Real GDP in Chained (2005) Dollars
Currently, the U.S. Department of Commerce uses the more complicated chained-dollar method to remove the effects of inflation. This method is able to address anomalies that occur when new products are introduced, when product quality changes over time, and when prices fall because of improved production techniques. The personal computer is the textbook example of this kind of change - introduced in the mid-1980s, with quality increasing and production costs declining dramatically over the next three decades.
It doesn’t make sense on any level to account for the value of computers by pricing today’s computers at 1990 price levels.
Generally, “Real GDP” statistics are calculated by prices from 2005 and is labeled as “GDP in chained (2005) dollars.”
Every year, Bureau of Economic Analysis (BEA) releases four quarterly GDP statistics and annual GDP in both current dollars and chained (2005) dollars.
