40% of numerical facts, 50% lies in America? (6)

I believe the answer is:

states

'america?' is the definition.
(the United States)

I don't understand how the rest of the clue works.

(Other definitions for states that I've seen before include "Conditions or circumstances" , "Proclaims" , "They're united in America" , "Says; conditions" , "America; says" .)

I've seen this clue in The Guardian.
