The Factbook dates from a time when this was the most convenient source of updated concise summaries of all countries. It didn’t necessarily go into great detail except for countries important to the US national interest. This has been eclipsed by Wikipedia, the information there is far more comprehensive and govt officials will go there to make updates and corrections.

That's one way of putting it.
The Factbook dates from a time when facts mattered
Can we please, please not outsource everything to Wikipedia? Many of the editors there are hardly impartial
Where do you think the information on Wikipedia comes from? Not that Wikipedia strongly relies on The World Factbook, but it can't exist without other secondary sources like these.
