About the AIA Architecture Billings Index

The Architecture Billings Index is derived from a monthly “Work-on-the-Boards” survey and produced by the AIA Economics & Market Research Group. The findings amount to a leading economic indicator that provides an approximately six month glimpse into the future of nonresidential construction activity. The indexes contained in the full report are derived from a monthly survey sent to a panel of AIA member-owned firms. Participants are asked whether their billings increased, decreased, or stayed the same in the month that just ended. According to the proportion of respondents choosing each option, a score is generated, which represents an index value for each month.
