Which is correct: "the below information" or "the information below"?

Solution 1:

As a preposition, "below" would be written after "information" as a stranded preposition. While typically prepositions would precede the noun, stranded prepositions can occur "in interrogative or relative clauses, where the interrogative or relative pronoun that is the preposition's complement is moved to the start".

We see such a stranded preposition in the case of "the information below," and therefore the preposition follows it. By contrast, in the case of "the following information", an adjective is used to describe the noun and therefore may precede it.

In short, "the below information" is not generally accepted to be correct, because "below" is not universally acknowledged as an adjective. Nevertheless, some dictionaries specifically list this as an exception.

Solution 3:

Merriam-Webster lists a relevant definition:

below (adjective): written or discussed lower on the same page or on a following page

Given this, there is nothing wrong with “the below information”.

Solution 4:

"He lives on the below floor" or "He lives on the floor below"? -- If not grammar, at least usage is against the first mentioned way of saying it.
