Are historical and forecast revenue adjusted for inflation? Are the figures real or nominal?

Are historical and forecast revenue adjusted for inflation? Are the figures real or nominal?

All historical and forecast dollar figures in the Performance and Key Statistics chapters of Industry Reports are real values adjusted for inflation using the current year (i.e., year published) as the base year. Adjusting values for inflation removes the impact of changes in the purchasing power of the dollar, leaving only the "real" growth or decline in industry metrics.
