Data Revisions

Which statement would be most accurate in a New York State study guide about Data Revisions?

• A seasonally adjusted annual rate expresses a quarter’s pace as if sustained for a year and should not be read as literal quarterly production.
• Current-dollar GDP measures production at prevailing prices and therefore combines quantity and price effects.
• BEA revisions are part of normal statistical production and make publication dates essential metadata for state-economy research.
• State GDP rankings require consistent metric definitions, periods, and releases because nominal, real, annual, and quarterly series answer different questions.
