Official Measurement

The GDP Deflator is reported by the Bureau of Economic Analysis (BEA), using 2005 as the base year — meaning, the deflator for 2005 is set to 100 with other years reported relative to the 2005 dollar.

Examples

The GDP Deflator for 2010 was 110.99. On average the 2005 dollar could buy (10.99/100) 10.99% more than the 2009 dollar.

The GDP Deflator for 1950 was 14.65. On average the 1950 dollar could buy (100/14.65) 6.82 times as many goods as the 2005 dollar.
