appear to contradict each other?
For differing figures, check base, adjustment and revision before choosing a value.
Do the listed portals provide independent confirmation?
Not necessarily. Identify the producer and underlying document. Two interfaces distributing one item can check transcription but do not establish a fact independently twice.
